Taxon Rosa canina subsp. inodora, commonly known as the Eglantine or Sweetbriar rose, typically has straight to slightly curved thorns that are not as strongly hooked or claw - like as those found on some other rose species (such as Rosa rubiginosa).
In contrast:
- Strongly curved, claw - like thorns: These are characteristic of species such as Rosa rubiginosa.
- Straighter thorns: This is typical for Rosa canina subsp. inodora.
This distinction helps differentiate it from similar - looking species within the genus Rosa.

Taxon Rosa canina subsp. inodora, commonly known as dog rose or sweetbriar, can still be reliably identified even after autumn frosts have caused its leaves and sepals to fall off. Here are key identification features for this species during winter months or after leaf drop:

1. Thorns

- The stems of Rosa canina subsp. inodora typically bear strong, straight thorns that are evenly distributed along the stem length. These thorns are a prominent feature and help distinguish it from other deciduous roses.

2. Buds and Flowers (Remains)

- Even though flowers and sepals may have withered away, dried - up flower stalks and remnants of hip pedicels often remain attached to the plant. These structures can provide clues about the previous blooms' characteristics.

3. Hips

- One of the most distinctive features is the presence of persistent hips (fruit), which are usually bright red or orange - red in color. They tend to persist well into winter and are an excellent diagnostic trait.

4. Stem Characteristics

- The stems are generally stout, erect, and arching. They exhibit smooth bark on younger parts but become rougher and more furrowed with age. The overall shape and texture of the branches contribute significantly to distinguishing between different rose species.

5. Prickles vs. Thorns

- While many rose species have prickles (short, weak projections), Rosa canina subsp. inodora has true thorns - hardened, sharp outgrowths from the wood itself. This distinction is crucial for proper identification.

6. Branch Structure

- Look at how the branches grow. Rosa canina subsp. inodora tends to form dense, arching shrubs with multiple stems arising from the base. Its growth habit can differ slightly depending on habitat conditions but remains characteristic.
By focusing on these traits - thorns, buds/hips, stem structure, and branch habit - it should be possible to identify Rosa canina subsp. inodora even without leaves or sepals present.

To properly assess and confirm the diagnostic "inodora" (odorless) characteristic of Rosa canina subsp. inodora, follow these steps:
1. Select Fresh Plant Material:
Collect a few freshly picked sepals directly from the flower buds or flowers of the plant you are examining. Seeds, hips (fruits), or dried parts should be avoided as they may not accurately reflect the odorless trait.
2. Crush the Sepals:
Carefully crush or rub the fresh sepals between your fingers. This action releases volatile compounds that will allow you to detect any scent.
3. Assess for Odor:
Immediately after crushing, bring the crushed sepal material close to your nose and inhale deeply. Note whether there is any noticeable fragrance or aroma.
4. Compare with Known Specimens:
If possible, compare this result with known specimens of other rose species or subspecies where odors might differ. This step helps confirm the absence of scent specific to inodora.
Conclusion:
If no distinct scent is detected upon crushing the fresh sepals, it supports the identification of the taxon as Rosa canina subsp. inodora.

Shape of Hypanthium (Fruit):
- Rosa canina subsp. inodora: The hypanthium is typically oval to oblong, often slightly flattened at the base, with a rounded apex. It has a distinctly smooth surface and a slight bloom that gives it a bluish cast when ripe.

Comparison with Related Species:

1. Rosa majalis:
- Hypanthium shape: Oval to nearly round. With this species, fruits are generally smaller compared to Rosa canina subspecies but still exhibit an overall rounded appearance.
2. Rosa rugosa:
- Hypanthium shape: Spherical to globose, usually larger than those of Rosa canina. subsp. inodora, with prominent sepals persisting on top of the fruit.
In summary, while all three species have some degree of ovate or rounded hypanthia, Rosa canina subsp. inodora tends toward more elongated forms compared to the more globular shapes seen in Rosa majalis and especially Rosa rugosa.

In Taxon Rosa canina subsp. inodora, the sepals typically remain erect.
This characteristic - sepals that stay upright - is an important feature for distinguishing this subspecies from other rose species where sepals may fall off early.

The main signs that indicate overripeness and the beginning of fermentation for Rosa canina subsp. inodora are indeed:
- Softening: The fruit becomes softer to touch, losing its firmness and texture.
- Dark Spots: Appearance of brown or black spots on the surface of the hips (fruits).
These changes signal that the fruit is past its prime ripeness stage and may start developing off - flavors due to degradation processes.

Collecting fruits of Rosa canina subsp. inodora that still have their sepals attached is generally not recommended for several reasons related to both quality and practicality:
1. Quality Concerns: Sepals may harbor microorganisms or pests, which could potentially contaminate the fruit during storage or processing. Additionally, sepals might contribute to a higher moisture content, increasing the risk of mold growth.
2. Processing Efficiency: Fruits with intact sepals require additional steps (such as manual removal) before they can be used effectively. This adds time and labor costs to the process.
3. Aesthetic Appeal: Removing sepals improves the appearance of the harvested product, making it more appealing for commercial use or consumption.
4. Nutritional Value: While the presence of sepals does not significantly alter the nutritional value of the hips themselves, removing them ensures cleaner and safer handling practices.
In conclusion, while it is technically possible to collect fruits with remaining sepals, doing so typically compromises the overall quality and efficiency of the harvest. It is advisable to wait until the sepals naturally fall off or remove them manually prior to collection for optimal results.

Determining the Best Harvest Time for Rosa canina subsp. inodora
The optimal harvest time for Rosa canina subsp. inodora, commonly known as dog rose hips, depends on your intended use and desired characteristics of the fruit.

Arguments for Harvest Before Frost

1. Higher Vitamin Content: Rose hips harvested before the first frost tend to have higher levels of vitamin C and other antioxidants. This makes them ideal for medicinal preparations such as teas, syrups, and supplements aimed at boosting immunity.
2. Preservation of Active Compounds: Early harvest helps preserve bioactive compounds that may degrade with exposure to freezing temperatures.
3. Prevention of Mold Growth: Harvesting earlier reduces the risk of mold development during storage.

Arguments for Harvest After Frost

1. Sweetness and Flavor Development: Freezing temperatures break down cell walls within the fruit, making it softer and sweeter. This enhances their palatability when used in culinary applications like jams, jellies, and desserts.
2. Enhanced Color and Aroma: Frosts often intensify the color and aroma of rose hips, which can be beneficial for aesthetic purposes in food presentation.
3. Natural Fermentation Process: Some traditional recipes rely on natural fermentation processes triggered by frost, enhancing flavor complexity.

Final Answer

- If you prioritize high nutritional value and plan to use the hips primarily for health benefits (tea, capsules), it's better to harvest before the first frost.
- For culinary uses where sweetness and enhanced flavors are crucial (jams, preserves), wait until after a light frost.
Both approaches have their merits depending on how you'll utilize the rose hips.

To determine the optimal ripeness of Rosa canina subsp. inodora (Dog Rose) fruits based on their color and firmness, follow these guidelines:

Color Indicators:

- Initial Stage: Fruits start greenish - yellow or light pink.
- Intermediate Stage: Gradually transition through shades of orange - red.
- Optimal Ripeness: Deep, dark red with a uniform color across the entire surface. Avoid fruits that are partially green or yellowish as they may not yet be fully ripe.

Firmness Indicators:

- Underripe: Fruits feel hard and somewhat brittle when pressed gently.
- Overripe: Become softer, almost mushy, and may show signs of wrinkling or shriveling.
- Perfectly Ripe: Should have a slight give when lightly squeezed but remain firm overall. They should not feel overly soft or squishy.

Additional Tips for Harvesting:

1. Observe Overall Plant Health: Healthy plants generally produce better - quality fruits. Look for vibrant foliage and no signs of disease or pests.
2. Harvest at Peak Sunlight Hours: For best results, harvest during mid - morning after dew has evaporated but before peak afternoon heat sets in.
3. Avoid Overharvesting: Ensure you leave some fruits on the plant to support future growth and seed dispersal.
4. Post - Harvest Storage: Store harvested hips in a cool, dry place away from direct sunlight to maintain freshness until processing.
By combining visual cues (deep red coloration) with tactile assessment (firm texture), you'll be able to identify perfectly ripe Rosa canina subsp. inodora fruits.

For Taxon Rosa canina subsp. inodora (Dog Rose), the time of day when collecting fruits (hips) can indeed affect their vitamin C content and overall quality.

Factors to Consider

1. Diurnal Variation:
Vitamin C levels fluctuate throughout the day due to photosynthesis and plant metabolism. Higher concentrations are typically observed during midday when sunlight is most intense, as this stimulates the production of antioxidants like vitamin C.
2. Environmental Conditions:
Collection should ideally occur on a dry, sunny day after morning dew has evaporated. This helps prevent mold growth and ensures that the hips are not waterlogged, which could dilute nutrient concentration.
3. Plant Stress:
Collecting hips too early or late in the day might result in lower yields or stressed plants. If collected under extreme heat or cold conditions, the fruit may have reduced nutritional value.
4. Practicality:
From a practical standpoint, mid - morning to early afternoon (around 9 AM to 3 PM) is often recommended. This period balances optimal light exposure with manageable temperatures, ensuring both high vitamin C content and ease of harvesting.

Conclusion

To maximize vitamin C content in Rosa canina subsp. inodora hips, it's best to collect them between mid - morning and early afternoon, particularly on clear days with moderate temperatures.

For Taxon Rosa canina subsp. inodora, which is commonly known as the odorless dog rose, the specific processing steps for drying its fruits (hips) may vary depending on your intended use and desired outcomes.

Considerations for Cutting or Crushing:

1. Speeding Up Drying Time
Cutting or crushing the hips into smaller pieces will significantly reduce their thickness, thus allowing moisture to evaporate more quickly from a larger surface area. This method accelerates the overall drying time.
2. Retention of Active Compounds
While cutting or crushing speeds up drying, it also exposes more surface area to potential degradation by light and air exposure. This could lead to some loss of volatile compounds and nutrients like vitamin C.
3. Ease of Storage and Use
Crushed or powdered dried hips are easier to store compactly and often used directly in teas, capsules, or extracts without further preparation. However, whole dried hips retain their integrity better during storage and can be ground later when needed.
4. Traditional Practices
Traditional herbalists sometimes prefer drying whole hips to preserve their natural structure and nutrient content. However, modern industrial processes frequently involve slicing or milling for efficiency.

Recommendation:

- If you prioritize speed and convenience, consider cutting or crushing the hips before drying.
- For maximum retention of active ingredients and traditional methods, opt to dry them whole.
In summary, while cutting or crushing will indeed speed up the drying process, it's important to weigh this against potential losses in nutritional value based on your end goal.

Making Syrup and Jam from Rosa canina subsp. inodora (Odorless Dog Rose): Role of Acidity

The Rosa canina subspecies inodora, commonly known as odorless dog rose, is characterized by its lack of strong floral scent compared to other rose species. This raises questions about the practicality and flavor profile when using this variety for making syrups or jams.

1. Is There a Point Without Characteristic Rose Aroma?

- Flavor Profile: While the absence of intense rose fragrance might seem like a drawback, it opens up new possibilities for blending with complementary flavors such as citrus, honey, or spices.
- Versatility: Odorless roses allow for more flexibility in creating unique blends that highlight other ingredients rather than being dominated by overpowering floral notes.

Generally speaking, rose hips from Rosa canina species are well - known for their exceptionally high levels of vitamin C, with typical values ranging between 150 - 650 mg per 100 grams of dried fruit. This places them significantly higher than many other fruits commonly consumed for their vitamin C content (such as citrus fruits like oranges).
While Rosa canina subsp. inodora may indeed have relatively high concentrations of vitamin C due to selective breeding for certain traits, there isn't definitive evidence that it universally contains more vitamin C than every other type of rose hip. For example, some studies suggest that other cultivars within the Rosa genus might also exhibit comparable or even slightly higher levels under optimal growing conditions.
In summary, while Rosa canina subsp. inodora is renowned for its favorable combination of high vitamin C content and reduced odors, its exact ranking relative to other rose hip types depends on various environmental and genetic variables. Further scientific research would be required to definitively establish if this particular subspecies consistently holds the highest vitamin C levels across all rose hip varieties.

Rosa canina subsp. inodora (also known as dog rose), particularly its fruit and flowers, has been traditionally used for various medicinal purposes due to its high content of vitamin C and other beneficial compounds such as antioxidants, flavonoids, and polyphenols.
- Official Medicine:
While Rosa canina (including subspecies like inodora) is not typically included in mainstream pharmaceutical preparations or officially recognized by all national drug regulatory authorities worldwide, it does have some level of recognition in certain countries' pharmacopoeias. For example, it may be listed in traditional herbal monographs or as an ingredient in over - the - counter supplements and food products.
- Folk Medicine:
The plant has a long history of use in folk medicine across Europe, including Russia, where it is commonly consumed as a tea or extract to boost immunity, treat colds, support digestion, and improve overall health. The absence of strong odors in Rosa canina subsp. inodora makes it more palatable compared to other varieties when used in teas or infusions.
In summary, while Rosa canina subsp. inodora finds limited use in official medicine, it remains widely utilized in folk medicine and natural health practices globally.

To extract the maximum amount of vitamin C and other beneficial compounds from Rosa canina subsp. inodora (without the typical rose hip odor), while brewing a tea, you should consider these factors:

1. Grinding

- Method: Grind dried or fresh rose hips into small pieces or powder form using a coffee grinder or mortar and pestle.
- Why it works: The smaller the particles, the greater the surface area exposed to hot water, allowing for more efficient extraction of vitamins and antioxidants.

2. Water Temperature

- Optimal range: Use boiling water (95 - 100°C / 203 - 212°F).
- Why it matters: Higher temperatures help dissolve soluble components like vitamin C, flavonoids, and polyphenols efficiently.

3. Brewing Time

- Duration: Steep for about 8 - 10 minutes.
- Why this is effective: Prolonged steeping allows sufficient time for the active ingredients to be fully extracted. However, avoid over - brewing as prolonged exposure may lead to bitterness and loss of volatile aromatic compounds.

Additional Tips for Enhanced Benefits:

- Pre - wash: Rinse the rose hips briefly with cold water before brewing to remove any dust or debris.
- Strain well: After brewing, strain out the pulp thoroughly to minimize any potential gritty texture.
- Storage: Store unused portions in an airtight container in the refrigerator to maintain freshness and potency.
By following these steps, you'll maximize the nutritional value of your Rosa canina subsp. inodora tea while minimizing any unpleasant odors.

Analysis and Answer

Taxonomic Information
- Species: Rosa canina (Dog rose)
- Subspecies: R. ca. cvv. subsp. inodora
- Common Name: Wild Rose Hip, specifically a variety known for its low aroma or odorless characteristic.

Considerations for Food Applications

1. Lack of Smell Impact on Taste
- The absence of strong odors does not necessarily mean that the taste is compromised.
- In fact, some varieties with less pronounced scents may have more subtle but still pleasant flavors.
- For example, Rosa canina subsp. inodora is often used for its milder flavor profile compared to other cultivars, which can be bitter or overly floral.
2. Applications in Paste/Puree/Kvass Production
- Paste and Purees: These products rely heavily on texture and sweetness rather than intense aromas. Rose hips are valued for their high vitamin C content and natural sweetness. A mild scent would allow the natural fruit sugars and acidity to shine through without overpowering the palate.
- Kvass: Kvass is traditionally made from fermented bread or fruits, and while it has a distinct sour - sweet flavor, adding rose hip juice or pulp enhances nutritional value without introducing an overwhelming fragrance. This makes it suitable for blending into kvass mixtures where the primary focus is on tangy and refreshing notes.
3. Nutritional Benefits
- One significant advantage of using Rosa canina subsp. inodora is its high concentration of vitamin C, which remains intact during processing when proper techniques are employed.
- Additionally, these hips contain antioxidants, polyphenols, and dietary fiber beneficial for health.
4. Conclusion
- The lack of strong odor in Rosa canina subsp. inodora does not negatively impact the taste of final food products like pastes, purees, or kvass. Instead, it allows the inherent sweetness and nutritional benefits to come forward, making it an ideal ingredient for those seeking a subtler yet nutrient - rich addition to their recipes.
