Basic Information
Common Name: Hairy Dasynotus
Scientific Name: Dasynotus daubenmirei
Native Habitat: Western Montana, USA
History / Discovery / Cultivator
Dasynotus daubenmirei, commonly known as Hairy Dasynotus, is a relatively obscure plant primarily found in a limited geographical range within western Montana. Its discovery and classification are attributed to botanists who meticulously explored the flora of the Rocky Mountains. The plant belongs to the Boraginaceae family, also known as the borage or forget-me-not family. The “Dasynotus” genus itself suggests a characteristic feature: “dasys” from Greek meaning “hairy” and “notos” meaning “back,” likely referring to the hairy backs of the leaves or some other hairy feature of the plant. The species epithet, “daubenmirei,” honors Rexford Daubenmire, a highly influential American plant ecologist.
Rexford Daubenmire’s work significantly contributed to our understanding of plant communities and ecological succession in the Northwestern United States.
Daubenmire’s ecological studies and detailed vegetation mapping provided a foundation for understanding the specific habitat preferences and ecological role of species like Dasynotus daubenmirei. The plant’s discovery is likely tied to floristic surveys aimed at documenting the biodiversity of Montana’s unique environments. While the exact circumstances surrounding its initial collection and formal description might be somewhat vague, the plant’s limited distribution means that any botanical exploration within its range could potentially have led to its discovery.
Because Hairy Dasynotus is not a widely cultivated species, specific details regarding its cultivation history are limited. It isn’t typically found in mainstream horticulture. Its conservation status and habitat requirements suggest it might require specialized conditions that are not easily replicated in a garden setting. The plant likely thrives in specific soil compositions, elevation ranges, and moisture levels characteristic of its native Montana habitat. Therefore, propagation and widespread cultivation may prove challenging. While dedicated native plant enthusiasts or botanical gardens focused on preserving regional flora might attempt cultivation, detailed information about its cultivation methods is scarce.
Its origins are deeply rooted in the unique ecological conditions of western Montana. The plant is adapted to the specific climate and soil types present in that region, likely coevolving with other native plant species. Because of its limited geographical range, Dasynotus daubenmirei serves as an indicator species for specific ecological conditions within its Montana habitat. Understanding its ecological requirements is thus crucial for conservation efforts aimed at preserving the biodiversity of the region. The history of this plant, though not widely documented, underscores the importance of botanical exploration and ecological research in identifying and preserving the unique flora of specific geographical areas.
Plant Care Summary

| Water | Moderate | Allow soil to dry slightly between waterings; avoid overwatering. |
| Humidity | Low | Prefers dry air; high humidity can lead to fungal issues. |
| Temp. Range | Cool to moderate | Tolerates a wide range, but prefers moderate temperatures. |
| Soil Type | Well-draining, rocky | Needs good drainage to prevent root rot; amend with gravel or sand. |
| Fertilizer | Light feeding | Fertilize sparingly in spring and early summer with a balanced fertilizer. |
| Toxicity | Unknown | Insufficient data available regarding its toxicity. Exercise caution. |
Botanical Insights
Adaptations
Dasynotus daubenmirei exhibits several adaptations to its native environment in western Montana. Its hairy leaves are likely an adaptation to reduce water loss through transpiration, particularly important in dry, exposed habitats. These hairs also provide some protection against intense sunlight and can deter herbivores. Its ability to thrive in rocky, well-drained soils suggests adaptations for nutrient uptake in challenging conditions. Its growth cycle is also likely synchronized with the short growing season of its high-altitude habitat.
Propagation Methods
Due to its rarity and limited cultivation, specific propagation methods for Dasynotus daubenmirei are not widely documented. However, based on general knowledge of plants in the Boraginaceae family, potential propagation methods might include seed propagation, division (if the plant forms clumps), or potentially stem cuttings. Seed propagation would require collecting mature seeds and providing appropriate stratification conditions to break dormancy. Division could be attempted on mature plants with multiple stems, carefully separating the roots. The success of stem cuttings is unknown and would likely require experimenting with different rooting hormones and propagation media.
Toxicology
Because it is not widely grown or researched, the toxicity of Dasynotus daubenmirei is not well-documented. It is recommended to exercise caution. Contacting local poison control or veterinary services if ingestion is suspected by either human or pet would be the best course of action.
Common Problems
Pests:
- Aphids
- Spider mites
- Mealybugs
Diseases:
- Root rot (if overwatered)
- Powdery mildew (in humid conditions)
- Fungal leaf spots
Other:
- Leaf yellowing (may indicate nutrient deficiency or overwatering)
- Stunted growth (may indicate insufficient sunlight or poor soil)
- Wilting (may indicate underwatering or root damage)
Rarity & Value
Rarity:
Dasynotus daubenmirei is considered relatively rare due to its limited geographical distribution, primarily restricted to specific habitats in western Montana. Its specific habitat requirements and potential challenges in propagation also contribute to its rarity in cultivation. Limited natural habitat and specific soil requirements make widespread establishment less likely.
Value:
The market value of Dasynotus daubenmirei, if available, would likely be driven by its rarity and appeal to collectors of native or unusual plants. Plants originating from reputable sources with documented provenance would likely command a higher value. Size and maturity of the plant might also affect its value. The current interest in native plant species might contribute to a niche demand, affecting potential market value.
