| Family Scientific Name: | Lamiaceae | ||
|---|---|---|---|
| Family Common Name: | Mint | ||
| Scientific Name: | Monardella sheltonii | ||
| Common Name: | Shelton's coyote-mint (may hybridize with other species of Monardella) | ||
| Ecotype: | Seed was collected form 3 locations within eastern Tehama County, California: along Lower and Upper Dye Creek at The Nature Conservancy's Dye Creek Preserve, along Antelope Creek and from the Hog's Back ridge. Seed was also collected from The Natur | ||
| General Distribution: | California and Oregon. Rocky clearings, montane forest, oak woodland, chaparral, and serpentine below 2000 meters (Hickman 1993). | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | Potted nursery stock | ||
| Time To Grow: | 0 | ||
| Target Specifications: | First year seedling approximately 4 cm tall with vigorous, fibrous and rhizomatous root system. | ||
| Propagule Collection: | Relatively clean seed may be shaken from whole fruiting heads collected from mid to late summer. | ||
| Propagule Processing: | Propagule processing is not generally necessary, though tiny seed is difficult to separate from any chaff collected with the seed. Approximately 1,500-2,000 seeds per gram, depending on individual, population, year and cleanliness of seed. | ||
| Pre-Planting Treatments: | None, though clean dry seed was placed in dry, cold storage following collection and prior to sowing. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
During November 2004, seed was directly sown into 1.5" deep flats containing a potting mixture of approximately 1:1:1:2 sand:pumice:peat moss:fir bark mixture. Flats were placed in an outdoor cold frame from late-fall though spring. Most seedlings were transplanted into various sized pots ranging form D-pots to 3x4" plastic containers (some seedlings were not transplanted) using the same potting mixture. Active growth occurs well into summer, though summer watering may result in fungal growth and rot. Better growth may be obtainined during the first year by avoiding transplanting (seed directly into larger containers rather than flats). Based on results of direct seeding in the field, better above and below gound growth may be obtained by planting in native soil (e.g.loam) rather than potting soil. Loam appears to have lower fluctuations in moisture and temperature which may stress seedlings and reduce growth during the first year. Growth from seed to dormant seedling follows the first fall rains through the spring-summer dry-down. Under good growing conditions, this species may flower within the first year. | ||
| Establishment Phase: | Initial germination was observed within 2 weeks. Highly variable germination rates were observed for individuals from different populations. Observed germination rates were as follows: Seed sown in an outdoor cold frame - 15% (Vina Plains), 25% (Hogback) and 30% (Dye Creek); Seed cold-stored at approximately 44F in moist vermiculite - 70% (Cone Grove Park), 68% (Dye Creek), 34% (Hogback), 33% (Lower Dye Creek), and 53% (Vina Plains). Robust seedlings approximately 4 cm tall with vigorous fibrous root system may be established the first summer (within 7-8 months). | ||
| Length of Establishment Phase: | Transplantable sprouts were established within approximately 3-4 weeks. | ||
| Active Growth Phase: | Active growth was observed within 2 weeks after seeding in November (i.e. germination) and continued until early summer (June). | ||
| Length of Active Growth Phase: | 7-9 months (fall to late summer). Older plants may not initiate above-ground growth until spring. | ||
| Other Comments: | Flowering: Mid May - September (Oswald and Ahart 2002); Seed collection: June-September. Partial funding for this project was made available by the California State University Agricultural Research Initiative (ARI). | ||
