| Family Scientific Name: | Ranunculaceae | ||
|---|---|---|---|
| Family Common Name: | Buttercup Family | ||
| Scientific Name: | Clematis drummondii Torr. & A. Gray | ||
| Common Name: | old man’s beard | ||
| Ecotype: | Madrean Archipelago | ||
| General Distribution: |
Typically grows along washes and streams from southern California to Texas and into Mexico (Flora of North America Editorial Committee 1993+). Flowers March-September and found in elevations below 4,000 ft with other shrubs (Kearney and Peebles 1960). |
||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Propagule Collection: | Seeds can be collected when fruits are brown and soft white plume-like styles are effortlessly removed from the plant with seeds attached. Pinch seed plumes with your fingers to collect them. | ||
| Propagule Processing: |
Achenes can be removed from plumes by shaking dry material and allowing mature seeds to fall (Bonner and Karrfalt 2008). This method has not yet been tested by manual authors. Little information on storage of C. drummondii is available; however western virgin’s-bower has maintained viability for 2 years (Bonner and Karrfalt 2008). Orthodox storage is assumed. |
||
| Establishment Phase: |
The scientific literature generally agrees that Clematis drummondii requires cold stratification to achieve maximum germination results (Ajilvsgi 2013). To stratify, place seeds in a moist media 1-5°C for 60-180 days (Ajilvsgi 2013, Bonner and Karrfalt 2008). Following proper stratification, Clematis drummondii can reach 74% germination when subsequently placed in sand flats or germinators at 20°C and 30°C during the night and day respectively for 40 days (Bonner and Karrfalt 2008). Other sources suggest that Clematis drummondii propagation by seed is relatively simple and may not require prior stratification (Lady Bird Johnson Wildflower Center). |
