| Scientific Name: | Dalea pulchra Gentry | ||
| Common Name: | Santa Catalina Prairie Clover | ||
| Ecotype: | Madrean Archipelago | ||
| General Distribution: |
Found in uplands commonly on rocky slopes or mountain foothills from 2500-5000 ft in southern Arizona and Mexico (Kearney and Peebles 1960). It’s early flowering time makes it a beneficial plant for enhancing pollinator habitat in the region. |

| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Propagule Collection: |
Populations have been collected from in late spring (mid-late May). When collecting D. pulchra seeds begin by removing terminal inflorescence spikes that have few remaining flowers on them. Run your hand along the spike to allow the seed to fall into your hand. |
||
| Propagule Processing: |
First, remove large sticks and twigs with hands or tweezers.Using hands or sandpaper, push remaining material around in a sieve to separate the seed from the bracts. Once separated, the fluffy bracts and the seed can fall through the sieve. Air winnowing out the fluffy bracts from the seed is fairly easy due to their large difference in weight and texture. Remove remaining plant material by hand if necessary. Orthodox storage is assumed. |
||
| Establishment Phase: |
The Borderlands Restoration nursery staff has seen germination rates increase from 2% to roughly 30-35% with light scarification with sandpaper on the seed coat. Further experiments are recommended using more intensive physical scarification and cold stratification. Little information is available about this species. |
