| Scientific Name: | Vachellia constricta (Benth.) Seigler & Ebinger | ||
| Common Name: | Whitethorn Acacia | ||
| Ecotype: | Madrean Archipelago | ||

Whitethorn acacia occurs from 2,500 to 5,000 feet in shallow caliche soil on dry slopes and lowlands. It flowers from May-November (Kearney and Peebles 1960). |
||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Propagule Collection: |
Collect the pods by hand when they have turned brown and crispy. Be sure to wear gloves and avoid the thorns! |
||
| Propagule Processing: |
Place pods in large plastic tub and stomp on them to break open the pods and allow the seeds to fall out. Sieve the seeds from the pod material. Clipper machine could also work well for separating pods from seeds by weight after the pods have been opened. In general, acacia seeds are durable and can maintain viability with no special storage requirements (Bonner and Karrfalt 2008). |
||
| Establishment Phase: |
It is necessary to scarify the hard coating on these seeds to improve germination rates (Cox et. al. 1993, Bonner and Karrfalt 2008). Scarification can be done by applying boiling water to the seeds and letting them soak for 3-24 hours. Mechanical scarification by sandpaper or nicking followed by hot water is also recommended (Conner and Karrfalt 2008). |
