Bud burst usually occurs in late March or early April but may occur as early as late February. Restricted growth continues until May. Accelerated growth occurs from May until early or mid-August. Populations at higher elevations flower in July whereas those from low elevation Mojave Desert populations do not begin flowering until mid-October. Seed dissemination starts before all flowers are fully mature. The rate of dissemination is affected by weather conditions, including wind and moisture.
Fruit typically matures earlier on plants experiencing little competition.
