Seedling & Establishment
3-4 monthsFine, thread-like cotyledons emerge; seedlings develop silvery-green needle-like foliage. Growth is initially slow.
Keep soil consistently moist but not wet during germination (60-90 days); provide protection from extreme heat. Transition to drier conditions gradually after 2-3 months.
Vegetative Growth
12-18 monthsPlant develops bushy form with fine-textured, silvery-green foliage. Stems become semi-woody. Growth is moderate and somewhat spreading.
Minimal watering once established; allow soil to dry between waterings. No fertilizer needed; avoid nitrogen-rich amendments. Prune in early spring to maintain form and encourage branching.
Pre-Flowering
4-6 weeksBuds form at branch tips in late July through August. Foliage remains healthy and dense; plant prepares for prolific flower production.
Continue drought conditions; supplemental water only during severe drought stress. Avoid pruning to preserve flowering branches.
Flowering & Pollination
8-12 weeksAbundant bright yellow flowers appear in dense clusters from late August through November. Blooms attract bees, butterflies, and other pollinators. Flowers are highly fragrant.
Do not deadhead unless managing seed production. Continue minimal watering. Avoid pesticide use to protect pollinators.
Seed Development & Dormancy
4-6 monthsFlowers fade to seed heads in late fall and winter. Foliage may take on reddish or bronze tones. Plant becomes semi-dormant.
Leave seed heads for wildlife food source and self-seeding if desired. No supplemental water needed. Prune dead or damaged wood in early spring before new growth.

Common Pests
-
Rarely problematic in natural desert conditions; spray with water if infestation occurs; provide adequate spacing for air circulation
-
Not typically harmful; natural predators usually control populations; avoid broad-spectrum insecticides
-
Occurs only in overly moist conditions; improve air circulation and reduce watering; fungicidal spray if severe
