Growth Stages

1

Establishment

2-3 months

Young plant with minimal foliage; thin stems developing serpentine pattern

Water lightly 1-2 times per week during first 2-3 months; protect from extreme heat if in full sun; avoid overwatering which causes root rot

2

Early Growth

3-6 months

Stem elongation and branching; feathery foliage becoming more prominent; distinctive twisted form emerging

Reduce watering frequency; allow brief dry periods; no fertilizing needed; minimal pruning

3

Vegetative Development

6-12 months

Fuller branching structure; more pronounced serpentine shape; dense fine foliage along stems

Taper to nearly drought watering; optional light pruning to enhance architectural form; no supplemental fertilizer required

4

Flowering

2-3 months (seasonal)

Small yellow flowers appear along stem tips and branch ends; blooming period may occur spring to early summer

Maintain established drought watering pattern; do not prune during flowering to preserve blooms; flowers attract pollinators

Mature Shrub

Ongoing, 2+ years

Fully developed serpentine form with established branching; occasional yellow flowers; dense feathery foliage year-round

Minimal maintenance; water only during extreme droughts; minimal to no pruning needed; highly ornamental architectural form
