Establishment
4-8 weeksYoung plant with minimal foliage, establishing root system
Water regularly for first 4-8 weeks to establish roots. Avoid overwatering. Mulch lightly with gravel to retain soil moisture and prevent fungal issues.
Vegetative Growth
2-4 monthsPlant develops bushy form with small, narrow gray-green leaves; minimal flowers
Reduce watering frequency as plant matures. Prune lightly to encourage bushiness if desired. Provide excellent drainage to prevent root rot.
Flowering
6-12 weeks (can rebloom with summer moisture)Abundant pure white tubular flowers appear in leaf axils; typically triggered by monsoon rains or summer warmth
Flowering is rain-triggered in desert climates. Minimize water to avoid excessive vegetative growth that shades flowers. Flowers attract hummingbirds and pollinators.
Dormancy/Decline
3-4 months (winter or dry season)Foliage may drop or thin during winter or drought periods; plant becomes semi-deciduous
Do not water during dormancy. Avoid pruning severely in fall. Light pruning to remove dead branches is acceptable.
