Establishment
4-8 weeksYoung shrub with sparse foliage establishing its root system
Water regularly (weekly) for first 4-6 weeks after planting. Mulch lightly around base but keep away from stem. Avoid overwatering.
Vegetative Growth
Year 1-2Shrub develops dense, fine-textured foliage. Leaves are small, narrow, and gray-green. Little to no flowering yet.
Reduce watering frequency as plant establishes. Prune lightly to shape if desired. Provide excellent drainage; do not allow standing water.
Flowering
6-8 weeks (late July-September in most zones)Delicate white, pale pink, or bicolor flowers appear in clusters along branches. Flowers are tubular and attract hummingbirds and bees.
Flowering typically occurs in late summer/early fall, often triggered by warm summer rains. No deadheading necessary. Avoid fertilizing, which promotes foliage over flowers.
Dormancy/Winter Rest
3-4 months (November-February)In cooler zones, foliage may thin or plant may lose leaves. In warm zones, plant remains partially evergreen with minimal growth.
No water supplementation needed in dormancy unless extreme drought occurs. Do not prune or fertilize. Apply frost cloth in zone 7 if hard freeze is forecasted.
