Water regularly to establish deep roots. Mulch lightly with pine needles or sand. Avoid transplanting in hot weather.
Vegetative Growth
Months 2-8 of first yearPlant develops bushy branching structure; foliage deepens to dark purple-bronze as it matures

Flowering
8-12 weeks during peak bloomSmall, deep purple-magenta bell-shaped flowers appear in dense spikes along branch tips, creating a showy display

Winter Dormancy
December-February (4-6 weeks depending on climate)Growth slows dramatically; foliage darkens further to deep burgundy or black-purple, intensifying the winter interest
