Germination & Seedling
7-14 days to germination, 3-4 weeks to transplant sizeTiny seedlings emerge with first true leaves appearing. Very delicate and slow-growing at first.

Flowering
6-12 weeks (often until frost if well-maintained)Abundant double or semi-double blueberry-purple flowers with fringed petals appear continuously in clusters atop the foliage.
Deadhead spent flowers regularly to promote continuous blooming throughout the season. Feed with balanced or slightly phosphorus-rich fertilizer every 2-3 weeks.
Peak Bloom & Summer Performance
4-8 weeks depending on climatePlant reaches maximum flower production with dense, colorful blooms covering the compact mound.
In hot climates (zone 8+), provide afternoon shade to prevent petal fading. Continue deadheading. Water more frequently during heat waves.
Decline & End of Season
Until first frost (annuals) or into winter (perennials in warm zones)Flowering may slow in intense heat or as season progresses; growth may become leggy or sparse.
Cut plants back by one-third to rejuvenate and encourage a second flush of flowers in fall. In mild climates, may overwinter and rebloom spring.
