Seedling
2-3 weeksTiny seedlings emerge with two cotyledons; plants are delicate and slow-growing initially
Keep soil warm (70-75°F) and consistently moist. Provide bright light. Thin seedlings if direct-seeding. Use well-draining seed-starting mix.
Vegetative Growth
3-4 weeksPlant develops true leaves and stems begin to branch; growth accelerates as temperatures warm
Maintain warm conditions (65-75°F minimum). Begin light fertilizing every 2 weeks. Pinch tips early to encourage bushier, more cascading growth.
Flowering Initiation
2-3 weeksPlant produces first flower buds at branch tips; stem length extends as cascade habit develops
Continue regular watering and begin weekly fertilizing with balanced or bloom-promoting fertilizer. Ensure full sun exposure for maximum flower production.
Peak Blooming
8-16 weeks (spring to first frost)Abundant white flowers with darker centers continuously appear from late spring through frost; cascading stems reach full mature length
Water consistently as flowering increases water demand. Fertilize weekly with diluted liquid fertilizer. Deadheading is minimal but removing spent flower clusters keeps plant tidy.
Decline/Dormancy
Variable (season-dependent)Flowering slows as temperatures drop in fall and winter; plant may lose vigor in cold climates
In warm zones, plant continues blooming. In cool zones, treat as annual and remove after frost, or bring indoors before first frost to overwinter in warm, bright location.
