Seedling
10-14 daysTiny plants with 2-4 true leaves, fragile and pale green. Growth is slow initially.
Maintain 70-75°F soil temperature, provide bright indirect light, keep soil lightly moist. Avoid overwatering which causes damping off.
Transplant/Vegetative
10-20 daysPlants develop deeper green coloring, multiple branching points, and stronger stems. Root system expands rapidly in containers.
Transition to stronger light gradually if grown indoors. Begin fertilizing with diluted liquid fertilizer every 2 weeks. Pinch stem tips to encourage bushier growth if needed.
Bud Formation
10-15 daysFirst flower buds appear at stem tips; plant continues branching. Foliage becomes fuller and more compact.
Maintain consistent moisture and temperatures 65-75°F. Increase fertilizer to weekly applications. Harden off if transitioning outdoors.
Flowering
8-12 weeks or until frostAbundant deep purple blooms appear continuously. Plant reaches full mounding shape (8-12 inches tall and wide).
Maintain regular watering and fertilizing weekly with balanced or slightly higher phosphorus fertilizer. Remove any yellow leaves. Deadheading is minimal but occasional removal improves appearance.
Late Season/Decline
4-8 weeks until frost or end of seasonFlowering may slow in late summer heat but rebounds with cooler fall temperatures. Plant becomes woody and less compact.
Continue watering and fertilizing. In zones 9-11, cut back by 1/3 in fall to rejuvenate for second season. In cooler zones, enjoy until frost kills plant.
