Growing directions
Plant fans with the crown about 1 in deep, spreading roots outward over a small mound of soil in the hole. Water thoroughly after planting and keep consistently moist the first season. Divide overcrowded clumps every 4–5 years in early spring or late summer when bloom quality declines. Removing spent scapes after all buds have opened keeps the planting tidy.
Source and local conditions
Typical planning ranges from OpenPlantDB (CC0). Cultivar, climate, season and growing method can change these values. Confirm the seed label and local guidance before planting.
