PLACEMENT & CULTIVATION
Sweet William 'Hollandia Purple Crown' is a radiant biennial that is commonly grown as an annual. It is known for attracting butterflies and bees, and its flowers are deer-resistant. Sweet William is a popular choice for border and cutting gardens, and the edible petals are a colorful addition to salads or as a decorative garnish on plates. Mulch during its first winter, being sure to keep the crowns uncovered. Severe cold or saturated winter soil may lead to dieback.
Watering Details:
About 1" per week. While somewhat drought tolerant, greater moisture availability will increase blooms.
