PLACEMENT & CULTIVATION
Angel's trumpet carefully pleated buds swirl open at dusk, the freshly opened flowers releasing a sweet fragrance that attracts nighttime moths. During the day, bumblebees pry open these buds to rob it of its pollen. Datura is a bountiful patio plant that transforms at night into a luminous beacon in moon and tropical themed gardens. It thrives in warm summer weather and should be grown in a warm, protected spot in northern gardens to enhance its growth and night fragrance. Caution: all parts are toxic. Be aware of its poisonous qualities when placing in the garden.
Water regularly—about 1" or so per week. While somewhat drought tolerant, greater moisture availability will increase blooms.
Prefers more acidic soils but will tolerate neutral settings.
Mix in an organic granular fertilizer that is high in phosphorus to promote flowering.
Diseases & Pests:
Spider mites may be an issue—hose down plants with a heavy stream of water regularly until the pest is gone. May also be damaged by Hummingbird Moth caterpillars (hornworms). Monitor plants July-August and remove caterpillars promptly.
