Description

Downy Thorn Apple is a tender herbaceous perennial, often grown as an annual, with a 3 foot spread. In its native environment of the Southwestern United States, it is usually found in sandy or gravelly dry open places. The plant displays 7 to 8 inch cream, pink, and lavender tubular flowers, which open in the evening, but only last to late afternoon of the next day. Flowers will bloom intermittently from mid-summer to frost. It is planted throughout the world as an ornamental for its attractive large leaves, flowers, and distinctive thorny fruit. However, several locations now consider the plant invasive. Flowers are followed by downy spherical fruit covered with stiff spines, hence the common name of downy thorn apple. Plants belong to the nightshade family and all parts are extremely toxic.

Downy Thorn Apple prefers warm temperatures, well-drained, rich, moist soil, and full to partial sun with regular moisture. It will tolerate alkaline soil, but does not do well in full shade. It does tolerate sandy soil and is winter hardy to USDA Zone 9-10. Most plantings of Downy Thorn Apple are nursery plants; however, you can start seeds indoors about 6 to 8 weeks before the last spring frost and set plants out after that date. Plants tend to sprawl, and should be spaced about 3 feet apart or staked and supported. Deadheading flowers is not necessary and self-seeding may occur. Container plants can be cut back and overwintered indoors in a sunny window.

Diseases, Insect Pests, and Other Plant Problems: Extremely susceptible to the viruses that afflict the potato family (Solanaceae). Downy Thorn Apple should not be grown near potatoes or tomatoes.
