Solanum schlechtendalianum: complete guide

Overview

Solanum schlechtendalianum, known as Riedle's nightshade, is an impressive tropical climbing plant or shrub ranging from Mexico to South America and into Trinidad. This member of the Solanaceae family captivates with beautiful flowers and remarkable fruits. The plant grows larger than many other Solanum species and requires adequate space.

Appearance & Bloom

This species grows as a semi-woody climbing plant or shrub with long, slender stems. The leaves are oblong-ovate with a soft texture. The flowers are bright purple to violet and appear in small clusters along the stems. The fruits are spherical, initially green and ripening to yellow or orange. These attractive fruits persist on the plant for extended periods. The plant has a somewhat wild and exotic appearance.

Ideal Location

Riedle's nightshade thrives in bright, indirect light. Illumination of at least 5000 lux is ideal. Do not place this plant in direct afternoon sun, but ensure bright window placement. In summer, place the plant outdoors in a sheltered, partially shaded spot. Avoid full sun during hot seasons.

Soil

The plant grows well in fertile, well-draining potting soil. A mixture of peat-based compost with 30 percent perlite and some bark chips promotes excellent drainage. The plant prefers neutral to slightly acidic soil. With extended cultivation, soil nutrients may decline; supplementation with compost helps.

Watering

Keep soil nicely moist but not waterlogged during the growing season (spring to autumn). In winter, significantly reduce watering. The plant tolerates some drought but develops better with consistent moisture. Misting with water in dry conditions stimulates growth.

Pruning

Pruning is important to maintain this vigorous-growing plant's shape. Pruning can occur nearly year-round. Pruning promotes branching. For pot cultivation, prune to desired height and form. For climbing applications, regularly pinch lateral shoots.

Maintenance Calendar

March-May: Prune, repot into fresh soil, begin feeding. June-August: Feed regularly (every 2 to 3 weeks), mist in dry conditions. September-October: Gradually reduce feeding. November-February: Minimal watering, cool placement without drafts, minimal feeding.

Winter Hardiness

This tropical plant cannot tolerate frost and must overwinter indoors at temperatures of at least 50-59 degrees Fahrenheit. In very warm, tropical climates, the plant can grow outdoors. Water very sparingly during winter rest. Place in light without direct sun.

Companion Plants

Combine with other tropical exotics such as various Passiflora species. For pot combinations, add trailing green plants for textural contrast. In the garden (warm climates), train along a support with other climbers.
