Description
Tradescantia sillamontana is a low-growing plant with fleshy stems that hold dull olive-green to gray-green leaves, sometimes blushed purple and covered with cobwebby silver-white hairs. It grows up to 18 inches (45 cm) tall, and it is one of the most succulent and most attractive species of the genus Tradescantia. Leaves are arranged in 2 ranks and up to 2 inches (5 cm) long. The new stems are also covered with silver-white hairs, so the plant appears quite silver. Magenta flowers have three petals crowded into the terminal leaf axils. They appear in summer.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Growing Tradescantia is easy, and you will find the plants to be quite resilient. These plants typically grow in moist, well-drained, and acidic (pH 5 to 6) soil. Tradescantias do best in partial shade but will do equally well in sunny areas as long as the soil is kept moist.
You can grow Tradescantia indoors too, as long as suitable conditions are given. Provide the plant with either a soilless mix or loam-based potting compost and keep it in bright filtered light. You should also pinch out the growing tips to encourage bushier growth.
Allow it to spend warm spring and summer days outdoors, if feasible. Water moderately during its active growth and apply a balanced liquid fertilizer every four weeks. Water sparingly in winter.
These plants like to be kept fairly moist, so water regularly, especially when growing them in containers. Cutting the plants back once flowering has ceased can often promote a second bloom and help prevent re-seeding. Cut the stems back about 8 to 12 inches (20 to 30 cm) from the ground.
