Growing tradescantia (also known as spiderwort) might cause flashbacks to the 1970s but it still merits its popularity as a houseplant or a groundcover. This tough tropical plant can have trailing or upright stems and colorful foliage. Depending on the species, tradescantias are typically purple and often variegated with silvers, greens, creams, even pinks, and occasionally gold. Many of the light-foliage varieties have dark purple undersides, which creates a dramatic effect.

Though not the main reason they are grown, many varieties produce small flowers that grace the attractive foliage. Most often these three-petal blossoms are pink, purple, or white and typically at the stem tips. However, in some species these flowers are at the base of the leaves in oysterlike clusters, hence the common name of oyster plant.

Where to Plant  Tradescantia

If you're planting tradescantia indoors, put it near a window that gets bright, indirect sunlight. If your tradescantia is planted outside, you'll need to check which variety you have before deciding where it will go. For the most part, these plants do best in full sun (except where it's very hot in the summer), but do well in shade, also.

Tradescantia Care Tips

Members of the Tradescantia genus are some of the simplest plants to grow, requiring little maintenance. They're also super easy to propagate and makes a wonderful pass-along plant for friends.


Tradescantias are quite tolerant of different sun exposures. For the best coloring, plant in full sun, which generates the most blossoms possible. Inside, they tolerate just about any light level, but in shade, they may become washed-out looking. Too little sun causes leggy growth, meaning the stems grow in a stretched out way with few leaves on them. Indoor plants will benefit from spending some warm, sunny days outside in summer.

Soil and Water

Provide tradescantia with general-purpose potting mix and good drainage. When planted in the garden, most tradescantias prefer growing in moist soil with a pH pf 5 or 6. In warmer climates, they work beautifully as groundcover. Many of the trailing varieties form dense mats and will root everywhere the plants touch the ground.

Because of their fleshy stems, tradescantias can withstand an occasional drought. If they wilt, they'll usually perk up quickly after a good watering. In containers, water these plants regularly to keep the soil consistently moist.

Temperature and Humidity

Tradescantia will be happy in the same type of environment most people like. An indoor temperature of between 60-80°F is best for them. If tradescantia is grown outdoors, bring them in before the first frost, which can kill them.


You don't have to feed Tradescantia, but they'll grow more robustly if you do give them a little fertilizer. Only add fertilizer to Tradescantia in the spring and summer. Use liquid fertilizer at half strength each month, or use a controlled-release fertilizer at planting time.


Though it may not be necessary, an occasional pruning and grooming of tradescantias will make for a more appealing plant. Some types tend to lose their lower leaves, creating unattractive naked stems. This is easily remedied by pinching the growing tips to encourage more branching.

Potting and Repotting Tradescantia

Choose a pot with drainage holes and use fresh potting mix when you are planting tradescantia in a container. These plants don't need repotting very often, but if you notice roots poking out of drainage holes, choose a slightly larger container to move your plant into. The best time to repot tradescantia is in the spring.

Pests and Problems

The biggest pest for tradescantia is aphids, which can be washed away with a strong spray of water. Other than that, there aren't a lot of issues that affect these plants. Keep an eye on their leaves for any signs of bugs, but diseases are rare for this genus.

How to Propagate Tradescantia

Tradescantia can be propagated by division or from cuttings. Older plants with lots of growth are perfect for starting new plants from cuttings. This is easily done by snipping off a few inches of stem, removing the lower leaves (leave a few at the tip), and sticking the cutting in water or damp soil. When starting cuttings in water, once roots emerge, transplant to evenly moist soil. Cuttings in summer and fall will respond best to replanting.
