Tradescantia

Tradescantia,Inch Plant, Wandering Jew (older common name), Wandering Dude, Spiderwort

Tradescantia is a genus of extremely popular, fast-growing perennial herbs native to the Americas. They are characterized by fleshy, trailing, or clumping stems adorned with lance-shaped leaves that often exhibit striking variegation in shades of purple, pink, green, white, and silver. They are highly valued for their vibrant color and ease of care, making them excellent hanging basket or tabletop plants. They produce small, three-petaled flowers, usually pink or white. Popular cultivated varieties include T. zebrina (purple and silver stripes), T. fluminensis 'Variegata', and T. nanouk.

Care Guide

LIGHT

  • Requires bright, indirect light to maintain vibrant color and compact growth.
  • East or West-facing windows are ideal.
  • Insufficient light causes stretching (legginess) and the colorful variegation (purple, pink, white) to fade to green.
  • A few hours of direct morning sun is usually tolerated and beneficial for color.

WATER

  • Prefers the soil to dry out mostly between waterings.
  • Allow the top half of the soil to dry out completely before soaking thoroughly.
  • The fleshy stems store water, making them susceptible to overwatering, which causes mushy stems and rot.
  • Underwatering causes the leaves to curl, dry, and stems to become brittle.

SOIL

  • Needs a light, well-draining, standard indoor potting mix.
  • A blend of potting soil with added perlite or coarse sand helps prevent compaction and root rot.

GROWTH HABIT

  • Ideal conditions: Consistent warmth (65-75F) and average indoor humidity.
  • Growth rate & size: Growth rate is very fast. It is a vigorous, trailing vine that can quickly grow long and sprawling.

PROPAGATING

  • Propagates extremely easily from stem cuttings with just one or two nodes.
  • Cuttings root readily in water or moist soil within days.
  • Cuttings are best taken when pruning to keep the mother plant bushy.

PRUNING

  • Pruning is essential and frequent to maintain a full, bushy look, as the base of the plant naturally becomes sparse over time.
  • Pinch or cut back the longest, sparsest stems to encourage new growth from the roots and to use the cuttings to replant on top of the soil.
  • Remove old, damaged, or fully dried-out leaves.

REPOTTING

  • Repot when the plant is root-bound, typically every 1-2 years due to its fast growth.
  • Repot in spring or early summer.
  • Due to their tendency to become sparse at the top, many people prefer to start a new plant annually from cuttings in fresh soil rather than repotting an old one.

FERTILIZING

  • Feed regularly during the spring and summer growing season (monthly).
  • Use a balanced liquid houseplant fertilizer diluted to half strength.
  • Stop fertilizing in the fall and winter.

FLOWERING

  • Produces small, three-petaled flowers, usually pink, white, or blue, that appear at the tips of the stems.
  • Flowers are short-lived and generally considered secondary to the colorful foliage.

TOXICITY

  • Mildly toxic to humans and pets. Can cause skin irritation (dermatitis) upon contact and mild stomach upset if ingested.

PRO TIPS

  • Constantly propagate and replant cuttings into the original pot's soil surface to keep the plant's crown dense and full.
  • If the color is dull, move it to a location with more intense indirect light.
  • Look out for small, black/brown spots on the leaves, which can indicate overwatering or fungal issues.

Variability in Care

Most varieties of this plant follow the standard care above, but some require adjustments based on their variegation.

Purple/Zebrina Types

Examples: Tradescantia zebrina (silver and purple stripes)

  • Requires bright light to maintain the vibrant purple coloration and striping.
  • The purple pigment offers some protection from direct light, making it slightly more tolerant of morning sun.

Pink/White/Cream Variegation

Examples: Tradescantia fluminensis 'Variegata', T. 'Nanouk'

  • These varieties have less chlorophyll and are slower growing.
  • The white and pink areas are prone to browning if the humidity is too low or if they receive too much direct sun.
  • Require consistent bright light to prevent the white/pink areas from reverting to green.

Green/Non-Variegated Types

Examples: Tradescantia pallida 'Purple Heart' (thick, all-purple leaves)

  • These are generally the hardiest and most sun-tolerant.
  • The deep purple coloration on 'Purple Heart' is intensified by direct, bright light.
