The Wandering Jew plant (Tradescantia zebrina) is famous for its stunning purple-and-green foliage, but achieving those vibrant colors depends entirely on getting the light conditions right. Too much sun burns the leaves, while too little causes leggy growth and faded colors.

1. Ideal Light Conditions

Perfect Balance:

• • Bright, indirect light (6–8 hours daily)

• • Avoid direct midday sun (causes leaf scorch)

Light Intensity Guide:

Expert Source: The Royal Horticultural Society recommends filtered sunlight for Tradescantia species to maintain leaf variegation.

2. Signs of Too Much/Little Light

Too Much Light

• • Bleached or brown patches on leaves

• • Crispy, curled edges

• • Soil dries too quickly

Too Little Light

• • Leggy stems with wide gaps between leaves

• • Faded or green-dominant leaves (loss of purple)

• • Slowed growth

Quick Fix:

• • Move to a brighter spot if leggy.

• • Use sheer curtains if leaves are scorched.

3. Best Indoor Locations 

Perfect Spots:

• • East-facing windowsill (gentle morning sun)

• • West-facing window (afternoon light filtered by curtains)

• • Near a south window (3–4 ft away)

Avoid:

• • Direct south-facing windows in summer.

• • Dark corners (causes etiolation).

Pro Tip: Rotate the plant weekly for even growth.

4. Outdoor Light Requirements

USDA Zones 9–11: Can grow outdoors year-round.

• • Partial shade (dappled sunlight under trees)

• • Morning sun + afternoon shade is ideal.

Warning:

• • Full sun in hot climates burns leaves (University of Florida IFAS notes Tradescantia prefers 30–50% shade outdoors).

5. Artificial Light Options

For low-light homes/offices:

• • LED grow lights (12–14 inches above plant)

• • 12–14 hours daily timer setting

Best Bulbs:

• • Full-spectrum LEDs (5000–6500K color temperature)

• • Avoid incandescent (too hot)

NASA Study: Tradescantia grows well under artificial light in controlled environments (Source).

6. Seasonal Light Adjustments

• • Spring/Summer: Move away from intense midday sun.

• • Fall/Winter: Place near brightest window (less intense sun).

Winter Tip: Supplement with grow lights if days are short.

7. FAQs

Q: Can Wandering Jew grow in low light?
A: Yes, but it becomes leggy and loses color. Bright indirect light is best.

Q: Why are my plant’s leaves turning green?
A: Not enough light! Move to a brighter spot to restore purple hues.

Q: Can it handle direct sun?
A: Morning sun only. Afternoon sun scorches leaves.
