T. zebrina has drooping stems and 3-inch-long,
1 1/2-inch-wide leaves; the silvery white top surfaces have a broad central
stripe and narrow green edges; the undersides are purplish red. The two-colored
wandering Jew, T. zebrina 'Discolor', has a bronze-green central stripe
with a purplish tinge. The four-colored wandering Jew, T. zebrina 'Quadricolor',
has leaves irregularly striped with shades of green, purple, red, pink
and white; the edges and undersides are purplish red. All types are excellent
in both pots and hanging baskets.
HOW TO GROW. Inch plants and wandering
Jews do best in bright indirect or curtain-filtered sunlight; if only artificial
light is available, provide at least 400 foot-candles. In less light the
plants survive, but the leaves of variegated types turn almost all green.
Night temperatures of 50° to 55° and day temperatures of 68°
to 72° are ideal. Let the soil become moderately dry between thorough
waterings. Feed established plants every two months with standard house-plant
fertilizer diluted to half the minimum strength recommended on the label;
wait three or four months before feeding newly purchased or potted plants.
If the plants are grown in plain water, add a few drops of liquid fertilizer
every month or so. Repot overcrowded plants at any season, using a mixture
of 1 part loam, 1 part peat moss or leaf mold and 1 part sharp sand; to
each gallon pailful of this mixture add 1 1/2 teaspoons of 20 per cent
superphosphate, 1 tablespoon of ground limestone and 2 teaspoons of 5-10-5
fertilizer. Or use a packaged general-purpose potting soil. Propagate at
any season from stem cuttings. Generally pest free.
