Size & Growth

Growing as a house plant the potted pinstripe plant reaches about 1′ or 2′ feet high and wide.

The leaves are colorful and beautifully patterned. Typically, younger leaves are green on the top with striking bright pink lines located between the lateral veins.

The undersides of leaves are purple.

As plants mature, the lines lose their pink color and become white.

Fully mature, flowering plants usually do not have lined leaves. Alternately, the white lines may disappear, and yellowish green brush patterns may take their place.

Mature plants may also lose the purple hue of the leaves’ undersides, which may transition to a deep green.
