Tradescantia zebrina is a colourful trailing plant that looks effective when trailing from a windowsill or even an indoor hanging basket. Known as the wandering Jew or the inch plant (because it grows quickly), it has striking foliage and is very easy to maintain.
Tradescantia is also known as the spider lily. The foliage is stripy, with a strong green stripe and margin against cream. Underneath, the leaves are purple, creating great contrast. The leaves feel velvety to the touch.
