Leaves

The leaves are dark-green with narrow to pointed tips that are shiny, and waxy. These plant leaves grow upward, bend over at the middle, and then downward which look like the spider’s bowed legs. 

Height

Spiderwort can grow up to 1- 3 feet tall and spread 1.00 to 1.50 feet. 

Fruit and Seeds

Fruit is a light-green rounded capsule, surrounded by three green bracts and containing dark gray seeds that mature 2-3 weeks (2)

How to propagate Spiderwort

This plant can be propagated through root division, cuttings, or seed. Spiderwort spreads quickly through underground roots which can be removed and make a new plant.

1. Propagation by seed

Sow the spiderwort seeds in early spring or late fall on soil and they will germinate in about 3-4 weeks. Once the seedlings are large enough to handle prick them out.  After that grow them into individual pots or outdoors. 

2. Propagation by stem cutting

The fleshy stems of this plant are very easy to propagate because they form roots at any node that is on the surface. To do so, choose the stem that is usually about two to three inches long with at least some internodes. Strip off the lower leaves and place them in a container with potting soil until roots develop (few weeks). This type of propagation will easily develop roots in summer or fall.
