Ohio Spiderwort: a pollinator-friendly native wildflower

A small fly-like bee was pollinating this flower.

Bluejacket or Ohio spiderwort (Tradescantia ohiensis) is native to most of Eastern North America and to most of Florida. It attracts pollinators, especially bees. Each day, one or two flowers bloom in each flower head. They open early in the morning and then wilt in the afternoon. Each flower head contains twenty or more flowers and new flower heads are formed throughout the long season from early spring to late fall. There is a long blooming season.

There are three other species of spiderworts native to Florida: hairy spiderwort (T. hirsutiflora), longleaf spiderwort (T. roseolens), and zigzag spiderwort (T. subaspera). But the bluejacket has the largest native range and is the one that's most readily available from the native trade.

Spiderworts are monocots and are in the Commelina family (Commelinaceae), which includes 36 genera world wide, but only five occur in Florida. "Spiderwort" refers to the sap which dries into web-like threads when a stem is cut.
