Genus of over 100 species of fibrous or tuberous perennials and mat-forming annuals. A
native plant to Africa, Asia, North America, and South America. The lance-shaped leaves are
borne on the thick stems alternately. The flowers are three petaled, emerge one at a time from
the terminal bracts, and last the duration of one day. This is where the name dayflower
originated. Each plant has multiple flowering bracts, which give way to hundreds of flowers
each season.

Commelina (Dayflower) Growing Tips
|
|
- Plant in a well-drained soil that has been incorporated with organic matter, and is within
a pH range of 6.0-7.0.
- This plant can easily be cultivated outside its hardiness range. To do so, lift tubers
before the first heavy frost, pack in sawdust, and store in a frost free area. When, the
soil temperatures warm up in spring plant the tubers back outside.
- When, growing in containers incorporate sand into the planting medium for proper
drainage.
