Blue Spiderwort

Blue Spiderwort (Commelina) - A charming old garden plant with flowers of a fine blue. C. Coelestis delights in light warm soils. The roots are fleshy, and in some districts it is well to cover them with coal ashes on the approach of winter. In cold, wet districts the roots may be lifted and stored in dry leaf-mould. On some warm or stony soils, and in districts near the sea where light soil prevails, it grows like a weed. It is so fine in color that a group or small bed is always welcome. There is a white form.
