Plant Details

A little known treasure. Stunning gentian-blue flowers are produced on short stems, daily from midsummer onwards. The dazzling flowers fade by late afternoon but are replaced by fresh ones each morning.

Works well in the border dotted among other low plants, on-masse as ground cover, or planted within a wildflower meadow scheme. Also looks wonderful in a pot or container. 

Native to Arizona, Colorado, New Mexico, Texas, and northern Mexico. We have found it quite hardy (it came through the 'Beast from the East' in 2017/2018 here) once established. Can self-seed, making stunning drifts with time.

Height and spread: 25cm x 25cm

Myth and Folklore

An infusion of the plant was used by Keres people as a strengthener for weakened tuberculosis patients. The Ramah Navajo give an infusion to livestock as an aphrodisiac.

Common name(s): Bird-bill Day Flower; Widow's Tears.

Syn: Commelina coelestis

All our plants are supplied in 9x10cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. We do not sell 'plug plants' because those need to be grown on before planting. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow everything we sell ourselves, in our nursery in the Buckinghamshire countryside.
