Plant Overview

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.

The foliage of these plants is primarily on their flowering stems, so at certain times of the year, you may receive plants with little or no foliage. This is completely normal and nothing to worry about.

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 9cm 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. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant.
The majority of our plants are grown outdoors. This means that they follow their natural growth patterns and are ready to plant at any time of the year. If you order the plants in winter, they are likely to be dormant and died back to ground level, ready to shoot again in spring - just like the herbaceous perennials in your own garden. Very occasionally, in winter and early spring, we may indicate on the packing slip that a plant needs to be hardened off before planting out. This will be because it has just come out of a polytunnel. If you have any questions about our plants or growing methods, please feel free to drop us an email.
We grow most of what we sell ourselves, in our nursery in the Buckinghamshire countryside. Our prices include VAT at 20%.
Please note: We do our best to provide acurate photographs of the plants we sell, but colours display differently on different screens, printers and in different light and we cannot guarantee that what you are seeing on your screen, or on the plant label provided, will exactly match the plant when it flowers in your garden.
