ISI 2018-4. Echinocereus pentalophus (De Candolle) Lemaire

This slender-stemmed, five-ribbed species is prized for its large, showy flowers. These blooms can be over 10 cm diameter and are normally flashy magenta with a white throat. They also feature the green stigmas that are characteristic of many species in the genus. White-flowered forms of typically more colorful species may seem like a compromise for those addicted to color. In this case, however, the flowers are so grand and the white is of such a pure, virginal quality offset by the dark green of the stigma lobes, that this is a very desirable variant. It came to us via the Atlanta Botanical Garden from the Dr. J. G. Barrows collection ex the Echinocereus Reference Collection in England. Rooted cuts of HBG 134250, $8.
