Columnea calotricha has interesting orange hairs all over the plant. The flowers are modest in size, but the clusters, taken with the fuzzy calyces and attractive orange and yellow color, provide a nice display. The flowers on Mr. Stewart’s plant have never opened completely — he assumes that he is not providing quite the right conditions.

The species comes from relatively low altitudes in French Guiana and other hot places, and probably requires very warm and humid conditions. A photo of a plant found in nature can be seen here. A leaf and stem are illustrated here. Also known as Trichantha calotricha.
