• х Trichopsis cv. Chamäleon

Description: The name of this Trichocereus hybrid derives from the fact that the flowers discolour the on the second day. They are tender pastel red-orangish-pinkish on the first day while on the second they became clearly pastel-pink, throat is dark green, filaments fuchsia, anthers and stigma are a clear pastel. Growth is sturdy thick columnar type growth.

Cultivation and Propagation: Variegated cacti are regarded as choice and difficult in cultivation, but despite that many of them are relatively easy to grow. But be aware that they cannot tolerate prolonged exposure to direct sun light (especially during the hottest summer days), so grow them in half-shade or under filtered sun. They are sometime seen as grafted plants, but some of this colourful plants (those with some chlorophyll) are able to grow on their own roots and are priced by collectors.
Soil: Use mineral well-permeable substratum with little organic matter (peat, humus).
Watering: Water sparingly from March till October, and keep perfectly dry in winter, at temperatures from 5 to 15 degrees centigrade. (In general these plants are more tender and cannot endure freezing temperatures). In the rest period no high atmospheric humidity!!
Propagation: By seeds, grafting or cutting. Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue in relation to each other. A most common way way to cultivate this partially de-coloured cultivars is to graft them onto another cactus which has chlorophyll and which will provide sugar to the mutant scion. The chlorophyll containing bottom part of the graft, called the stock, can be any number of different columnar cactus species.
Remarks: Seeds from variegated parents often give raise to some variegated seedlings too.
