Cryptanthus (Cryptanthus), zebra and colored rosettes: culture, maintenance
The cryptanthe (Cryptonthus) is a houseplant in our latitudes, native to eastern Brazil where it grows on the ground or on rocks in dry woods, up to 1600m altitude. It is afraid of cold and thrives at least 15°C. Its root system is very low.
The evergreen leaves form a flattened, flared, star-shaped rosette, without a stem (acaule). The ribbon-like leaves, 10 to 20cm long, have wavy edges and are often attractively tinged with cream, pink, silvery bronze on a green background.
In the center of each rosette, corymbs of small, tubular, starry, white, sometimes fragrant flowers rise in summer.
According to the species of Cryptonthussuckers form in the axils of the leaves, or at the base of the plant, which are easily removed.
All cryptanthes are part of indoor plants with decorative leaves that stand out: many amateurs looking for quite original plants are interested in Cryptonthus. In addition, their ease of cultivation as well as their relatively modest size make them additional assets in small residences and for beginners trying their hand at growing green plants.
