Altitudes of C & S. America
Grown for their beautiful and unusual flowers.
They can be rather difficult to grow. However, most of them are cool growing, and need only the usual orchid cultivation of coarse compost. They need plenty of water in the summer with a little light shade. In temperate climates, they need to be grown in greenhouses. They can be grown in pots but also on slabs of bark. Weak foliar feeds can be added to the sprays.
Propagate from older, leafless pseudobulbs which can be removed for replanting, or from new growth which may appear from the bottom of the plant.
Prone to red spider mites, aphids and mealy bugs.
