Dumb Cane 'Sublime' Overview

Dieffenbachia 'Sublime' is a stunning cultivar in the arum family, Araceae. It has large, showy foliage with bold variegation. The green and white colours form a mosaic-like pattern across the leaves and create a beautiful camouflage-like appearance. This highly decorative cultivar strongly resembles the cultivar Dumb Cane 'Reflector'. It is tender and thus needs to be grown indoors or under glass in temperate regions. Over time this sparsely branching perennial forms an upright cane, similar to that of palm species. Flowers are rarely seen in cultivation, however when provided with good growing conditions, the resulting bloom is typical of the Araceae family, that is, enclosed within a fleshy, green-white spathe structure. The species and genus this cultivar was bred from originated from Central and South America, this tender plant makes a nice potted houseplant, or plant in a position of partial shade, in moist, well-draining soil, in a location free of frosts for optimal growth.
