Begonia sutherlandii

We have a range of Begonias, mostly of the cane variety (having stiff upright stems supporting often heavily and attractively spotted leaves). Rhizomatous cultivars are shorter and bushier, the leaves arising from rhizomes (fat more or less horizontal stems which lie close to the ground). The leaves of most  Begonias are typically lop-sided, and are red on the underside, which adds to the leaf coloration especially when back-lit. The pink, red or white flowers are small but often produced in large bunches. All need shade from hot sun & make excellent houseplants. Grow in a loam-based compost for stability, with added grit or bark to make a free draining mix. They need to be kept on the dry side when growth slows in winter, especially if the leaves fall.  They need a minimum 10 °C to maintain growth, but we have found that most plants will survive near freezing temperatures, though most will lose their leaves. Many of our cane Begonias survived a couple of degrees of frost in our greenhouse.
