The Star Begonia
Begonia heracleifolia, known as the star begonia or star leaf begonia, is a rhizomatous begonia grown for its patterned foliage. It is at home in a conservatory, greenhouse, or as a houseplant, forming a low, mat-forming clump rather than a tall specimen.

Mexican to Honduran Roots
This species is native to a stretch running from Mexico down through Belize, Guatemala, El Salvador, and into Honduras, and it has also found its way into parts of the Caribbean. In the wild it behaves as an epiphyte, settling into the seasonally dry tropical forests of that region. People there have put it to use as a medicine and a food as well as an ornamental.

Light, Soil, and Rest
Give this begonia partial shade at a north, west, or east aspect, in a sheltered spot, and it settles well. It prefers a loamy soil kept moist but well-drained, with a neutral pH. After flowering it may go dormant, and at that point watering should be cut back and the plant kept on the dry side until new growth returns.

By Seed or Division
The star begonia can be raised from seed, or increased by division carried out in spring.

Star-Patterned Leaves
The palmate leaves give the plant its common name, marked with white principal veins, a green inner zone, and a darker outline that reads like a star from above. Turn a leaf over and the underside is burgundy, while the leaf stems themselves carry red spots. When it flowers, pale pink or white blooms rise in upright clusters above the foliage.

Watch For These Visitors
Caterpillars, mealybugs, mites, glasshouse thrips, vine weevil, and aphids may all take an interest in this begonia, so it is worth checking leaves and stems regularly for early signs of them.

Rot and Mildew Risks
Grey mould and powdery mildew can trouble this species, along with stem rot and rhizome rot, most of which point back to conditions that are too wet or too still. Keeping the soil moist but genuinely well-drained, and easing off water during its post-flowering dormancy, helps keep these at bay.

Simple Tidying
Maintenance mostly comes down to removing dead or damaged leaves and spent flower spikes as they appear, keeping the clump looking fresh.
