Begonia maculata 'Medora' Morphology
About Begonia maculata 'Medora'
Begonia maculata 'Medora' is a named cane begonia cultivar prized for unusually large, prominent white spotting, bolder and more strongly contrasted than the plain species' finer silver dots, set against dark green leaves with strongly contrasting burgundy undersides. Like the other named cultivars here, it is not a chimeric sport, so cuttings reproduce the pattern reliably, but it circulates mainly among collectors rather than through general retail.

Before You Buy
Shared checklist for Begonia maculata and its cultivated forms
- Check for powdery mildew (a white dusty coating on leaf surfaces, especially in dry conditions); it spreads rapidly between plants
- Inspect for mealybugs at leaf axils and the underside of stems where they hide in white cottony deposits
- Rhizome begonias should show firm, healthy rhizome tissue; avoid plants with soft, discoloured rhizomes
- Most begonias ship well as leaf cuttings; if buying a cutting, ensure it has a healthy petiole and no signs of rot at the cut end
- For variegated or cultivar forms, confirm the cutting or plant shows the named form's characteristic variegation/leaf pattern; heavily reverted (all-green) growth is worth considerably less
Propagation Guide
How to Propagate Begonia maculata 'Medora'
Shared across every form of Begonia maculata — see this form's own Morphology for variegation-specific propagation notes.
3-5 months
Cultivar character is preserved through vegetative cuttings
Most rhizomatous begonias root readily from leaf sections or petiole cuttings placed on moist substrate. Keep warm and humid until plantlets emerge at leaf margins. Variegated and cultivar forms of the species should be propagated from cuttings taken at a node that shows the desired variegation or leaf character; see that form's own page for details.
Care Guide
Begonia maculata 'Medora' Care Guide & Growing Conditions
General care shared across all forms of Begonia maculata — cultivated forms may need brighter light or higher humidity than the plain species; check this form's Quick Facts above.
Light, well-draining mix: 50% perlite, 30% potting compost, 20% orchid bark. Begonias are susceptible to root rot, so excellent drainage is essential.
Allow the top half of the substrate to dry between waterings. Water at the base; wet leaves invite fungal problems. Reduce in winter.
50–70%. More tolerant of average indoor humidity than tropical aroids, but consistent moisture prevents crispy leaf margins. Heavily variegated forms often want the higher end of this range; check that form's Quick Facts.
Balanced liquid fertiliser at quarter strength every 2–3 weeks during the growing season. Do not feed in winter.
Every 12–18 months in spring. Begonias like shallow, wide pots that suit rhizomatous growth. Don't bury the rhizome.
Common Problems
Powdery mildew
Poor air circulation combined with high humidity
Improve airflow; avoid wetting leaves; treat with a dilute bicarbonate of soda spray
Botrytis (grey mould)
Overwatering, dead leaves left on plant, poor air circulation
Remove dead foliage promptly; increase airflow; reduce watering
Leggy stems
Insufficient light
Move to a brighter position; begonias need good indirect light to maintain compact growth
