Begonia nantoensis NMWJ14461
1 packet of approximately 50+, naturally very small, hand pollinated, fresh seeds. A collection from Dasyueshan, Taichung, western Taiwan by Sue and Bleddyn Wynn-Jones with The Taiwan Natural Science Museum. A rhizomatous Begonia (thought to be a natural hybrid between Begonia palmata and B. chitoensis), which grows on shaded, moist, rocky slopes, and produces inflorescences of pink flowers in late summer to autumn held on seperate stems above the glossy, kidney-shaped foilage. Height 30 cm. Full to part shade in a cool, sheltered position in moist, humus rich, well-drained soil. Not tested for hardiness with us yet (though it could potentially be hardy to -5C to -8C with a deep mulch), so we would suggest growing it as a potted specimen in the garden and bringing it in before the first frosts.
I often get asked how to sow Begonia successfully. I find them easy but I've been doing it for some years - the main thing is warmth, light and humidity. I use a peat-free compost with added horticultural sand and surface sow the tiny seeds as they need light to germinate. I could go into more detail but space won't permit so here is a good, detailed link for those who would like to give it a try: www.begonias.org/greenhouse/…/brads_articles/seedgrowing.htm
