Identifying and Growing 'Betulia' Begonias

"Betunia" is likely 'Betulia' — a new begonia that blooms continuously without day-length sensitivity and holds a neat shape with minimal pinching. Overwinter indoors in east/west window, water when dry, fertilize from January. Propagate by February cuttings. Repot in January into larger pot with fresh soil.

Unheated greenhouses are risky — begonias die below freezing and struggle under 40°F.
