Fringed begonia tubers
Fringed begonias are defined by the finely cut, ruffled edges of their petals, which give the flowers a more textured outline than classic double forms. The blooms are still full and substantial, but the fringed margins soften their shape and introduce extra movement as the petals unfold. Colours range from clear single shades to stronger bicolours, making these tuberous fimbriata begonias especially useful where flower form matters as much as colour.
Grow fringed begonia tubers in pots, containers or sheltered borders where the flowers can be seen at close range. Start the tubers frost free in spring, then move them outside once cold nights have passed. Bright shade or filtered light suits them well, together with fertile, free-draining compost that stays evenly moist through active growth. In containers, regular feeding will help support the succession of large, detailed blooms through summer.
Their value is in the surface detail. Place one fringed begonia variety in a substantial pot and the cut petal edges become part of the overall form, or combine several colours and let the shared ruffled outline hold the planting together. Deadheading fimbriata begonias encourages further buds into autumn, while healthy tubers can be lifted and stored dry and frost free once the growing season ends.
