One of our all time favorite Begonias that is surprsingly hardy when established. Soft green angel wing shaped leaves fan out and are the great backdrop to masses of small, single soft orange flowers. Blooms continuously from late June to frost. Rich soil that drains in part shade to high overhead shade is ideal. Protect from blasting sun. Exquisite container subject that mixes well with other plants and adds a saucy orange to shade plantings. In the ground this plant requires a little more care. Rich soil in protected location – under shrubs or near the house and a little patience. Returns slowly in the ground- not usually showing its face until Mothers Day or later. Once growth proceeds it goes quickly. Nice self cleaning blooming plant. Spent flowers simple tumble off the plant and are replaced by a massive continual display. To 8″ x 8″ and wider with time. Winter deciduous. For plants growing in containers you’ll need to protect the container from excess wet and freezing. The best way to overwinter it is to put it under an eave or an unheated garage or greenhouse. Add organic fertilizer with the onset of growth. Lovely perennial that we adore at Xera.
To be honest we had quite a bit of employee pushback when we said we were growing a Bergenia- I’m sure they immediately thought of that hulking, horrible looking, weevil notched ground cover with clouds of pepto pink flowers in winter/spring. That old horribly abused plant is definitely not this. HUGE round leaves have light fur on the reverse and make a wonderful statement in part shade to full sun (with water). In very early spring this cultivar named by Richie Steffan of the Elizabeth Miller Garden in Seattle- sends up wide inflorescences of pink tinted white flowers. Best with overhead protection of trees to ensure a late freeze doesn’t damage the flowers. This is a DECIDUOUS species and doesn’t seem to be root weevil food or suffer a bad looking period. New leaves ensure freshness all season. Give it a LOT of room to spread. Tropical looking foliage adds bold dimension to borders, woodlands. Regular summer water in well drained rich soil. Thanks Richie.
