About This Plant

Callisetmon seiberi (River Bot), 'River Bot', is valued for its garden character and seasonal interest in PNW landscapes.

Callisetmon seiberi is an ornamental shrub valued for its seasonal interest and the role it plays in the garden landscape.

Full sun to part shade suits this species. Plant in moist, well-drained soil. Hardy USDA Zone 5 to 9. Provide consistent moisture during establishment. Watch for general pest pressures common to the region.

Care Notes

Plant in well-drained, sandy or loam soil; poor drainage is the primary cause of decline. Tolerates dry conditions once established; water deeply but infrequently during the first growing season to encourage deep roots. Minimal pruning needed; remove dead or crossing branches after flowering. Suited to coastal conditions including salt spray and wind exposure.
