Sorbaria sorbifolia 'Sem' is an RHS Award of Garden Merit winner and a small to medium-sized shrub with fluffy panicles of white flowers in July to August. Foliage are pinnate, with a fresh green colouring, sometimes with a gold hue, and having flashes of red in the new growth. Stems can be a rich red. Ideal for the city or town garden, for container growing, or as an attractive, light and airy flowering shrub in the border. Has a suckering habit, so remove shoots to stop spreading.
