Actaea matsumurae 'Frau Herms'

About this cultivar:

Actaea matsumurae 'Frau Herms' is a green-leaved form of Actea that produces white flowers and then lime-green seedheads. Similar to 'White Pearl', there is not much info on this one to be found. I believe the species was first described by Takenoshin Nakai in honour of Jinzo Matsumura, an early 20th century Japanese professor of botany.

About this genus:

Actaea are herbaceous perennials, many of which were known as Circimifuga from 1732 (when John Bartram discovered the plant) until 2000 when DNA evidence discovered Circimifuga were also Actaea. Whatever you call them, Actaea have a majestic frame - tall and graceful - with dark straight stems. The leaves are often matt shades of the dark bronze-black-brown, but can also be glossy or green.

Depending on the cultivar the fragrant flowers can be delicate white, cream or pale pink, and are tightly packed on dreamy spikes. This foliage, flower, and fragrance combination undoubtedly makes it a favorite in our garden at Ballyrobert and we think it should be in every garden.

You're often told Actaea prefer part shade or full shade and thrive in cooler, moist areas. However we grow one in an old bath in the middle of our yard! (I think by definition the climate in the British Isles is never full-sun). If too dry their leaves scorch, if too sunny the leaves bleach. Difficult to propagate since they don't like being disturbed and are quite slow growing. The simplex species tends to flower in later Autumn. The Atropurpurea Group typically have purple to bronze tinted foliage

In the garden Actaea tend to be used for their foliage and look great mixed with other foliage plants such as ferns (Dryopteris, Polystichum, and Polypodium), Heucheras, and glossier grasses such as Hakonechloa. Flower-wise Actaea also work well with Anemones, Fuchsias, and even some Hydrangeas.
