We saw this very hardy Aralia growing in small cracks of big granite boulders around Killarney, and I was thinking, again, how many wonderful, garden-worthy, but under-utilized native plants we have around. The purplish black fruits resemble a bit the elder fruits, hence the other popular name: dwarf elder.
It has shiny, compound leaves with the stem base covered by bristly hairs. White-cream flowers appear in June-July in round umbels on stalks that diverge at the end of the stems. The fruits are maturing gradually, at times having on the same plant berries in various colours from green to red, and black. Also, the inflorescences stalks turn red, making a nice contrast with the black fruits in the fall.
Germination: best if sown outdoors in late fall or after a period of cold-moist stratification in the fridge before spring sowing.
