This is a native riparian plant that does well in regular garden conditions in shade or partial sun. If you live an area with dry summers, Twinberry will need weekly water. I've read that it can become drought-tolerant, but I imagine that it'll go stress deciduous under such conditions. (Mine looks beat-up if the soil is allowed to dry out in the summer.) The form that is sold up here has yellow flowers, and I'm aware that there are variants with pink and reddish-yellow flowers. Mine has not yet produced berries, but they're apparently popular with the birds. Fall foliage is a pleasant yellow. This is a nice small-ish shrub for a shady area where you want a little bit of green.
