It can be grown in a container year round with an ever changing backdrop of annuals. The yellow flowers attract pollinators during the summer. The brilliant orange pumpkin like berries attract birds through the winter, All the while the semi-evergreen foliage changes from a very dark green to a rusty color after the first hard frost.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
