Tree peonies are actually shrubs, with permanent, woody stems and larger flowers than the herbaceous types. Small-flowered P. delavayi makes a good foliage plant for the back of a border.
These mainly rounded shrubs, wider than they are tall, have handsome leaves showcasing the gorgeous flowers. P. delavayi is upright and vase-shaped. Tree peonies lose their leaves in winter.
A sunny or lightly shaded position in fertile soil that drains easily is ideal. Feeding and mulching well just as the plants come into growth in spring is beneficial.
These plants dislike strong winds and severe cold that can damage the young foliage and flower buds.

If necessary, you can prune plants lightly after they have finished flowering. P. delavayi is easily grown from seed.
