Paeonia tenuifolia

Paeonia tenuifolia

This herbaceous species is known as the fernleaf peony for its finely divided foliage and low, mounded habit.

It stands out for early crimson flowers above feathery leaves.

Plants perform best in full sun and very well‑drained soil.

Bloom is typically mid spring in much of North America.

Clumps are durable but resent frequent division.

Foliage may go summer‑dormant in heat or drought.

Fragrance is light on most forms.
