Paeonia Tenuifolia - Intense Crimson Fernleaf Peony

Paeonia tenuifolia is a perennial flower that is better known as the fern leaf peony. This variety of peony has a crimson color to it that is similar to what you'd see with heirloom red roses. It is a plant that will typically be one to two feet tall early in the growing season. Paeonia tenuifolia blooms earlier than other varieties of peonies and can flower all summer, into autumn, but will sometimes go dormant in mid-summer.

Paeonia tenuifolia can be grown in zones 4 through 7 and will begin blooming in June.

Paeonia tenuifolia is the perfect ornamental flower

Paeonia tenuifolia has a few flowers that are excellent for growing as a companion. These flowers include similarly intense colored rose varieties and colors (per your choice), Jackman's Clematis, Carnations, and Chrysanthemums. Even other Paeonia tenuifolia, such as the pink shades of Rosea and Rosea Plena, are good too The choice is up to you though. Many perennials that enjoy full sun to partial shade, like the fern leaf peony does, make for a great companion flower.

Paeonia tenuifolia care

In early spring you should start watering the flowers if there isn't enough rainfall to do the watering for you. In late spring it's best to remove flower heads that are dead or look like they are dying. You should also remove fallen petals and flower heads from around the flowering plant. In the summer, it is also best to keep the flowers watered if need be.

When the flower has died back in the fall it is best to cut back the foliage of the plant and remove from the flower bed. This is to prevent pests from surviving over the winter. It may sound extreme but you should cut them back to ground level.
