Growing Cardinal Vaughan Peonies

Cardinal Vaughan peonies have their own unique planting needs, and it’s important to understand their needs before deciding to plant them.

Outdoor

Cardinal Vaughan peonies can grow up to 7 feet tall and can spread out up to 5 feet. Their size makes them perfect for planting along fences and they bloom during the summer. They are low maintenance and can last more than 20 years.

It’s important to plant this type of peony in the spring and early fall, so the roots have enough time to settle and establish themselves. Keep in mind where you want to plant the peonies, as they don’t do well with transplanting and they need to be in an area where the water can drain properly.

Growing Zones and Weather

Cardinal Vaughan peonies can tolerate growing zones 5 to 8 and are part sun to full sun. This type of peony might not assume its full blooming potential if it doesn’t have the right amount of sunlight.

Soil

Fertilizer with phosphorous is great for encouraging good root development in young plants, so it’s ideal to add fertilizer of your choice. The Cardinal Vaughan peony can tolerate sandy loam soil to clay loam soil with a pH range of 5.5 to 7.5.

Water

Cardinal Vaughan peonies need to be watered with about an inch of water per week, possibly more in situations of intense heat. You can also water them when the top 3 inches of their soil is dry.

Step-By-Step Planting Guide

Cardinal Vaughan peonies have their own guide on how they should be planted, as most plants do. Below are instructions on how to plant Cardinal Vaughan peony roots and seeds.

Bare Root Cardinal Vaughan Peonies

  1. Dig a hole in the ground 10 inches deep and the same length across. Their roots require a lot of room to grow.
  2. Add in a fertilizer of your choice that contains phosphorus, because that’s what young plants need.
  3. Mound soil up in the center of the hole so that it’s only about 2 or 3 inches deep. Set the root clump on top so that the eyes face upward.
  4. Fill the rest of the hole and lightly pack down the soil. Water by sprinkling the area, careful not to flood.

Potted Cardinal Vaughan Peonies

  1. Prepare a large hole with a fertilizer of your choice with phosphorous.
  2. Remove the peony from the pot and slightly loosen the root ball. In the hole, set it at the same height it was in the pot.
  3. Fill the rest of the hole and lightly pack down the soil. Thoroughly water the planting site.
