How Big Do Coral Bells Get?

Coral Bells attract many gardeners with the great variety of colors of their leaves. I couldn’t resist it either and have amassed a decent collection of different varieties of this plant. I am often asked about the size of Coral Bells and here I want to tell you about it.

On average, Coral Bells reach 15 inches tall and 30 inches wide. The size depends a lot on the variety and species. For example there are climbing varieties that can reach up to 40 inches in length.

In this article, I will tell you all I know about the size of the different species of Coral Bells. I will also share tips on how to increase or decrease the size of these plants.

Coral Bells Size

Most Coral Bells are shaped like a small rounded bush. The stems and leaf petioles are almost invisible and give the impression that it is just a cushion or mound of leaves. However, inside there is a thick, almost woody stem to which the leaf petioles are attached.

Over time, the stem divides into 2-3 or more stems. In addition, the stems are constantly growing upwards and should be shortened, because otherwise heuchera will have an unsightly appearance.

Type of variety Height Width
Big Coral bells 18 inches 30 inches
Medium Coral bells 14 inches 26 inches
Small Coral bells 12 inches 20 inches

Above I gave the height of Coral Bells without taking into account the peduncles. If the peduncles are taken into account, these plants can be much taller. Heuchera villosa, for example, can have flower stems 3 feet tall or even more.

There are also climbing varieties that do not grow in height at all, but only in length. For example, Plum Cascade can reach about 4 feet in length.

Сlimbing cultivars include:

  • Copper Cascade
  • Plum Cascade
  • Sugar and Spice
  • Pink Skyrocket
  • Crimson Cascade
  • Redstone Falls
  • Yellowstone Falls

In general, Coral Bells are not large plants. Hostas, hydrangeas and other popular garden plants are much larger.

Factors Influencing Size

The first thing that greatly affects the size of Coral Bells is the soil. In heavy clay soil it is difficult for the plants to develop a root system and therefore their size will increase slowly. Also clay soil is poor so heuchera may never reach their maximum size.

The second is the sun exposure. If Coral Bells grow in full sun their leaves will burn. As a result, the plant will not be able to form a lush shape and will grow slowly constantly recovering from sunburn.

The third is watering. Coral Bells can tolerate short periods of drought. However, that doesn’t mean it will thrive in dry soil. The plant will need sufficient water to reach the right size.

Maximizing Growth and Size

To maximize the size of Coral Bells you need to follow some growing rules. Let’s quickly go over them.

Before planting, improve the soil in your garden with organic matter. Just pour 1 bucket of compost or peat into the planting hole and mix it with the native soil. By planting the plant in such soil you will ensure rapid root development.

Water Coral Bells when the soil in the root zone is 1-2 inches dry. Watering is especially important during sunny and hot weather.

Plant heucheras in partial shade. Plants should get a few hours of direct sun in the morning or evening but in the middle for they should be in shade. Avoid planting them in full sun.

Fertilize them each spring with a slow-release fertilizer. Also water the plants 1-2 times a year with a liquid fertilizer.

Keep an eye on the health of Coral Bells. As soon as you see signs of disease or pests, take immediate action to get rid of it.

Conclusion

In conclusion, I would like to say that Coral Bells are compact plants that are perfect for a small flowerbed or even potted cultivation. With proper care they can turn into beautiful mounds of different colors and please you almost all year long.

That’s all I have, I hope this article was useful for you. I wish you good luck and successful gardening!
