Is alum root the same as coral bells? This is a question that many gardeners may wonder about. The answer is both yes and no. Let me explain further.
Alum root and coral bells are both common names for plants in the genus Heuchera. However, there is a subtle difference between the two terms. Alum root is a broader term that encompasses all species within the Heuchera genus, whereas coral bells specifically refers to certain species within the genus.
Heuchera, or alum root, is a diverse genus consisting of about 55 species, although the exact number may vary depending on different sources. These plants are native to North America and are known for their evergreen to semi-evergreen nature. They are herbaceous perennials, meaning they die back to the ground in winter but regrow from the base each spring. This characteristic makes them particularly popular in perennial gardens.
Coral bells, on the other hand, are a subset of Heuchera species that have been specifically bred for their colorful and often ornamental foliage. The term “coral bells” is generally used to describe Heuchera cultivars with vibrant red, orange, or pink leaves. These cultivars are highly valued for their visual appeal and are often used as focal points or accents in garden designs.
One of the most interesting facts about coral bells is that they played a significant role in plant exploration history. They were among the first North American plants exported back to Europe in the 1600s by early American explorers. This historical significance adds to their allure for many gardeners.
In terms of cultivation and care, alum root and coral bells have similar requirements. They prefer well-drained soil, and most species thrive in partially shaded areas, although some can tolerate full sun. Regular watering is essential, especially during dry periods. As with any perennial, proper mulching and regular fertilization can help maintain the health and vigor of the plants.
When it comes to propagation, both alum root and coral bells can be propagated by division or from seed. Division involves separating the plant into smaller clumps and replanting them, while growing from seed requires a bit more patience and expertise. Whichever method you choose, it’s important to ensure the new plants have adequate space to grow and thrive.
In my personal experience, I have had the pleasure of growing both alum root and coral bells in my garden. I find their foliage incredibly attractive, and they add a touch of color and texture to my landscape. The different cultivars of coral bells have been particularly intriguing, as each one offers its own unique combination of leaf colors and patterns.
While alum root and coral bells are closely related, they are not exactly the same. Alum root is a broader term encompassing all species within the Heuchera genus, whereas coral bells specifically refer to certain cultivars with colorful foliage. Both types of plants are highly valued for their beauty and versatility in garden design, and they can be successfully grown with proper care and attention.
