Which daylilies are invasive?

Answered by Stephen Mosley

There are several daylilies that have been identified as invasive in certain locations. One example is the yellow daylily, also known as Hemerocallis lilioasphodelus. This particular species has been found to be invasive in scattered locations in the eastern United States.

When it comes to identifying invasive daylilies, it is important to note that not all varieties are considered invasive. In fact, many daylilies are well-behaved garden plants that pose no threat to their surroundings. However, there are a few species and cultivars that have the potential to spread rapidly and outcompete native vegetation.

The yellow daylily, or H. lilioasphodelus, is one such species that has been known to exhibit invasive tendencies. It has been reported to naturalize and spread beyond its intended cultivation in certain areas. This can be a concern for native plant communities, as invasive daylilies can outcompete and displace native species, leading to a loss of biodiversity.

In terms of the edibility of daylilies, it is worth mentioning that the buds and flowers of daylilies are indeed edible and can be used in culinary preparations. They have a unique flavor that is often described as sweet-spicy or peppery. Many people enjoy adding daylily buds or flowers to salads, stir-fries, or even using them as a garnish.

However, it is important to exercise caution when consuming daylilies, as not all varieties are safe for consumption. Some daylilies, particularly those in the Hemerocallis fulva species, may cause allergic reactions or digestive issues in certain individuals. It is essential to properly identify the specific variety of daylily before consuming it.

While daylilies are generally beloved for their beautiful blooms and versatility in the garden, it is crucial to be aware of certain species that can exhibit invasive tendencies. The yellow daylily (H. lilioasphodelus) is one such example that has been identified as invasive in scattered locations in the eastern U.S. When it comes to consuming daylilies, it is important to exercise caution and ensure that the specific variety is safe for consumption.
