Marsh Marigold Information
Swamp or marsh marigolds are famous for their glossy, heart-shaped leaves and colorful flowers. In favorable conditions, these small plants can spread and create large groups. They usually grow in wet places like swamps, by ditches, near rivers, and in low areas.
Like many similar-looking plants, swamp marigolds can be harmful if eaten. Let’s take a closer look at some other plants often confused with swamp marigolds and learn how to tell them apart.
Plants that Resemble Marsh Marigold
1. Hypoxis hirsuta
Another native plant, Hypoxis hirsuta, is a small flower that often grows in fields and near partially wooded areas. Its short, grass-like leaves are easy to overlook until the plant starts flowering. When it blooms, it produces attractive yellow star-shaped flowers that pollinators love. While it can spread in favorable conditions, it’s not usually considered invasive.
2. Ficaria verna
While swamp marigold plants can spread, they’re typically not seen as invasive in many areas. However, the same can’t be said for Ficaria verna, also known as lesser celandine. Once established, lesser celandine spreads rapidly, forming dense mats that can outcompete native plants. Although its leaves look similar to marsh marigolds, the flowers are slightly different. Experts recommend avoiding planting lesser celandine in gardens as it can easily escape and take over areas beyond borders and beds.
3. Ranunculus acris
Both Ranunculus acris and marsh marigold are classified as true buttercup species. However, there are several ways to tell them apart. While both have bright yellow flowers, their appearance and growth habits differ significantly. Meadow buttercup, also known as acris, forms clumps of serrated, fern-like leaves. In spring, it produces flowers on tall, slender stems, distinct from marsh marigolds. These toxic plants are sometimes invasive and may need chemical or manual methods to manage their spread.
4. Geum radiatum
Geum radiatum, also called Appalachian avens, is native to specific parts of the United States. These plants mainly grow near cliffs or rocky areas on mountaintops. Unfortunately, they’ve become increasingly scarce in recent years and are now considered endangered in many regions.
5. Chrysogonum virginianum
Chrysogonum virginianum, also called “green and gold,” is a perennial plant native to the United States, able to withstand USDA zones 5-9. It’s often used as ground cover in home gardens. These plants do best in well-draining soil and prefer shade during the hottest times of the day. In their natural habitat, you can find green and gold growing in clearings or near wooded areas.
