Unlike most ecosystems, in serpentine barrens, there is less plant growth closer to a stream, due to toxic minerals in the water. Serpentine barrens are a unique ecoregion found in parts of the United States in small but widely distributed areas of the Appalachian Mountains and the Coast Ranges of California, Oregon, and Washington.

Soils derived from serpentine are toxic to many plants, because of high levels of nickel, chromium, and cobalt; growth of many plants is also inhibited by low levels of potassium and phosphorus and a low ratio of calcium/magnesium. The flora is generally very distinctive, with specialized, slow-growing species.
Soil with serpentine is poor in calcium and other major plant nutrients, but rich in elements toxic to plants such as chromium and nickel. [20] Some species of plants, such as Clarkia franciscana and certain species of manzanita, are adapted to living on serpentinite outcrops.
Noxious weeds can be deadly for humans, animals and other plants in your garden. Here’s how to identify a plants before you get hurt. You may have poison in your garden.
For the most toxic houseplants, it’s smart to keep them out of reach of pets or out of your home completely, says Dr. Wismer. Ditto for toxic landscape plants; either fence them or don't plant them.
The timing of when you water plants impacts how effectively they can absorb water. But just as important as knowing when to water plants is knowing when not to water them.
The soil is often shallow and can be toxic due to high heavy metal concentrations such as nickel, cobalt and chromium. [4] As a result of the harsh conditions and unique edaphic properties presented by serpentine barrens these environments support stress-tolerant plant communities characterized by distinct and locally defined plant species.

The plants can suffer from root rot in cultivation if grown in stagnant, standing water and tend to thrive in areas where cold subsurface water slowly flows underground around their roots. It is not currently understood why the plants can withstand higher soil temperatures when found growing on serpentine soils.
