Prohibited Plants

Today we all know that we should protect our environment! Some states ban the sale and/or ownership of invasive plants and label them as "Prohibited" or "Noxious" plants.
An invasive plant has the ability to thrive and spread aggressively outside its natural range. Non-native invasive species are organisms that have been introduced by humans either purposely or by accident and that have become serious enviromental pests. A naturally aggressive plant may be especially invasive when it is introduced to a new habitat. An invasive species that colonizes a new area may gain an ecological edge since the insects, diseases, and foraging animals that naturally keep its growth in check in its native range are not present in its new habitat. 

Invasive alien plants threaten native species by competing for critical and often limited resources like sunlight, water, nutrients, soil and space. Invasive plant species displace and alter native plant communities, change soil chemistry, cause genetic changes in native plant relatives through hybridization and some serve as agents for the transmission of harmful plant pathogens.

Please, do the environment a favor and be responsible! Do not release purchased aquatic plants into natural bodies of water, streams or storm drains, as they are intended for use in your decorative and/or enclosed pond, only.

If you must get rid of excess aquatic plants....bury them, give them away or kill the plants by drying them out in the hot sun or compost them in your compost pile.

The following list is a list of some common plants that are prohibited for sale in the states that follow them, and cannot be sold in those states. Before making a plant purchase, please look over this list to see if the plants that you have selected are on it.
