Many people think that all seeds are sold for landscape or garden use. We actually sell seeds to all kinds of end users. Some are sold for medical research or to extract chemicals and drugs used to advance human, animal, or plant health. We also sell some seed to universities and chemical companies who are trying to find ways to control an invasive plant's spread. When we sell seed of a known weed or invasive plant we abide by all the regulations of each region. We post invasive warnings on applicable seed lots, but it is always a good idea to know and stay up to date with your states regulations/recommendations.
We believe that it is proper to sell these species because there is a critical need for them. We do not advocate using these seeds for landscaping or gardening outside of their natural range!
