Clematis is a deciduous vine that produces flowers in mid-spring to mid-summer. It grows best with support and partial shade for its roots. Nursery crops are perennial plants grown for landscaping, including trees, shrubs, and ground covers. Nurseries can be field grown or container grown. Field grown nurseries plant directly in the ground while container nurseries grow plants in pots that require daily irrigation but allow year-round harvesting. New growing methods include fabric grow bags and pot-in-pot systems.
