Propagation of Gaura parviflora Dougl. ex Lehm.
Gaura parviflora Dougl. ex Lehm. can be propagated through several methods such as seeds, basal cuttings, and division of root clumps.
Seed Propagation

Basal Cutting Propagation
Gaura parviflora can also be propagated through basal cuttings. Collect cuttings from young, vigorous growth in early spring just as the buds break. Cut a 10 to 15cm length of stem, remove all leaves except for the top two, and plant in a well-draining potting mix. The cutting should be kept moist and in a shaded area until it roots. After three months, the cuttings can be transplanted to the garden.
Division of Root Clumps Propagation
Gaura parviflora can also be propagated through division of the root clumps. This method is best done during early spring or fall when the plant is not actively producing flowers. Use a sharp spade to divide the clump, ensuring that each section has enough roots and stems. Replant each section in well-drained soil and keep the soil moist. The transplanted plants should be watered regularly until they are established, usually in six to eight weeks.
