Propagation Methods
Viola purpurea Kellogg ssp. atriplicifolia (Greene) M.S. Baker & J.C. Clausen ex M.E. Peck can be propagated through seeds or by vegetative methods.
Seed Propagation
The easiest way to propagate Viola purpurea Kellogg ssp. atriplicifolia (Greene) M.S. Baker & J.C. Clausen ex M.E. Peck is through seed propagation. The seeds need to be stratified, which means they need to be put in moist, cold conditions for about a month before sowing in the spring. Sow the seeds in a potting soil mix and cover with a very thin layer of soil. Water and keep the soil moist until the seeds germinate, which usually happens in about 2-3 weeks. Once the seedlings have a few true leaves, they can be transplanted into individual containers or directly into the garden, if weather conditions permit.
Vegetative Propagation
Viola purpurea Kellogg ssp. atriplicifolia (Greene) M.S. Baker & J.C. Clausen ex M.E. Peck can also be propagated through vegetative methods, which include division or taking stem cuttings.
To divide the plant, dig up the whole plant and gently separate the root ball into smaller clumps. Each clump should have at least one healthy shoot and some roots. Replant the clumps in potting soil or directly into the garden.
To take stem cuttings, select a healthy stem with a few leaves and a node. Cut the stem just below a node and remove all but the top few leaves. Dip the cut end in rooting hormone and plant the cutting in moist potting soil mix. Keep the soil moist and in a warm, bright location. The cutting should root in about 2-3 weeks and can be transplanted into its own container or directly into the garden.
