Propagation Methods for Asarina Stricta (Hook. & Arn.) Pennell
Asarina stricta (Hook. & Arn.) Pennell, commonly known as the Twining Snapdragon, is a beautiful plant that originates from Mexico. It is an evergreen perennial or annual herbaceous plant that produces stunning, deep blue-violet flowers that bloom from late spring to early fall.
Propagation by Seeds
The most common method of propagating Asarina stricta is by using seeds. The plant produces small, brown seeds that should be sown in the early spring. The seeds should be placed on top of the soil and lightly pressed into the surface. After planting, water the soil gently and provide shade for the seeds.
It is important to maintain a consistent temperature of around 65°F (18°C) for the seeds to germinate. The seeds usually germinate in 2-3 weeks, and once the seedlings are big enough to handle, they should be transplanted to their permanent location about 6-8 weeks after planting.
Propagation by Cuttings
Another method of propagating Asarina stricta is through cuttings. This method is useful for those who want to produce plants that are identical to the parent plant. Take cuttings from healthy and mature plants in the summer or early autumn. The cuttings should be around 4 inches long and should be taken from near the base of the stem. Remove the leaves from the lower half of the cutting and dip the end in rooting hormone powder.
Place the cuttings in a container filled with a well-draining soil mix and keep the soil moist but not waterlogged. Provide shade for the cuttings and maintain a temperature of around 65°F (18°C) until the cuttings have rooted. After about 4-6 weeks, the cuttings should have rooted and can be transplanted to their permanent location.
Propagation by Division
Asarina stricta can also be propagated through division. This method is suitable for mature plants that have multiple stems and a well-established root system. In the early spring, dig up the plant carefully and separate the roots into small sections, each containing a portion of the stem and some roots.
Replant each division in well-draining soil in a location where it can receive partial shade and water regularly until the plant has established itself.
By following these propagation methods, you can produce healthy and beautiful Asarina stricta plants for your garden or for sharing with others.
