Sexual Reproduction
Wisteria floribunda ‘Alba’ produces seeds that can be collected in the fall after the flowers have faded. After collecting the seeds, clean and dry them for a few days before planting them in soil that is moist but well-drained.
Cover the seeds with soil and ensure that the soil remains moist. Germination takes place in approximately two to three weeks, and seedlings should be transplanted once they have two to three leaves.
Asexual Reproduction
Propagating Wisteria floribunda ‘Alba’ through vegetative methods offers an easier and faster way to produce new plants with the same genetic makeup as parent plants. Below are some asexual propagation methods:
Cuttings – This method involves taking cuttings from a mature plant, dipping the cut end in rooting hormone, and planting the cutting in a potting mix.
Keep the soil moist, and with time, roots will form, signifying the success of the propagation. This method works well for both hardwood and softwood cuttings.
Layering – This technique involves bending one of the plant’s branches to reach the ground and then burying the bent portion in soil. By doing this, part of the branch lies in the soil, and roots develop from the buried part.
The layer can then be severed from the parent plant and transplanted. Grafting – This technique involves joining a shoot of the desired cultivar, known as the scion, to the rootstock of a closely related Wisteria species.
However, grafting requires some experience to achieve success.
