Propagation of Pelea Reflexa St. John Plant
Pelea reflexa St. John, also known as the Hawaiian Orange Pelea, is a rare and endangered plant species endemic to Hawaii. It has shiny, evergreen leaves and produces small, fragrant yellow flowers. The propagation methods for this plant differ depending on the type of propagation desired.
Seed Propagation
The easiest and most common way to propagate Pelea reflexa St. John is through seeds. The pods of the plant should be collected when they turn brown and start to split open. The collected seeds should then be soaked in water for 24 hours, after which they can be planted.
Since the seeds are very small, they need to be planted in a fine seed-raising mix and kept moist. It takes around 3-4 weeks for the seeds to germinate, and another 3-4 months for the plants to grow to a transplantable size. It is important to ensure that the seedlings do not dry out, as they are vulnerable to drying at this stage.
Cuttings Propagation
Another way to propagate Pelea reflexa St. John is through cuttings. Cuttings are taken from the stem of a mature plant. The cutting should be about 15cm long, with at least two nodes where the leaves emerge.
The cuttings should be dipped in a rooting hormone and planted in a well-drained potting mix. It is necessary to water the cuttings regularly, and to keep them out of direct sunlight until new growth appears. It usually takes around 2-3 months for the cuttings to root and start developing new growth.
Air Layering Propagation
Air layering is another propagation technique that can be successful for Pelea reflexa St. John. In this method, an incision is made in the bark of the plant and a rooting hormone is applied to the exposed portion of the branch. The incision is then wrapped with moist sphagnum moss and held in place with plastic wrap or a rubber band.
The moss is kept moist, and after around 2-3 months, roots will have formed at the cut. The rooted section can be cut off and planted in a potting mix, where it will continue to grow as a separate plant.
Overall, Pelea reflexa St. John can be propagated by seed, cuttings, or air layering. Each method has its own advantages, and the selected propagation method will depend on the availability of plant material and the intended use of the propagated plant.
