Origin and Common Names
Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone is a plant species that belongs to the citrus family, Rutaceae. It is commonly known as the Maunaloa clusia or the Pelea tree, a native Hawaiian plant that grows in dry to mesic forests of Hawaii. It can be found in the islands of Maui, Molokai, and Oahu.Uses
The Pelea tree has been traditionally used by the native Hawaiians for a variety of purposes. Its wood was used to make kapa beaters, adzes, and digging sticks. Its bark was also used for medicinal purposes, including treating coughs, skin diseases, and gastrointestinal problems. The leaves of the Pelea tree were consumed as a source of vitamin C. The Pelea tree has also been used for reforestation purposes and as an ornamental plant. It is drought-resistant and can survive in poor soil conditions.General Appearance
Pelea peduncularis Levl. var. pauciflora is a small to medium-sized tree that grows up to 8 meters in height. Its trunk is gray-brown and has fissures, while its bark is dark brown and exfoliating. The tree's leaves are oblong or elliptic, and its flowers are small and white. The fruit of the tree is a drupe that is greenish-yellow when immature and turns orange-yellow as it ripens. This plant has a unique characteristic that sets it apart from other trees in Hawaii. Unlike other tree species, the Pelea tree is dioecious, meaning it has separate male and female individuals. The male flowers have five sepals and no petals, while female flowers have five petals. In conclusion, Pelea peduncularis Levl. var. pauciflora is an important plant species in Hawaiian culture, with multiple uses and a distinctive appearance that makes it a valuable addition to the ecosystem.Light Requirements
Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone thrives in full sun to partial shade. It requires at least 4-6 hours of direct sunlight for healthy growth and development. When grown indoors, it is advisable to place the plant near a south-facing window where it can receive ample sunlight.
Temperature Requirements
The plant prefers a warm and humid climate and can survive in temperatures between 60-80°F (15-27°C). It is important to ensure that the temperature does not fall below 60°F (15°C) as it may cause damage to the plant. In cooler climates, it is advisable to grow the plant indoors or in a greenhouse where the temperature can be regulated to suit its growth requirements.
Soil Requirements
The ideal soil for Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone is loamy, well-draining, and nutrient-rich. A pH range of 5.5-7.5 is optimal for the plant's growth and development. It is important to avoid waterlogging the soil as this may lead to root rot. Adding organic matter such as compost or aged manure to the soil can improve its fertility and texture.
Cultivation Methods
Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone thrives in well-draining soil with a pH range of 6.5 to 7.5. If you're planting the Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone in containers, choose a pot with a drainage hole to avoid waterlogged soil. In areas with hot climates, it's best to plant the Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone in a location with partial shade to avoid plant stress.
Watering Needs
The Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone requires regular watering for the first few months after planting. Once the plant is established, reduce the watering to once a week or when the soil feels dry to the touch. In hot or dry climates, increase the frequency of watering to twice or thrice a week to keep the soil moist but not waterlogged.
Fertilization
Fertilize the Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone every three to four months with a slow-release, balanced fertilizer. Before applying the fertilizer, water the plant to help the fertilizer penetrate the soil. Avoid applying too much fertilizer, as it can result in excessive foliage growth with limited flowering.
Pruning
The Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone benefits from annual pruning to maintain its shape and height. Prune the plant during late winter or early spring before new growth emerges. Use clean and sharp pruning tools to avoid tearing or damaging the plant. Remove dead or damaged branches, along with any branches that cross or rub against each other.
Propagation of Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone
Pelea peduncularis Levl. var. pauciflora (St. John) B.C. Stone, commonly known as Hawaiian Pelea, is a flowering plant that is endemic to Hawaii. It is a shrub that can grow up to 6 meters tall and is usually found in dry or mesic forests. The plant can be propagated through a few methods which are described below.
Seed Propagation
The most common method of propagating Pelea peduncularis is through seed. The seeds should be collected from mature fruits that have turned brown and are beginning to split open. The seeds should be cleaned and soaked in water for 24 hours before planting. The seeds can be directly sown into a pot or garden bed. They should be covered slightly with soil and kept moist until germination, which usually occurs within 2-4 weeks. Young seedlings should be transplanted once they have developed a few true leaves.
Cuttings
Pelea peduncularis can also be propagated through stem cuttings. Softwood cuttings, which are taken from the current season's growth and are still green, are the easiest to root. The cuttings should be approximately 10-15 cm long and have at least 2-3 nodes. The leaves on the lower half of the cutting should be removed, and the stem should be dipped in rooting hormone. The cutting should be planted in a pot with well-draining soil and kept moist. It can take up to 4-6 weeks for roots to develop. Once the roots have developed, the cutting can be transplanted to a larger pot or garden bed.
Air Layering
Air layering is another method of propagating Pelea peduncularis. It involves stripping a section of bark off of a stem, applying rooting hormone to the exposed area, and then wrapping the area with damp sphagnum moss and plastic wrap. Roots will form within the moss, and the new plant can be cut off from the parent plant and transplanted once they have developed.
Propagation of Pelea peduncularis can be quite easy and straightforward with the right techniques. Seed propagation, cuttings, and air layering are all methods that can be used to propagate this Hawaiian native plant.
