Coral pea 'Rosea' Hardenbergia comptoniana 'Rosea'

Water

The Australian sarsaparilla should be watered thoroughly, allowing the soil to become somewhat dry between waterings. In general, watering once a week is sufficient; however, in the warmer months, it may require more frequent watering, like twice a week. Water the plant with 1 to 2 gallons per session depending on the size of the plant and the dryness of the soil. It's important to avoid waterlogging as this can lead to root rot, so make sure the pot has good drainage.

Light

Australian sarsaparilla thrives in full sun to partial shade. The best spot for the plant would be in a location where it can receive at least 6 hours of sunlight per day. However, in extremely hot climates, some afternoon shade is beneficial to prevent leaf scorch.

Temperature

Australian sarsaparilla is a hardy plant that prefers temperate conditions. It can tolerate a temperature range from about 20°F in the winter to 100°F in the summer. The ideal temperatures for this plant are typically between 50°F and 85°F.

Pruning

Pruning Australian sarsaparilla is necessary to maintain its shape and encourage denser growth. It's best to prune the plant after it has finished flowering, usually in late summer or early autumn. Cut back any overgrown or dead stems to promote new growth. Pruning can be done annually or as needed when the plant appears to become too leggy.

Cleaning

As needed

Soil

The Native Wisteria thrives in well-draining, loamy or sandy soil that is rich in organic matter. A suitable soil mix for this plant can include two parts loam, one part sand or perlite, and one part compost to ensure good aeration and drainage. The ideal soil pH for Hardenbergia comptoniana 'Rosea' is slightly acidic to neutral, ranging from 6.0 to 7.0.

Repotting

Native Wisteria does not require frequent repotting and can be done every two to three years, or when the plant has outgrown its current container. It's best to repot in the spring as the plant enters its active growth phase.

Humidity & Misting

Native Wisteria prefers moderate humidity levels, similar to what it experiences in its native Australian habitat. Around 40-50% relative humidity is adequate for healthy growth, but the plant is quite adaptable and can tolerate lower humidity environments.

Suitable locations

• Indoor

  Use well-draining soil and bright indirect light.

• Outdoor

  Plant in well-draining soil, full sun to partial shade.

• Hardiness zone

  9-11 USDA

Life cycle

Native Sarsaparilla 'Rosea', or Hardenbergia comptoniana 'Rosea', begins its life cycle as a seed, which germinates in optimal light and soil conditions, developing a root system and cotyledons. It then enters a vegetative stage, wherein the plant develops a robust climbing structure with long, twining stems and trifoliate leaves. Following the vegetative stage, it reaches maturity and flowering occurs, typically in winter to early spring; the plant produces pink to rose-colored pea-like flowers. After pollination, the flowers develop into seed pods that contain the seeds for the next generation. Once mature, these pods dry and release their seeds into the surrounding environment, completing the life cycle. The plant's longevity allows it to repeat the flowering and seeding process for several years, while also potentially spreading vegetatively through rooting at stem nodes.

  Spring to Summer

• The Australian native plant known commonly as Native Wisteria, specifically the Hardenbergia comptoniana 'Rosea' variety, can be propagated through several methods, but the most popular is by semi-hardwood cuttings. This technique usually takes place in late summer or early fall when the plant's growth has started to harden but is not yet fully mature. To execute this method, a gardener would cut a 4 to 6-inch (about 10 to 15 centimeters) piece of stem from the current season's growth, ensuring the cutting includes a few leaf nodes. The lower leaves should be stripped, and the base dipped in rooting hormone to encourage root development. The cutting is then planted in a well-draining potting mix, kept moist and in a warm location with indirect sunlight until roots have formed, which can take several weeks to a few months. Once the cuttings have rooted well, they can be transplanted into individual pots or into the garden.
