Hibiscus brackenridgei
Hibiscus brackenridgei, also known as the Hawaii hibiscus, is a species of flowering plant in the mallow family, Malvaceae. It is endemic to Hawaii and is considered the state flower. It's a shrub or small tree with large, showy flowers that vary in color from white to deep red and can have multiple colors on the same flower. The flowers are typically large, reaching diameters of 4-6 inches (10-15cm). They are known for their distinctive, often deeply lobed petals. The plant can grow quite tall, up to 10-15ft (3-4.5m) in optimal conditions.

Carnations are relatively low-maintenance, like Hibiscus brackenridgei, and won't compete aggressively for resources, making them suitable companions. They add contrasting textures and colors to the garden.

Leucaena leucocephala is a fast-growing, aggressive tree that can quickly outcompete Hibiscus brackenridgei for sunlight, water, and nutrients. Its dense canopy would shade the hibiscus and inhibit its growth.

Aphids

Small, soft-bodied insects that suck sap from the leaves and buds, causing stunted growth, yellowing leaves, and honeydew secretion. They can also transmit viruses.

Spider mites

Tiny arachnids that also feed on plant sap. Infestations result in stippling and webbing on the leaves, leading to leaf discoloration and drop.

Steps:

    • Take 4-6 inch cuttings from semi-hardwood stems in spring or summer.
    • Remove lower leaves to prevent rot.
    • Dip the cut ends in rooting hormone.
    • Plant cuttings in a well-draining potting mix.
    • Keep the soil moist but not soggy.
    • Provide bright, indirect light.
    • Transplant once roots have developed.
