Pittosporum eugenioides
Pittosporum eugenioides, commonly known as Karo, is an evergreen tree or large shrub native to New Zealand. It's known for its glossy, leathery leaves, which are obovate to elliptic in shape and have a distinctive aroma when crushed. The plant produces fragrant, creamy-white flowers in spring, followed by sticky, orange-brown seed capsules. It can grow to a considerable size, reaching heights of up to 15 meters (49 feet) in ideal conditions. It's a popular ornamental plant due to its attractive foliage and relatively easy cultivation.

Cultivars

Leptospermum scoparium
Both species thrive in similar conditions – full sun to partial shade and well-drained soil. They complement each other aesthetically, with the contrasting textures and colors of their foliage.
Eucalyptus globulus
Tasmanian blue gum
Eucalyptus globulus

Eucalyptus globulus is a fast-growing tree with a large root system that will compete for water and nutrients, potentially stunting the growth of Pittosporum eugenioides.

Aphids

Aphids are small, soft-bodied insects that suck sap from the leaves and stems, causing leaf curling, yellowing, and stunted growth. They can also transmit plant viruses.

Scale insects

Scale insects are small, immobile insects that feed on plant sap, resulting in yellowing and dropping of leaves. They excrete honeydew, which can lead to sooty mold growth.

Steps:

    • Take semi-hardwood cuttings in late spring or early summer.
    • Dip cuttings in rooting hormone.
    • Plant cuttings in a well-draining potting mix.
    • Keep cuttings moist but not waterlogged.
    • Provide bright, indirect light.
