Perhaps you’re wondering about the name Rulingia Lookout. It has a special story behind it.
Rulingia refers to a plant genus. It is part of the Malvaceae family. This family includes everything from small shrubs to large trees like the Flame Tree.
Rulingia hermanniifolia is one notable species. It’s a low-growing sub-shrub. This plant forms dense mounds, about 20 cm high and 1 m wide. Its deep green wrinkled leaves are attractive. It is suited for rock gardens. It flows gracefully over the rocks.
In spring Rulingia hermanniifolia has pink tinged buds. Small star-like flowers appear in cymes. The flowers open white. Then, they fade to pink with a red centre. This creates a beautiful contrast. New flowers replace the old ones. The fruit is a deep red capsule. It is about 4 mm in diameter. It provides colour from late November.
Propagation is usually by seed or cuttings. Half-hardened wood taken in December or January works best. Commercial hormone powders can help cuttings strike faster.
Rulingia hermanniifolia is frost hardy. It enjoys full sun. Heavy shade can make its growth sparser. It grows naturally in Sydney sandstone regions. Its habitat overlaps with the Rock Wallaby. Rock Wallabies often damage its foliage by cropping it regularly.
The genus Rulingia is named after J. Ph. Ruling. He was a botanist from Gottingen.
