Tree Roses

Common name:Tree Roses
Botanical name:Rosa Tree varieties

Tree roses are actually shrubs that have been grafted or grown in a way that looks like a tree, ie with a trunk. Tree roses can be floribundas, hybrid teas, or grandifloras. They are typically used as specimen plants. Make sure the plant is tied to a stake in case of strong winds.

Australian Willow, Wilga

Common name:Australian Willow, Wilga
Botanical name:Geijera parviflora

This evergreen tree reaches a height of 25', with 3"-6" long, medium length, green colored leaves that are narrow. Its main branches sweep up and out, while the smaller branches tend to hang down.

Quartz Creek Rush

Common name:Quartz Creek Rush
Botanical name:Juncus effusus pac. 'Quartz Creek'

This selection of Juncus is widely used in landscapes due to its carefree nature, rigid upright structure and bright green color. This Juncus initially grows very rapidily and then slows to eventually to 36" wide and then clumps. It will reach a height of 24"-36". It reguires fairly regular water in the warmer months to perform well.
