D.arcuata.JPG (47852 bytes)Derwentia arcuata: is a member of the Scrophulariaceae family in company with the exotic Snapdragons and Foxgloves. The Derwentias have had chequered horticultural career. Firstly all species were included in the Veronica and then Parahebe before becoming Derwentia.

Derwentia arcuata is a small, multi-stemmed shrub. The leaves are narrow to narrow-ovate, V-shaped in cross section, curved downwards, dark green in colour and opposite.

Profuse lilac flowers are carried in terminal racemes and appear in spring and summer. There is between 20 to 85 flowers in each raceme. Each stem only carries flowers for one season. As flowers fade cut off each stem. This will encourage new stems and more flowers next season.

The species was only named in 1992 and is found in northern New South Wales.

Derwentia arcuata is a colourful plant and could be cultivated in a number of situations. Perennial native borders, cottage gardens and rockeries would all benefit from the inclusion of this attractive plant.

Propagation is from cuttings. These strike readily and rapidly.

We first found this Derwentia growing in clumps on a rocky outcrop on the campus of the University of New England. From a distance the plants appeared to be Wahlenbergias (Native Bluebells). Cuttings were taken and now we are planting Derwentia arcuata to many of our gardens. We are cultivating two other species: Derwentia arenaria and Derwentia perfoliata.  

The species name means arching or curved and refers to the shape of the leaves.
