It is a a vigorous climbing plant whose branches twist around the stems of other plants. The flowers. which appear in winter and spring are usually mauve to purple in colour but pink and white forms are known and are a typical 'pea' shape.
It has been in cultivation for many years and is widely grown both in Australia and overseas. It has proven to be very hardy in a wide range of climates and most reasonably drained soils. It will grow in sunny or lightly shaded locations. Bear in mind it is very vigorous and is best grown on a strong support such as a fence or trellis rather then allow it to grow over smaller shrubs. Propagation is easy from seed following pre-treatment to break the physical dormancy provided by the impervious seed coat.
Hypocalymma robustum (Swan River myrtle) is a species of open shrub endemic to open forests and woodlands of the southwest region of Western Australia. It grows in the jarrah forests of our Darling Ranges near Perth.
It usually grows to between 0.4 and 1 metre in height and has pale to dark pink flowers which are produced between June and November (early winter to late spring) in its native range. The scented flowers cluster around the stem. It is a desirable garden plant but it needs a climate where the summers are dry as well as good drainage. It will grow in a sunny or partially shaded position and has moderate frost tolerance.
I love them all but the last one always catches my eye as yellow (as some of you may know) is my favourite colour.
