Gardeners' Notes:

I bought two plants last May. Planted them and they filled up a huge area within a few months (20 x 20 foot area) I had to cut it back twice. They are blooming now, get very little water, and grow like weeds. they do get damaged from frost. They do need to be covered.
When I watered them over summer I watered two times with long slow soak each time.
They can be considered invasive, and they have a mind of their own as far as where they want to grow.
\They do have some leaf litter under the new growth.
Approximate life span is 3 years, pruning will lengthen their life.
this info aside from personal experience came from Australian Native Plant Society.

The flowers on this plant look like bees as they are black and yellow. A nice hardy vine, but it does have a mind of it's own, wandering off the trellis an up a neighboring bush.

This West Australian climbing pea, is very unusual in having black flowers (well black and yellow). The large pea flowers are borne over a long period through the spring and summer, and are attractive to nectar-feeding birds. Its drawback is its vigour. Our plant has spread along more than 10 metres of fence, forming a thick hedge from a single plant, and it tends to climb vigorously over any other neighbouring shrubs.
