In fact, this is the light lilac flower variety as there is another darker purple flower variety that we have.
It has a more low sprawling habit compared to the Buddleia asiatica in the background. So far, I have seen various butterflies e.g. Common Birdwing, Common Rose, feeding on the flowers for their nectar. In overseas, it is recorded as a butterfly nectar plant.
This is also one plant that I used in the Garden of Seasons as it gives a more exotic feel to the garden since it is not planted anywhere else in Singapore (at least that is what I think).
Well, so far our propagation efforts did pay off with this batch of sizeable plants but a problem we encountered is the plants start to wilt and die one by one. It could be this plant is susceptible to a fungal wilt disease. Until we are able to propagate a more resistant variety, it may be hard for us to introduce it to our parks and streetscape.
