I saw some plants at Bunnings the other day for $1 each, in reasonably big pots. I didn't recognise the leaves and they had no flowers but when the shop lady told me that they were Gauras I bought all four.
I was pleased when they turned out to be white, and they look lovely in the garden. I have 2 gauras already but they tend to sprawl. These ones are more upright which suits me better
