Love this plant! I have gardened for many years and did not know about it until I visited my homeland, South Africa, a couple of years ago and just had to have it. I was so excited when I found it at our local nursery last summer. I have it growing on a very difficult to propagate bank and it does so well. It is a fast grower and once established does not need much water (which is great with our water situation in California). We had heavy frost this past winter and I was unable to protect it ahead of time and really thought I had lost it all. I decided to leave what was left of the plants and tend to them last on my rounds of the yard this spring, and amazingly, they have come back beautifully which made me think they are more of a perennial than an annual. They really looked dry and dead, but came back . I am currently pulling other plants in order to plant more of the Evolvulus for an even more showy display. Highly recommended!
