Kent, United Kingdom

I want to purchase an agapanthus called “Angela” and I wonder if anyone can suggest a mail order site or someone that I could purchase one from. I have scanned the net and drawn a blank. The only place I found was Avondale Nurseries but they don’t do mail order I pleaded with them but they would not relent and said there was only two of them and they had not got time to send one.
