Here here, BB2, Dave, Duncan and Goodday. I've found almost any gardener will let you take a few discreet cuttings of a plant you see, if you ask politely. You mihkt even get invited in to the back garden to see if there's anything else that takes your fancy!
An old gentlemen I once knew dragged me in and proceeded to dig up half his garden for divisions for me. I still take cuttings every yr from a standard fuchsia he bought for my Birthday. It was my first ever standard, and now I'm getting a bit obsessed with them! Just asking the name of his begonias led to a great friendship, and all of my orchids came from him. I still keep in touch tho I have moved to Scotland. He is 93 and frail now, but still loves to know how my garden is doing. Gardeners love to share, in my experience, which is why this forum is so popular.
Incidentally, he is 50yrs and 2 days older than me, so that is one birthday I can never forget! I hope he makes his telegram.
