A bought some staghorn sumac 30 years ago in Galena IL from a local landscaper. A big mistake! I asked him for a variety that wouldn’t get too tall and produce a colorful patch for privacy. Over the early years they really took off! But they started to become trees rather than shrubs to say the least! They took over getting taller and taller. I had to start cutting them down as they were starting to grow on my neighbors property. It took several years to remove them. What a relief!!! I haven’t seen anymore sprouts in years. Guess what… about a dozen shoots popped up this summer. What’s the best way to eradicate them?

Good overview..
I understand national collection holder Melanie Domb said that aconitum napellus anglium group is the earliest to flower.
I cannot find any uk supplier, could she or anyone suggest?
Also I gather she is wanting to identify an April flowering one found in her garden. Interesting as I have a similar, pale blue, also obtained from an old garden, and I've no idea which it is! Sorry can't help!

i live in the east bay area of san francisco, CA. i have a bizarre microclimate that allows me to grow many plants that would otherwise not survive. i'm desperately looking for a source anywhere in the US or canada that would have blackthorns (prunus spinosa) for sale. i wish to grow a hedgerow with them. is it possible that you may know of a reliable grower/seller of blackthorns? thank you for your consideration. mrs m holmquist
