Geum is the genus which containes Geum rivulare (water avens) and Geum urbanum (wood avens) - but it also contains about 48 other species. I'm not sure which the wild type is for cultivars such as Totally Tangerine. There are some which are much closer to Geum rivulare and definitely prefer wetter soils, but I think most of the more familiar cultivars do OK in most soil types.
Hi @GardenerSuze I think so - not 100% sure but they are similar in leaf and flower (apart from colour). I am intrigued now, going to have to look this up...
@GardenerSuze so Lady Stratheden, Mrs Bradshaw, Blazing Sunset and Totally Tangerine are all cultivars of wild type Geum chiloense. Totally Tangerine is actually a hybrid of Lady Stratheden and the wild Geum rivulare (water avens), which I didn't realise - but I think that it still needs moist but well drained soil as a rule.
@BlueBirder Thank you for all your research not sure I would have known where to start. I did think that TT was a more recent introduction but knew nothing about it's origins. I think it is one of the best Geums to grow because it flowers for such a long time.
I have worked as a Gardener for 24 years. My latest garden is a new build garden on heavy clay.
@punkdoc as a pedant myself, I don't mind your correction! Thank you - one of the names which has got stuck in my head incorrectly. I think because 'rivulare' sounds like 'rivulet' which is to do with water...
