I've only been gardening in the UK for a few months and am still learning the names of plants. However, the following continue to be on my unknown list and I would really appreciate finding out what they are.
Top picture is some form of Tradescantia I think.
Middle one is a lily
Bottom one is Hypericon, (also known as Rose of Sharon) You can cut this back like a hedge after flowering if you wish, some people have problems with lots of seedlings coming from this plant, though I personally don't.
Other people on this site will tell you the varieties I'm sure.
I've been searching on Google images and I'm glad that one of the three is native to Britain (Hypericum androsaemum). I think I've found the species name for the Tradescantia too (T. virginiana). I had the feeling that the Hypericum might want to self-propagate rather easily but I didn't want to get rid of it — it's good to know that I can cut it back quite hard.Thank you for the welcome, and for the names.
Hypericum spreads with seed and root. It can be invasive if not kept in check, but it's not difficult to do so. If you don't want the seeds to spread, just take off the tops with shears, you do lose the reddish heads as a result which are nice as an autumn colour.I find digging the best solution.
In spring give it a serious haircut which helps keep it in check.
There are pretty & tame hypericums, but the common 'rose of sharon' is not one of them, just be warned about just how rampant this plant can be. We moved into our present house 17 years ago, where it was in borders front and back of the house. i have cut it below ground level every time I see it, pulled up miles (with very little exaggeration) of roots, and it is still coming back.
That hypericum seeds about well but isn't invasive by root, I woouldn't worry about it
Sorry about the lily
Thanks for the warnings about the Hypericum. The red autumn colour is very attractive, as are the black seedheads, but I will certainly keep an eye out for rampant seedlings. I have a couple of clumps which haven't spread as yet, but I did (experimentally) dig around the edge of one in the summer and decided it had very strong roots. Hopefully, H. androsaemum is one of the "tamer" varieties.
Artjak, don't apologise! Thanks to Mark, I now know that the Peruvian Lily (Alstroemeria) is of the lily family, so you were spot on!
