It's interesting that you say that re montbretia/crocosmia @Silver surfer. When I joined the forum - which is when I moved into this house - I commented on the amount of crocosmia there was around the site. A well known, very knowledgeable member [no longer on the forum] gave me real grief about it. He said it was montbretia, as it was only the cultivated ones which were called crocosmia
No expert ...it is not a native plant in UK. I found this. Originally from South Africa. Quote below........ "Scientific name: Crocosmia x crocosmifolia Hybrid of: Crocosmia aurea x Crocosmia pottsii
Montbretia is listed under Schedule 9 to the Wildlife and Countryside Act 1981
with respect to England and Wales. As such, it is an offence to plant or otherwise
allow this species to grow in the wild. "
I’ve separated them out & popped them in plastic pots with a little compost & grit for now to see how they do I’m hoping that they’re now thinned out I’ll get more flowers this summer!
