Been meaning to do this thread for a while!
I am thinking of things like - plants you've picked on a whim which have turned out to be fab, ones you thought wouldn't "work" which then surprised you, or ones which have given especially good "plant value".
The one that made me start thinking about this was a Knautia I got somewhere last year - totally unplanned & I didn't know much about them.
It didn't do much at all last year and I wondered if it was going to die... but this year it has grown beautifully bushy and been covered in flowers for MONTHS so I am very
with it.
I also love my Bellis as they seem to flower all through the Winter and most of the rest of the year too (though they are looking a bit stressed at the moment, hope they will be OK), and the heucheras are fab too as they always look great and don't need any attention.
What are yours?
