If you type 'Garden Design Software' it comes up with loads some aimed at the professionals and others at amateurs. There is a free download list from Gardeners World shown. Anyway it might be worth you looking.
So when do you go Dove because that is exactly what is needed
I have Rudbeckias on clay soil and they love it.
Trachelospernum jasminoides might be OK in a pot. Has the benefit of a beautiful scent. You will need to be very diligent in watering for any climber
The plants seem to be loving this weather.
It could be a Hibiscus but not sure which variety
They will be caterpillar eggs. Squash immediately or you won't have any cabbages to harvest
Thanks Dove, that's very useful. I'll give it a try.
Have you tried the company website? They may have a FAQ page that might help.
Thank you Dove
