Hi Charles - this sounds like an exam question, check you course file or do a google search!

I last wrote an exam 35 years ago. Thanks for the compliment though. I like my Canna for the vivid colours it brings, the ease of planting and maintaining, and I am looking for similar for a new garden. No course notes available and google does a lot of things but this is an enquiry too far. Any ideas?

beauty is sumthin you only can see, but for size try iris

How about lovely Dahlias for later beauty...:>)
