Here is a real beginners question!
I have a sunny border I'm planning, it's my biggest bed to date and is also being planned from scratch as it's currently bare. It's about 8m by 2m wide and I'm envisioning a country garden style with hollyhocks, lupins etc... Here is my question though, how do you decide how many of each plant you want? Now I've written it down it sounds like a really silly question! It's just that I've read that you should plant in threes but does that mean 3 groups or 3 plants? Is this also true for planting in 'drifts'?
