Help me plan my new planter

[llamadrama16]

I have a big (for me!) new planter out the front of my house. I'm a very new gardener so if anyone wants to help me plan it I'd be so grateful! It's 370cms in length, 75cms wide, and 25cms deep (so can't take anything too deep rooting). There's also another 100cmx75cm bed at the back as it's in an L shape.

I am planning some Mexican fleabane in the front and some trailing rosemary as I want some things which are going to tumble over the edge. I love broom so make some other that. Otherwise I'm open to suggestions!

Bulbs!

you need to think about how it will look all year round- fleabane is superb and long flowering (easy to grow from seed too) but it will die right back in winter. Rosemary is fine - just need to use it so it doesn’t get too woody. So think about evergreen bushes or ornamental grasses backdrop then use your flowers to switch it up in each season. As previous poster said bulbs are great as they will basically grow anywhere- so you can have snowdrops followed by crocus, mini daffs/narcissus (big daffs and narcissus get messy when they die back) to tulips, then alliums. Not sure about if your broom would work as your planter seems shallow and it prefers acid soil I think-maybe someone more familiar with it can help. There are loads of evergreen hebes of all sizes and colours though that would be ok or you could include some clipped topiary (box ball type stuff). If it’s a shady spot you can use ferns.
