We have a small raised bed in front garden, currently planted with a few small flowers and some spikey plants like this.
They are getting big and bit odd looking, so would like to replace them. It's a north-east facing space, right by a very main road so we do need something that gives a bit of privacy but not too dense as it would then make some of our rooms quite dark. Doesn't need to be very tall, maybe two or three feet.
Does need to be easy, as I am a very novice gardener. We're in London so soil is clay-ey, though in this bed it's not too bad drainage wise because of the raise and I think that it has a lot of rubble underneath
Was thinking lavender at one point, but not sure if it's sunny enough. But something like that, a shrub hedge rather than tree hedge, would be great.
Also love hollyhocks and geums but not sure how they would work in the urban setting.
Any advice much appreciated!
