Aubrieta

Bought some aubrietas today to experiment with, could I plant these in the wall border and then would they grow over the wall or do I need to raise the soil more for this to happen?

 

That seems a little low for them to grow up and over the wall. They really need to be level with the wall to trail over.
These are my 3 yr old plants grown from seed.View attachment 45889
And these are grown from seed last July.

 

This is what I call the "Wall Weed".................


It is fully hardy in the wall and clearly has very minimal nutritional requirements. Get some large stones to mound up in a couple of spots next to the wall and plant them into those.

 

Good idea, will go stone hunting

 

Love these, mine responded well to a good chop back after flowering last year and I managed to get a couple more from cuttings too.

 

Yeah, I agree they grow anywhere, if you look closely at the bottom right of my pic you'll see some there that have seeded themselves into the tarmac on the drive. Don't wanna get rid of them yet incase they throw up something a bit unusual.

 

I have planted some aubrietia in my border because I love them how long do they take to spread? And is it correct to cut them back by half when they finish flowering?

 

If you look at my top pic, the blue ones are three yrs old.
I always cut them back by at least half to a couple of good sideshoots otherwise they tend to grow too leggy and you end up with a plant 3 ft away from where you planted it as they root as they go and the original crown dies.

 

PS.... All the growth overhanging the wall will be cut off with shears level with the top of the wall to grow back during the summer.
