What would you plant in this gap?

[FoxandDuck]

In front of one hedge, I have a run of
lilac
some sort of prunus
GAP
redcurrant
viburnum
acuba
weigelia
cornus
buddleja
choisya

What shrub should I put in the gap? West facing but never in direct sun. I have ceonothus, forsythia, skimmia & berberis in prominent positions elsewhere so don’t particularly want to repeat them. I also have a hedge of photinia so am also ruling that out. It needs to be a bit of a thug as, whilst there is a gap, it will be competing with the established plants on either side of it and the hedge behind it.
Looking forward to hearing your suggestions!

I'd go for another weigelia, a different variety to the other one.

hydrangea? There are some very pretty lace cap ones

Rose?

Pittosporum tenufolium 'Tom Thumb'. Delicate, deep purple leaves with lime green new growth

Amelanchier

Sounds absolutely fabulous. Definitely missing a Pittosporum so many lovely ones to choose from

Hardy fuchsia. The one that grows tiny pink flowers is pretty vigorous.

I'd put another buddleia in a different colour, you did say it needs to be a thug!

You have a lot of deciduous shrubs in that list. Would another evergreen be an idea?
Maybe a yellow-variegated euonymus. Robust, can be clipped to shape. Its colour would echo the aucuba, and its leaf size/shape is a contrast to its neighbours.

Are you looking for an evergreen?

If evergreen, I’d suggest a pittisporum Elizabeth, which is variegated and has a pink tinge, it’s really pretty. Or escalonia Pink Elle, which has lots of lovely pink flowers in June. It’s really bushy, and very robust.

if deciduous, what about an Abelia? Mine flowers into October.

Some excellent suggestions! I started off with hydrangea in this area of the garden and they did nothing but are flourishing elsewhere. I have roses dotted around all over the place (and am very excited as I have so many buds on my Gertrude Jekyll this year as it has taken a while to get established). I can’t believe I overlooked escalonia & pittisporum! I’m going to plant an escalonia down there and then think I can squeeze a pittisporum in elsewhere.
Thank you!
