In a muddle about Euphorbia Mellifera
I bought this plant as a centrepiece for a new ‘oranges and lemons’ shrub border next to my new patio, pictured below, attracted by its honey scent. Now I wonder if it’s going to get too big for the 160cm diameter space I have. I initially read (think it was Beth Chatto) that it’s spread was 150cm but having checked, other sites say 250cm, which would be far too large and overwhelm the other plants. If it does get out of control, is it easy enough to keep in check with pruning or would I be planting a monster?
The other plants are roses Charles Darwin, to the left, Golden Celebration and a trio of Lady Emma Hamilton to the right and a Cytisus Lena in front.
The alternative I have to hand is a Pittosporum Tenuifolium Atropurpurea - originally bought for another border, but would perhaps set off the yellows and oranges of this one...
Hmm, which one to go for? Or neither?!

I am happy for it to grow tall, it’s at the back, just worried about its spread, but if you think I can keep that under control...
Ooh, that’s a weird looking one FD, tho having already got too many plants for spaces available, I think I need to decide between the Mellifera and the Pittosporum Tenuifolium Atropurpureum.
Anyway, time to go and do some actual gardening!
Freddies dad I've never seen a tom thumb like that before, I've only ever seen them grown as dense mounds!
I am still swithering about whether the E. mellifera will get too wide for that space, but maybe I’ll just plant it and see how it goes - I suppose I can always move it somewhere else if it does.
