Euphorbia cyparissias

Loxley

I planted some last year, and it's spread a bit, popping up here and there. It looks nice now but I'm slightly concerned it will become invasive in my narrow (50cm) wide border. Dryish rich and free draining soil. Should I pull it out? I want to plant some Sedums in the same bed so am delaying planting them until I've made my mind up!

I would keep some of your E.cyparissias , even though it spreads seemingly everywhere by underground rhizomes . 'Fens Ruby' is a reddish tinged form , quite nice really !
What about lifting a portion out of the ground and confining it to a small trough or something similar , the get rid of the rest from your border ?

I have this and quite like it, but I think it depends on your planting style. It does pop up all over the place, making its own planting combinations, but is easy enough to remove if unwanted in a particular spot.

We had this at our old house, it was a nightmare! It is nice when it stays where you want it so I'd do what Paul suggests.
