Has anybody used this plant in borders at all?

I'm thinking of planting it at the front of a border.  Some places say it grows to 1.5m wide ... others say 30-60cm :smile:

Curious as to people's experiences with it.

    there is no limit, it will grow as wide as you let it

    Sounds a bit wild ...

    Try not to snigger ... but will it try to break out of the border and invade the lawn if planted at the front of a bed?

    No, not unless you totally neglect the area for several seasons. It’s a really good plant if you’ve got a place that suits it  :)

    So yeah I think I have a place for it which is a curved border about 4 metres round the  curve.  If I buy young plants in a small 1.5-2 litre pot to fill that space, should I leave big gaps knowing it will fill in?

    In my experience, it can spread into the lawn. This is on heavy clay soil and in shade. Nonetheless, if you want to fill space, this plant will do it, and you can leave reasonably large spaces between them. They should be filled up soon.

    That’s interesting @Borderline because one of my worries was that I have clay soil and this Robbiae variety apparently prefers sand/chalk/loam according to RHS.  

    Did it grow fast for you on clay?  Mine will be in a fairly sunny location with some shade.

    My experience on clay/loam in a fairly sunny west facing border is that if you keep your lawns edged it will stay in the border.  :)

    In a space of around 3 years a 1 litre size plant spread to around 80cm. I would regard that as medium spread. Others may take a different view. I do not mind happy and 'easy' plants. If they are nice looking, I will grow it. I knew what to expect and it did start growing bit into the lawn, but I simply mowed them down and don't have issue weeding them out in the border.

    I planted this Euphorbia Robbiae last October and the plants are starting to grow albeit slowly.  Does anybody know how much you can expect in a season, in terms of spreading across ground?  Or whether it spreads at all during first year?

    It got into to my lawns, spread under the fence  and between paving slabs even though I dug some out each year. I've dug it all out and have the blusters to show for it, even though I was wearing glove I managed to get it on my arm's.
