euphorbia rainbow ascot

last year

Anyone have these ? I planted 4 and recently redid the bed they were in. I have them sitting in the soil waiting to be moved now. Most of the videos I watched about them were in the UK area. I bought these because there is a house in my neighborhood that has them and they look good most of the year. Didn’t find much about them in any forums. Curious of locations and soils they thrive in?

I am a huge fan of hardy euphorbias and have grown many species myself as well as spec'd them in countless client designs. Many behave more like a subshrub rather than a herbaceous perennial, retaining stems and foliage throughout the year. Ascot Rainbow is a selected form of E. x martinii, a naturally occurring hybrid of of two very tough species. Like the majority of its cousins, AR prefers full sun and a lean, well drained soil.

Flowers form in very early spring at the terminal ends of the stems produced the previous season. Once a stem has flowered, it will not do so again and should be removed at the base. One needs to be careful not to damage new shoots that will be present at that time as well as avoiding contact with the caustic sap - latex - that will appear from any damaged or cut stems.

Awesome thanks ! Had them in a partly shaded corner. Was shocked how easy they came out and they were root bound. Cleaned up the roots and put them in full sun in an area with better drainage. Don’t see these around too much. From my understanding they are rather easy once established.

Dead easy in my climate. 😁 In fact, while I have not experienced it with AR, other forms of xmartinii will cross pollinate with several other euphorbia species as well as reseed quite freely.

Awesome! Do you have a big property? I feel like you know a little something about every plant !

Thanks, James. I'll take that as a compliment. 😄

No, I don't have a big property, never have. In fact, my garden now is tiny. But after nearly a half century of gardening both personally and professionally, I have encountered a whole lotta plants! Some only lasted a season or two if I decided their attributes were not sufficient to make them a long term garden resident and they were replaced with something different. But I have always been a plant geek and in my area, you can grow just about anything so lots of choices to trial. It also helps that I worked in the nursery industry for many years as well as a long career as both a garden designer and horticultural consultant. After this many years, you just pick stuff up!
