A Golden Planting Scheme with Euphorbia ‘Ascot Rainbow’ and Carex oshimensis ‘Everillo

In gardening, creating a captivating planting scheme requires careful consideration of various elements. One essential aspect is the foliage of the plants. Today, I want to shine a spotlight on two extraordinary plants: Euphorbia ‘Ascot Rainbow’ and Carex oshimensis ‘Everillo’. These plants not only possess stunning foliage on their own but also complement each other perfectly when planted side by side.

A rainbow of foliage colour

Euphorbia ‘Ascot Rainbow’ truly lives up to its name. With its variegated leaves boasting an array of colors, including vibrant greens, yellow-golds, and hints of deep red, this euphorbia adds a burst of brightness to any garden. Its upright habit and compact size make it a versatile choice for both pots and borders. Moreover, it’s a low maintenance plant that thrives in both sun and partial shade. I love it! I have a number of them planted in the garden, their repeated shape and foliage gives structure to the planting scheme all through the year.

The mass of golden flowers produced in Spring are a bonus, they last for months and I have often seen the plants buzzing with honey bees.

Beside the Euphorbia stands its perfect counterpart, Carex oshimensis ‘Everillo’.

Plant Care Tip

Pruning Euphorbia ‘Ascot Rainbow’: in summer when the main flowering has finished, cut out all the stems that have flowered. This will leave the plant a bit bare for a few weeks, but it will quickly regro shoots from the base to recreate the nica rounded shape.

!!! Wear gloves and long sleeves, keep your skin covered while handling the plant. Euphorbia have a white sap that can cause skin irritation and even blisters during sunny weather. I have never suffered from any ill effects, just don’t get the sap on your skin, and don’t rub your eyes!
