Bigger, bushier, and breathtaking, Diamond Mountain® Euphorbia makes a massive statement in the garden! Diamond Mountain® Euphorbia has all of the same perks as Diamond Frost® Euphorbia but it is the big brother version. Clusters of white flowers and wispy green foliage, make a beautiful display from spring to fall. This plant has a mounding habit that reaches 36 inches in height and spread. Diamond Mountain® Euphorbia contrasts very well with other broad-leaved vigorous plants making quite an impression.

Don’t be fooled by it’s dainty, sweet appearance. Diamond Mountain® Euphorbia is a tough and dependable workhorse all season long. This plant is no match for summer heat, drought, or deer. Deadheading is not even an issue. It looks amazing as a filler when used in a container. When used in the landscape, Diamond Mountain® Euphorbia creates a stunning backdrop of white and green wispy frills that mimic paint on a canvas.

Diamond Mountain Euphorbia Care

This euphorbia is adaptable and versatile in every corner of the landscape. It does well in a wide range of sunny to shady locations, requiring at least 4 to 6 hours of sunlight daily. It has average water needs. Soil needs to be moist and well-draining for best results, but once established no supplemental irrigation is needed. This plant can be trimmed anytime, but it is unnecessary. Flowers are self-cleaning and will rebloom profusely. Apply an annual application of compost or fertilizer in the garden beds and fertilize regularly when planted in containers.

Plants in the Euphorbia family have milky latex sap that may irritate the skin. Be cautious when handling euphorbia especially if sensitive skin or latex allergies are a concern. Diamond Mountain® Euphorbia is an annual grown outside in zones 9 and below. It is hardy to zones 10 to 11. This plant does not do well overwintering and dies after a hard frost.

Diamond Mountain Euphorbia Spacing

Space Diamond Mountain® Euphorbia 12 to 18 inches apart in both the landscape and container planting. Usually, the bigger container size is preferred. A pot 12 to 16 inches is adequate.

    Fabulous reliable plant

    Posted by Nomi Lubin on Oct 23rd 2021

    I can't say enough about Euphorbia Diamond Mountain. After it puts on some size, it looks like this picture the entire season. I find it doesn't need fertilizer, and can take fairly dry conditions. I actually cut it way back and take it inside in the winters (I'm in zone 7A) and keep it small (a lot of pruning!) under grow lights, then plant it out again in the spring.
