A few years back Proven Winners sent me a new euphorbia (Euphorbia graminea) to try called Diamond Frost. Although it is listed as an annual, it is really a tender perennial. I still have that original plant because I winter it in my attached garage. It now fills a large container.

I love using it alone since white floating over green is so soothing and cooling in summer. It also makes a good foil for other annuals in containers. It acts just like baby’s breath in a flower arrangement, adding an ethereal quality and lightening the arrangement.

In 2012, Diamond Frost won awards from ten universities scattered over the United States, a testament to its heat and drought hardiness in all climates. It is also readily available at garden shops. Deer do not like it, you don’t have to deadhead it, and it takes very little water to keep it looking perfect. You can grow it as a houseplant because it will take part shade as well as sun, which adds to its must-have qualities.

This year the mail brought a new Euphorbia graminea from Proven Winners called Diamond Delight. I didn’t think Diamond Frost could be improved upon but I was so wrong. Diamond Delight is a puff of double white flowers floating in a container. The double flowers are even showier than the original. It retains all of the wonderful qualities of Diamond Frost, with bigger and more flowers.

Euphorbia graminea ‘Diamond Delight’ is not available for purchase this year. Look for it next spring. I predict it will become a favorite in your garden, too.
