Euphorbia – Diamond Frost^®

Diamond Frost is like your friend who gets along with everyone she meets—it combines easily with many kinds of plants, weaving its wiry stems in and out, poking its single, airy white flowers throughout the combination. Often imitated but never equaled!

I want to thank my parents, my breeder, and especially the millions of fans who have made me the Most Award Winning Plant in Proven Winners History. At my 2005 debut I was just a new, 12 -18 inch Proven Winners Euphorbia. I never imagined my career would last. I suppose it's because of my annual nature (except in zones 10 - 11). At first, I thought you liked me solely for my incredible, continuously blooming clouds of airy white flowers. But as I grew in more containers and landscapes across North America, you praised my mounded habit, and how well I tolerate heat and drought. My versatility both as a single and in combinations. Others spoke of how easy I am to grow. In letters you wrote of my ability to stay beautiful without deadheading. And I was deeply touched by your appreciation of my deer resistance.

Without you, I would still be just another plant in the unforgiving world of commercial horticulture. If I could, I would keep you with me in the full to part shade forever.

Maintenance Notes

Diamond Frost might look delicate and frilly, but nothing could be further from the truth. Diamond Frost is actually pretty much tough as nails. She has performed well from North to South and coast to coast. While she does best in sun or part sun conditions, she does surprisingly well in shady conditions also. As you might suspect she is great in mixed containers and containers by herself, but don't discount her excellent performance when planted in the landscape. She needs little to no supplemental water and is extremely heat tolerant. She doesn't need to be deadheaded and shouldn't need much in the way of fertilizer either - she's a very self-sufficient gal. While you shouldn't need to trim her back, you can trim her back at anytime and she will just keep doing her thing. Diamond Frost is one of my all-time favorite plants.

Self-cleaning, no deadheading necessary.

Some shedding of flowers and leaves may occur indoors depending on light levels and watering.

Plants in the spurge family often will bleed a milky, white sap if cut or wounded. This sap is a form of latex. Most people will have little or no reaction due to sap exposure from the euphorbia that Proven Winners sells. However, people with sensitive skin or latex allergies should be cautious when handling euphorbia. Poinsettias are in this same family. If you have ever experienced a skin irritation due to contact with poinsettias you should be cautious with all euphorbia.

An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Pinching and Growth Regulators

No Pinch necessary but plants can be pinched to shape. A very soft pinch or a shearing off of just the growth tips will encourage fuller growth. A hard pinch can stall growth. Diamond Frost and Diamond Delight are very sensitive to Florel. Florel will cause defoliation.

Pest and Disease Management

General pest and disease practices. Good sanitation practices include keeping greenhouses clean at all times, eliminating weeds and debris, disinfecting equipment in greenhouses as often as possible and keeping hose ends off of the greenhouse floor. Good water management practices are critical for good, healthy plant growth.
