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 its 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.

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 doesnt need to be deadheaded and shouldnt need much in the way of fertilizer either shes a very self-sufficient gal. While you shouldnt 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.
Diamond Frost is moderately salt tolerant - it can withstand the amount of salt encountered when planted 30 feet or more from the source of the salt.
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.
