Euphorbia
Summer to Fall Frost: Another outstanding and popular annual flower is euphorbia. In bloom, this plant creates a blizzard in a pot. In the landscape, plants form a rounded mound of solid white. This is a heat and drought tolerant annual, and it also gives deer, rabbits and groundhogs the brush off. It’s not just a popular annual — it’s tough, too. Shown here is the award-winning variety 'Diamond Frost.'
