Euphorbia hypericifolia ‘Diamond Frost’
Annuals, Ground covers, Perennials, Flowers
Diverse genus of about 2,000 species, ranging from small flowery annuals to sculptural trees. The flower is technically a cyathium, consisting of fused bracts that form a cup around the much-reduced true flowers. Cyathia may appear singly or in clusters. In some cases, as with poinsettia (E. pulcherrima), additional bracts below provide most of the color. The fruit is usually a dry capsule that releases seeds explosively, shooting them up to several feet away. Many euphorbias are succulents; these often mimic cacti in appearance and are as diverse in form and size.
All euphorbias have milky white sap that is irritating on contact or toxic if ingested (degree of irritation or toxicity varies, depending on the species). Before using cut flowers in arrangements, dip stems in boiling water or hold in a flame for a few seconds to prevent sap bleed. All need well-drained soil.Euphorbia hypericifolia ‘Diamond Frost’
Perennial in Zones 13, 21–24, H1, H2; grown as an annual elsewhere. Delicate, airy mounds to 12–18 in. high and twice as wide. Small white flowers look like snowflakes interspersed with the sparse, olive green foliage. The plant resembles baby’s breath (Gypsophila paniculata).
