Diamond Frost®Euphorbia

Euphorbia hypericifolia (yoo-FOR-bee-uh hy-PER-ee-see-FOH-lee-uh)

Family: Euphorbiaceae Unknown Herbaceous (1-3 ft)

The cultivar 'Inneuphida' is commonly sold under the trade name of Diamond Frost®. It is from the species Euphorbia hypericifolia and is evergreen perennial that is usually grown as annual. It was discovered in 2004 in Gensingen, Germany in a group of Euphorbia hypericifolia plants. It differs from the parent plant by having a more uniform appearance, more branching, more flowers, and smaller flowers. It grows 12 to 20 inches tall and has a mounding habit. Plant in full sun to partial shade in well-drained soil. They are quite drought and heat-tolerant and are resistant to browsing by deer and rabbits. These low-maintenance plants require no deadheading to enjoy a long bloom season. Pinch to encourage a bushy habit especially if they are grown in containers. They are hardy in zones 10 to 12. The stems are erect and have widely spaced leaves of grayish-green to bright green. Tiny white bracts are present from spring until the first frost of fall. Diamond Frost® is infertile and does not produce seeds. Wear protective gloves when handling these plants due to the toxic milky sap. Keep these plants out of reach of small children and pets. All parts of the plant are toxic if ingested. Plant these groundcovers in containers, in cottage gardens, or in drought-tolerant gardens. The delicate flowers make a delightful addition to a fairy garden. It is attractive in containers or hanging baskets that are used to line a walkway or border front. It can also be grown indoors as a houseplant. Insects, Diseases, and Other Plant Problems: No significant problems.
