General Culture:
Winter hardy to USDA Zone 10. DIAMOND FROST is grown in most of the U. S. including the St. Louis area as an annual. It performs well in dry to medium moisture, moderately fertile, well-drained soils in full sun to part shade. Soils must be sharply drained. Allow soils to dry before rewatering. Moist soils and/or over watering can be fatal. Plants generally have good heat and drought tolerance. Site plants in containers or in the garden. Garden plants may be spaced 10”-12” apart. Containers may be brought indoors before first fall frost for overwintering in a sunny window where they may continue to flower. Cut back stems and take containers outdoors in spring after last frost date. Many gardeners simply repurchase new plants each spring.
Noteworthy Characteristics:
‘Inneuphe’, commonly sold under the trade name of DIAMOND FROST, is a vigorous spurge that produces a profuse, non-stop bloom of tiny white flowers from spring to frost. Plants typically grow to 12-18” tall on generally upright stems clad with gray-green leaves. Tiny white flowers reminiscent of gypsophila (baby’s breath) bloom freely. This plant is sometimes listed as a cultivar of Chamaesyce hypericifolia. U.S. Plant Patent Applied For (PPAF).
Problems:
No known serious insect or disease problems. Root rot may occur in poorly drained or wet soils. Watch for aphids, mealybugs and spider mites. If sensitive to the toxic plant saps of euphorbias, it is best to use gloves when working with this plant.
Uses:
Abundant bloomer for landscape areas, border fronts, hanging baskets and containers. May be grown as a houseplant.
