Euphorbia marginata ‘Mountain Snow’ | Snow-on-the-Mountain | Seeds

Euphorbia marginata ‘Mountain Snow’, commonly known as Snow-on-the-Mountain, is a striking ornamental annual valued for its dramatic green leaves edged with bright white margins that resemble freshly fallen snow.

This unique plant creates a light, airy effect in flower beds and borders. During summer, plants produce small white flowers surrounded by decorative white-variegated bracts, giving the entire plant a luminous appearance.

Plants grow quickly and form tall, branching stems that are excellent for cut flower arrangements and bouquet fillers, adding texture and contrast. The unusual foliage makes it especially popular in wildflower gardens, cottage gardens, and cutting gardens.

Euphorbia marginata is easy to grow and tolerant of heat and drought, thriving in sunny locations with well-drained soil.
