Characteristics
Snow on the Mountain grows up to 3 feet tall with numerous branches. The young leaves are green, but as they mature, they develop striking white margins and may even turn entirely white. In summer, small greenish-yellow flowers form, highlighted by bright white bracts. Although the flowers themselves are not show-stopping, the bracts make an attractive display. A word of caution, the sap from the plant can cause irritation to your skin, so protect yourself when working with it. Use it as an eye-catching ornamental, in meadow plantings, or in containers. With its vertical growth habit, it also serves as an ideal groundcover that attracts pollinators and conserves moisture.
Light
This hardy plant hails from the prairies in regions such as Minnesota, the Dakotas, Colorado, and Texas. It thrives in areas with at least 6 hours of sunlight. However, it prefers some shade during the harsh midday sunlight to help prevent the stems from getting leggy.
Water
Euphorbia Snow on the Mountain can adapt to either moist or dry conditions, as long as the soil is well-draining. Provide regular water to newly installed plants or seedlings until they've developed a good root system.
Temperature & Humidity
Euphorbia enjoys temperatures between 65-80°F (18-27°C), although they can tolerate a range of conditions. Keep in mind that the plant will start to die back as the fall cools.
Soil
This variety is tolerant of clay, limestone, sandy, chalky, and loam soils. In their native environment, they can excel in poor, rocky soil with little nutrients.
Fertilizer
Fertilizing isn't necessary, but if you want to enhance the growth of those beautiful leaves, give your Snow on the Mountain a spring application of nitrogen plant fertilizer. Excessive fertilization will just lead to lanky growth.

Problems, Pests & Diseases
The Snow on the Mountain plant doesn't have many serious pest or disease issues. Be cautious when planting it in boggy sites, as poor drainage can lead to root rot in garden plants. Although aphids can be a problem, they are rarely seen on the Snow on the Mountain. The sap is highly irritating, so be sure to use gloves when handling the plant. Mourning doves enjoy the seeds, but neither animals nor humans should consume the plant as it's toxic. Local honey bees that gather nectar from this plant may create a unique "jalapeño honey" due to the stinging sensation it gives to the throat.
How to Plant Snow on the Mountain
Plant Euphorbia marginata in a well-draining soil, either in the ground or in containers. Ensure the soil remains moderately moist while the plant is establishing.
Pruning
Only prune damaged stems on the Snow on the Mountain. In areas where the plant has a tendency to seed excessively, remove the flowers to prevent seed set.
Propagation
Directly sow the seeds in the ground, or start them indoors 6-8 weeks before the last expected frost. Expect germination in 10-14 days in soil maintained at 65-75°F (18-24°C). Since germination might be unreliable, it's better to plant more seeds than the number of desired plants.
Is the Snow On The Mountain Plant Invasive?
In optimal conditions, the Snow on the Mountain will enthusiastically self-seed, possibly becoming a nuisance in your garden. To prevent overgrowth, consider pruning off the flowers as they appear to manage its spread. In non-native environments, it might be classified as invasive, especially in areas with similar climate and soil conditions. Always check local guidelines and research the potential impacts before planting.
How to Get Rid of Snow on the Mountain
If you find that the Snow on the Mountain has invaded your garden, use a foliar herbicide or intimate hand-weeding to eradicate it from the space. Introduce a surfactant to the herbicide mixture to ensure that the leaves are evenly coated. Another alternative is to cover the area with black plastic for several months to kill off the plants.
