All About Euphorbia Myrsinites
In the UK, the Royal Horticulture Society acknowledges Euphorbia myrsinites for its exceptional beauty. These succulents grace rock gardens, terracotta pots, or driveways, showcasing a stunning ground cover.
Hailing from Southeastern Europe and Asia Minor, the plant’s gray-green spiraled leaves add to its allure. Blooming with inconspicuous greenish flowers that transform into small sulfur-yellow blossoms, it’s a favorite for its showy yellow bracts.
While acclaimed by the Royal Horticulture Society, cautious cultivation is advised due to its invasive nature in Oregon, Utah, and Colorado. To prevent ecological harm, plant in containers, remove spent flowers promptly, and monitor growth boundaries to contain its spread.
Displaying typical Euphorbia traits, this species exudes a latex sap that can cause skin irritation and is toxic if ingested, posing risks of blindness if in contact with eyes. Protective gear like goggles, gloves, and long-sleeved attire is crucial when handling Euphorbia myrsinites.
Myrtle Spurge Care
Despite its dangers, caring for myrtle spurge is relatively straightforward as long as it’s managed effectively. Let’s delve into the essentials now.
Light & Temperature
Thriving in full sun, this plant favors USDA hardiness zones 5 to 9. While ideal outdoors, for areas where it’s problematic, or in colder climates, indoor cultivation near a sunny south-facing window is an alternative.
Its adaptability to both high triple-digit temperatures and lows down to -20°F contributes to its invasiveness. Established plants require no special protection from extreme climate conditions, yet flourish in warmer winter climates.
Water & Humidity
Drought-tolerant, this succulent demands minimal watering to thrive. Avoid over-watering, as it can prove fatal. Water sparingly, ensuring the soil dries up to a finger’s length before watering, especially during severe droughts. Avoid excessive humidity to prevent water-related issues.
Watering Euphorbia Myrsinites
When watering your plant, wet the leaves and water slow and low in the morning whenever possible.
Soil
Well-draining sandy or gravelly soil suits your plant best, avoiding overly nutritious soil. For enhanced drainage, mix coarse gravel or sand with pre-formulated cactus soil.
Fertilizer
Fertilizer is usually unnecessary for this plant, especially in areas where it thrives in low-quality soils. Avoid fertilizing in regions where it’s classified as an invasive species.
Repotting Euphorbia Myrsinites
When repotting, move your plant to a slightly larger container with proper drainage if it outgrows its current one. Use coarse potting mix and ensure your plant remains at the same level during the transfer. Water lightly and place in full sun to establish new roots.
Myrtle Spurge Propagation
Propagate your plant through seeds or cuttings during the growing season. Wear protection when handling the plant due to its saponin content. Dip cuttings in rooting hormone and plant in coarse potting mix for successful root development within weeks.
Pruning Your Euphorbia
Prune your Euphorbia myrsinites after blooming to control its invasive nature. Trim back stems and remove spent flowers before they disperse seeds. Clip yellowing blooming stems to maintain plant health.
Troubleshooting Euphorbia Myrsinites
Growing Problems
Manage your plant’s growth to prevent overtaking your garden by timely pruning. Avoid over-watering to prevent root rot and ensure plant longevity.
