Mountain Crest Gardens Euphorbia mammillaris

No, this plant is not pet-friendly. It contains a white, latex-like sap that can be toxic if ingested and may cause skin or eye irritation upon contact, so it is best kept out of reach of curious pets.

To keep its distinct white, blue, and pink coloration, this plant requires bright, direct light. A sunny, south-facing windowsill is ideal; without enough light, the plant may lose its vibrant variegation and begin to stretch or etiolate.

This is a drought-tolerant succulent that prefers to dry out completely between waterings. Plan to water roughly once a week during the active growing season in summer, and reduce this to about once a month during the winter dormancy period.

It is a slow-growing variety that typically reaches a mature height of about 12 inches. Because of its vertical, columnar growth habit, it remains compact and is well-suited for small spaces or windowsills for a long time.

Excellent drainage is non-negotiable for this plant. Use a well-draining cactus or succulent potting mix and ensure your pot has a drainage hole to prevent water from sitting at the roots, which can lead to rot.
