Euphorbia lactea – Mottled Spurge / Dragon Bones Tree

This succulent's strikingly patterned stems help it immediately stand out. While it is not technically a cactus, is is that sort of shape, with spikes running up and down its stems and 'arms' branching out to the sides. And, like a cactus, it will be happiest in a sunny window with plenty of time for the soil to dry out between waters. Tolerant of forgetful waterers, this low-maintenance beauty will be a real structural statement piece in your home.

Scientific Name
Euphorbia lactea (Euphorbus' milk-white plant)

This plant has had the same scientific name since it was first published about in an 1812 paper.

Common Name(s)
Mottled Spurge, Dragon Bones Tree, Candelabra Spurge, Mottled Candlestick, Milkstripe Euphorbia, False Cactus

Origin
This plant is native to Sri Lanka, Asia, where it grows in seasonally dry tropical areas.

Light
This plant likes plenty of bright light, and will benefit from a few hours of direct sun each day. You can build up its tolerance to direct light by introducing it gradually, but it won't need or want more than four hours of direct sun.

Water
Let the soil dry out completely between waterings. Water thoroughly, allowing excess water to drain away. Don't let the soil be constantly damp, especially during winter when the plant is dormant. Reduce watering frequency significantly in cooler months.

Humidity
Prefers low-humidity environments. Avoid placing it in rooms with high moisture, such as bathrooms or kitchens.

Soil
Plant in a well-draining cactus or succulent potting mix. Adding sand or perlite will improve drainage. Repot every three or four years in spring as the plant grows - this plant will prefer to be potbound for a while than to be moved before it's outgrown its pot.

Food
Feed every two months in spring and summer; reduce to every three in autumn and winter.

Temperature
Average temperatures of 15-32°C are fine in the growing season. Lower temperatures in winter will help the plant's dormancy period, just make sure it doesn't drop below 12°C.

Pet-safe
No, this plant is toxic to pets and small humans, as well as having sharp spikes! 

Sprouts Top Tips
Be cautious of the sap when handling Euphorbia lactea. If pruned or damaged, the plant will release a sticky, milky latex sap that can irritate the skin. Always wear gloves, and clean tools thoroughly after use. This sap will also prevent pests and diseases from taking hold.
