If you purchase a large plant with a planter, the planter will ship separately

Care Guide
African Milk TreeCentral Africa
Plant Care
Thrives in bright direct light, but can tolerate bright indirect light.
Water every 2-3 weeks in direct light, allowing soil to dry out between waterings. Expect to water more often in brighter light and less often in lower light.
The African Milk Tree may have spiky edges and a tall, column-like shape, but it’s a succulent, not a cactus. The key difference? Unlike cacti, it doesn't grow areoles (those little bump-like structures where spines emerge), proving looks can be deceiving!
Sad Plant Signs
Wrinkled, dry potting mix:
Thirsty plant, underwatered
Blanched center:
Needs more sunlight
Yellowing stems, wet potting mix:
Root rot, overwatered
