Euphorbia mammillaris

Phonetic Spelling
yoo-FOR-bee-uh mam-mil-LAIR-iss
Description

Indian Corn Cob is a succulent columnar, cactus-like plant studded with occasional spikes that resemble toothpicks. They are drought tolerant and need great drainage. Water once a week in the summer and up to once a month in the winter, allowing the soil to fully dry out between waterings. With plenty of space and sunlight, Indian Corn Cob can reach 1 foot tall and sprout new branches from its base. 

Plant in containers with good drainage holes in potting soil appropriate for succulents and cacti. Provide with sun outside and bright light inside.
