Euphorbia tirucalli features slender, cylindrical stems that resemble pencils, hence its common name. The stems are typically green, but the "Firesticks" variety displays shades of yellow, orange, and red. This Euphorbia produces small, inconspicuous flowers at the tips of its stems, but it is primarily grown for its unique foliage.
- Water sparingly, allowing the soil to dry out completely between waterings. Pencil Cactus is drought-tolerant and can withstand periods of dryness. It's best to err on the side of underwatering rather than overwatering, as too much water can quickly lead to root rot.
- To thrive indoors, consistent bright, indirect sunlight with a combination of direct light is best. Southern or western exposures are ideal.
- If you want to place it outdoors during the summertime, it can tolerate full sun but may need protection from intense afternoon.
