Senecio anteuphorbium Swizzle Sticks

Swizzle Sticks earns its name from its cylindrical, upright stems that resemble swizzle sticks, growing in tight, sculptural clusters. The stems are smooth and dusty grey-green with a waxy texture and subtle segmentation along their length. Its upright growth style creates an architectural form that stands apart from most other succulents in a collection.

It produces small, daisy-like white to pale yellow flowers when given a night temperature drop, typically in cooler months. Blooms appear when the plant is placed near a cool window in autumn and winter. Its deep root system anchors it well and supports the upright stems through the flowering period.

Move it outside for summer in a bright, sheltered spot and bring it back indoors before temperatures drop toward frost. It needs cover from heavy rain to protect the roots from waterlogging. Keep this succulent on a high shelf well out of reach, as the sap can cause skin and paw irritation in cats, dogs, and small children.

Water it deeply every 10 to 14 days in summer, then cut back to once every three to four weeks in winter.

Swizzle Sticks does best in a gritty, fast-draining cactus and succulent mix blended with extra perlite or coarse sand.

It prefers temperatures between 50 and 85F and must be brought indoors before frost threatens, as it is not frost tolerant.

Swizzle Sticks is a slow to moderate grower that benefits from diluted balanced fertilizer applied once monthly during the active growing season.

It is hardy in USDA Zones 9 through 11, where winter temperatures rarely drop below 25F. It grows outdoors year-round across California, Arizona, Texas, Florida, Hawaii, Nevada, Louisiana, Mississippi, Alabama, Georgia, and South Carolina. Coastal areas of Oregon, warmer pockets of North Carolina, and sheltered microclimates in New Mexico and Arkansas can also support it with minimal winter protection.
