Senecio crassissimus, also called Vertical Leaf Senecio, is a drought tolerant succulent native to Madagascar. A member of the Senecio genus in the Asteraceae family, it grows well in the dry, rocky landscapes where it originated and brings that same architectural presence to any home or collection. It adapts well to indoor windowsills and outdoor patios.
Its upright paddle-shaped leaves grow perpendicular to the stem, stacking like silver-green propellers along each branch. The leaves are thick, waxy, and edged with a purple-violet outline that deepens when exposed to brighter light. Its upright, columnar growth habit gives it a geometric, sculptural form.
Small yellow daisy-like flowers appear in late winter to spring when the plant reaches maturity, typically triggered by cooler night temperatures in autumn and early winter. Move it to a slightly cooler location in the evening during this season to encourage blooming. The plant produces pollen and allergens, so it may affect anyone in your home with sensitivities.
It tolerates dry heated air well and handles periods of drought without extra attention. You can leave it up to ten days without water. Move it outside in summer to a bright, sheltered spot, keeping it covered from heavy rain. The sap can cause skin and paw irritation, so keep it on a high shelf away from cats, dogs, and small children.

Vertical Leaf Senecio - Senecio crassissimus grows well in bright indirect light to full sun, ideally near a south or west-facing window. Rotate it regularly for even, upright growth on all sides.
Water it every 10 to 14 days during spring and summer, then cut back to once every 3 to 4 weeks in winter, allowing soil to dry completely between waterings.
Senecio crassissimus does best in a fast-draining cactus and succulent mix blended with extra perlite or coarse sand to prevent root rot.
It prefers temperatures between 60 and 85°F and should be brought indoors before temperatures drop below 40°F, as it does not tolerate frost.
