Slender-Leaf Senecio is a slender, hairless, much-branched annual herb, usually about 15-45 cm tall. The leaves are stalkless and pinnately cut. This is such a useful succulent. The linear foliage gives the garden a shot of blue all year long. The texture & color combine well with many plants. Try it with Asclepias currassavica Silky Gold for a blue & yellow garden or combine with lime green Crassula lycopodiodes for a cool color scheme. Grows to about 1 inch high & about 3 inch wide. Clip to keep compact. The flowers are inconspicuous, but S. madraliscae makes an excellent foliage plant. It can be grown as a trailing plant in a container.
Water the plant only during dry summer weather. Blue finger is a drought-tolerant succulent that can survive long, dry periods. Watch for signs that the plant needs water, especially leaves that begin to look shrunken or wilted. Water the plant s site deeply, and then allow the soil to dry completely before watering again.
Stop watering the plant in late summer or early autumn. Withhold water completely during the winter months. Damp, cool soil places the plant at risk for stem rot.
