Learn more at How to Grow and Care for Senecio. Cut during the growing season, from early spring to fall-root in sandy soil in containers. Using cuttings is an easier and faster method for propagation. Seeds prefer warm temperatures and constant moisture to germinate. Senecio can be grown from either seed or cuttings. Wait until there is no danger of frost and move them back indoors in the fall. If you are growing them in containers, they enjoy spending the summer outdoors. Plants can be divided or repotted in early spring. You can prune them back to where the stem is firm in very early spring. Too much fertilizer will cause a lot of leggy growth. Since they are growing in sandy soil, nutrients will need to be replenished. Allow the soil to dry out between waterings in winter, when they are somewhat dormant. They need some water during the summer but do not leave the soil wet for prolonged periods. How to Grow and CareĮstablished Senecios are extremely drought tolerant. It is present in most of the eastern states, including those bordering the Mississippi River, as well as Texas, Oklahoma, and Kansas.USDA hardiness zones 9b to 11b: from25 ☏ (-3.9 ☌) to 50 ☏ (+10 ☌). This species likes sand and grows in both prairies and open woods. Ironically, this plant was used by Native Americans as both a love charm in food and as a poison used to against their enemies, as this species is known to have toxic properties. Seeds are contained in a chambered capsule with two divisions, and once ripe, the capsules split open and wind action helps scatter the up to three hundred seeds within each capsule. ![]() Although seeds can germinate the same season as when they are released, usually they germinate the following spring and produce a basal rosette that will flower the following season. Also, the lack of a lower petal lip denies insects a perch to rest on, favoring hovering organisms like bees and hummingbirds. Hummingbirds have long bills that allow them to reach the nectar rewards at the end of long, tubular flowers. However, like most red flowers, this species is especially adapted for pollination by hummingbirds. This is somewhat surprising since the color red is difficult for insects to see. Castilleja coccinea, commonly called Indian paintbrush or painted cup, is a biennial member of the broomrape family (Orobanchaceae) that typically grows on unbranched stems to 1-1.5' tall (less frequently to 2'). A variety of insects visit paintbrush flowers, especially bees. Despite being obligate parasites for part of their lives, these plants do rely on pollinators for reproduction. These plants are hemiparasites, meaning that although these plants are green and can photosynthesize, they also have the ability to sequester nutrients from other organisms, in this case, from perennial grasses. lutescens), as well as a separate closely related species that also has yellow bracts ( Castilleja sessiliflora). Also, there is a form of this species that has yellow bracts ( Castilleja coccinea f. The actual flower petals are rather inconspicuous, although the tip of the sepals are tinged with red as well. The showy red structures are technically bracts, a type of modified leaf, and not petals. The genus name “ Castilleja” is named after Spanish botanist Domingo Castillejo, and “ coccinea” means “red,” referring to the red bracts that surround the flowers. This plant is also called painted cup for the showy cup-like bracts. This species was formerly placed in the Figwort family (Scrophullariaceae), which was a hodgepodge of genera that didn’t fit well in other families. ![]() ![]() Indian paintbrush is an attractive member of the parasitic Broomrape family (Orobancaceae). ![]()
