Form: A twining vine.
Leaf retention: Evergreen.
Growth rate: Rapid.
Mature Size: 6-15' long.
Flowers: A large, orange or yellow fluffy disk surrounded by many narrow orange rays bending
slightly backward, 2" wide, fragrant.
Bloom: Spring and summer, sporadically the rest of the year.
Fruit: Tiny, white, tufted seeds forming a ball, usually sterile. These plants are not self-fertile
and two plants are needed to produce viable seeds.
Leaves: Green, highly variable in shape, 2-3 times longer than wide, pointed at tip, thick.
Stems: Green, narrow, rounded. They root at nodes where they touch the ground.
Roots: Fibrous. This plant is invasive when its stems are allowed to touch moist soil.
Wildlife: Attracts butterflies and bees.
Toxic / Danger: No.
Cultivation and Uses
USDA hardiness zones: 9b-13. It dies to the ground below 30°F and comes back from its roots
in winter temperatures above 20°F.
Heat tolerant: Yes.
Drought tolerant: Temperature dependent.
Sun: Full sun for the most flowers.
Water after becoming established: Once a month in winter, weekly in the hottest months of
the year. Only water when the soil is dry.
Soil: Well drained, dry, low in organic content, pH 6.1-7.8 (slightly acidic to slightly alkaline).
Avoid fertilizing because that inhibits flowering and causes aggressive growth. This plant is salt intolerant,
so chemical fertilizers must be avoided.
Mulch: Use organic mulch to shield the roots from winter freezes, especially in zones 8b and 9.
Planting: Can be grown in a container.
Prune: Cut back the tops of the vines to reinvigorate leaves and flowers at the bottom. This
may need to be done twice a year.
Propagation: Cuttings or layering. The seed will not be viable unless derived from two plants.
Uses: Ornamental, butterfly garden. It is best grown on a trellis, fence or draped over a wall
so that the stems do not touch ground.
Senecio confusus is a member of the Aster family (Compositae) and is sometimes designated by
the invalid scientific name Pseudogynoxus chenopodiodes.
This plant tends to lose leaves and flowers from the bottom up, so the vines have to be cut back
to reinvigorate the bottoms.
The best way to prevent this vine from flowering is to  keep it away from full sun,  fertilize it,
or  grow it in overly enriched soil. This is a desert plant adapted to poor soil.
