Showy Dandelion Plant Care
Malacothrix indecora Greene
Updated · Sources · How we source care data
Malacothrix indecora is a rare species of flowering plant in the family Asteraceae known by the common name Santa Cruz Island desertdandelion. It is endemic to the Channel Islands of California, where it is known from only a few populations on three of the eight islands. As of 2000, there were three occurrences on San Miguel Island, two on Santa Rosa Island, and one on Santa Cruz Island. It grows on the bluffs and rocky coastal grasslands of the islands. Like many Channel Islands endemics, this plant is naturally limited in distribution and has been threatened by the presence of destructive introduced mammals, in this case, feral pigs. The plant became a federally listed endangered species in 1997. This is a mat-forming annual herb which spreads low to the ground no more than about 10 centimeters high. The fleshy leaves have dull lobes. The inflorescence is an array of flower heads lined with oval-shaped phyllaries. The ray florets are under a centimeter long and yellow in color.

What Soil Mix Works Best for a Showy Dandelion?
Well-draining sandy soil with some organic matter. Good drainage is essential for Showy Dandelion to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Showy Dandelion?
Feed Showy Dandelion every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs in good soil often need little extra feeding, so let weak growth or pale foliage guide you.
Stop feeding by late summer so new growth can harden before winter.

The PlantoScan app can remind you when to water and when to fertilize each plant.
Where Should You Plant a Showy Dandelion?
Choose a spot with full sun and well-draining sandy soil with some organic matter. Avoid low spots where water collects after rain.
Showy Dandelion is suited to USDA Zone 12a.
Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Showy Dandelion?
Showy Dandelion can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Showy Dandelion?
Prune Showy Dandelion while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.
How Do You Care for a Showy Dandelion in Winter?
Showy Dandelion is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.
How Do You Propagate a Showy Dandelion?
Showy Dandelion can be propagated through seeds. Similar propagation techniques also apply to coulter's malacothrix plant care, which shares the same genus.
