Product Description
Hibiscus 'Mars Madness' PP27838 (25) Bare Root Plants
Common Name: Rose Mallow
This Walters Gardens Hibiscus introduction is out of this world with its unique foliage and flower color combination. Dark olive green leaves have copper highlights, with the newest leaves emerging coppery purple. The large, maple-like leaves are broadly smooth and form a full, billowy habit. Huge 6-8” flowers open flat and are magenta red in color, more on the pink side of the spectrum than ‘Cranberry Crush’. Each flower has a small, darker red halo with overlapping petals and deeply impressed veins. Flowers are produced from the top to the bottom of the plant, rather than only at the top like some older cultivars.
‘Mars Madness’ is a later blooming Hibiscus and will extend the color of your late summer - early fall garden.
These North American native plants bring massive, tropical-looking flowers all the way to zone 4. Although later to emerge than most perennials in spring, these are fast growing plants capable of adding an inch of new growth a day. Excellent at brightening up end of season gardens.
Hibiscus love the sun and need moist, well-drained soil. Keeping these plants watered will result in larger flowers and lush foliage. Deadheading will improve the appearance of the plant. It is best to plant Hibiscus in the garden before the heat of the summer arrives and should be heavily mulched the first winter. In spring, cut back any remaining stems before new growth appears. A strong pair of loppers or a saw will be necessary to cut this plant back. Be advised that Hibiscus is always one of the last perennials to emerge in spring. Its vigorous growth rate more than makes up for this late start, however. Japanese beetles find these plants especially delicious.
