Walters Gardens Exclusive Introduction

From the Walters Gardens, Inc. hybridizing program comes our darkest red flowered selection to date.

Near-black, glossy, pointy buds open to lustrous, dramatic deep red blossoms with a blackish red center and veining.  Bright yellow pollen on the red anthers in the center of each blossom pops with contrast.  The 8-10” wide blossoms have rounded, overlapping petals with a hint of ruffling on the edges. 

‘Heartthrob’ forms a compact, well-branched, rounded clump of mid-green, hydrangea-like leaves.  At just 4’ tall, it fits nicely into the back of the border and offers outstanding late summer interest.

Homeowner Growing & Maintenance Tips:

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.
