Alcea Rosea Nigra

    Butterfly IconHummingbird Icon

    Plant Type: Perennials

    A novelty selection that is a must have for collectors! Single, deep chocolate-maroon (nearly black!) flowers are produced on tall, strong stalks, opening from the bottom up over a long period in summer. The leaves are deeply lobed in classic Alcea form. Feel free to grow hollyhocks under Black Walnut trees; they are tolerant of the toxic juglone that is emitted through the trees' roots.  Hollyhocks are best treated as a biennial or short lived perennial, but will sometimes reseed themselves for many years.

    Growing & Maintenance Tips:

    Hollyhocks provide excellent architectural height in the garden and make good backdrops for lower growing perennials. Try growing them in the cottage garden style by planting them up against a wall or picket fence. Though their stalks are very strong, they may need to be staked if they are planted in a windy site. Hollyhocks prefer rich, moist, well-drained soil but can tolerate short periods of drought. They need full sun to really perform in the landscape. Watch for Japanese Beetles; this plant is one of their favorite! Feel free to grow hollyhocks under Black Walnut trees; they are tolerant of the toxic juglone that is emitted through the trees' roots. Hollyhocks are best treated as a biennial or short-lived perennial.
