Growing Zebrina Zebra Hollyhock Seeds
Plant Zebra Hollyhock Seeds: Sow zebra hollyhock seed in 2 in. pots or cell packs, press into soil and lightly cover. Kept at 70-75° F., germination is in 14-28 days. Can direct sow seed into prepared seed beds after all danger of frost, in groups of 3-4 seeds spaced 12-24 in. apart. Thin to the strongest plant.
Grow Zebra Hollyhock: Full or part sun. Zebra hollyhocks tolerate a wide range of soils as long as drainage is good. Once established, plants are drought tolerant; bloom will be heavier with moderate to average water. Feed with all-purpose fertilizer before growth begins in spring. Flowers are excellent for cutting, attract butterflies and hummingbirds. Remove old blooms, or cut plants back to encourage repeat flowering.
Zebra Hollyhocks are rugged; we have seen them sprout in the cracks of our sunny concrete patio, survive the season, throw out a few blooms, manage to live only on the soil left behind by our push broom, and occasional run-off from lawn sprinklers. In more ideal locations, with only modest attention, zebra hollyhocks will reward you with a long season of colorful bloom.
