    Nursery contributed plant descriptions

    The flowers of this hollyhock are so dark that only when you look at the flower petals backed by sunlight can you see that they are darkest red, otherwise they look jet black. Hollyhocks are a classic cottage garden plant great for the back of the border. They should be grown in full sun with average to fertile soil and good air circulation to help minimize the possibility of rust that can affect the leaves. Plant something full and bushy in front and no one will notice if you do get a little rust! Photo courtesy of Walters Gardens.

    Glowing with the deepest maroon color, these saucer-shaped single flowers look lovely paired with red hollyhocks and yellow flowers. An antique variety which was grown by Jefferson at Monticello. Summer bloom. Rich, moist soil. Biennial to short lived perennial.

    Classic hollyhock with dark maroon, nearly black flowers covering the 5-8 ft spires in July and August. They like well-drained soil and full to part sun with average summer water. Short-lived, they reseed easily establishing long-lived colonies. Frost hardy in USDA zone 2.

    Large & luscious silky black blooms to 4” across, centered with a ruby ring will be THE focal point in your garden, especially since they're so long blooming on their 8' tall stalks. I grew these with Verbascum 'Southern Charm', Salpiglossis sinuata 'Chocolate', Nicotiana 'Lime Green', Orlaya grandiflora, & Hollyhock 'Double Apricot'. Smashing! if I do say so myself! Rich soil is best. Blooms first year & self-sows!
