Blooming in mid to late summer, these showy flowers create a dramatic contrast in gardens, providing architectural height and an old-world charm to borders and cottage gardens. Typically reaching 5-8 feet in height, Black Hollyhocks thrive in full sun and adapt to a range of soil conditions, from normal to sandy or clay types, with a preference for well-drained soil. While rust can be a challenge, especially in humid climates, this plant remains attractive to pollinators like butterflies and hummingbirds, contributing to the biodiversity of the garden space.\u003c\/p\u003e\n\n\u003cp\u003eHardiness Zone: 3\u003cbr\u003e\nStratification: none required\u003c\/p\u003e","brand":"Oak Summit Nursery","offers":[{"title":"Default Title","offer_id":43388451487902,"sku":"","price":5.95,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0520\/5675\/2286\/files\/il_fullxfull.5873883800_mgk0.jpg?v=1711505812","url":"https:\/\/oaksummitnursery.ca\/products\/black-hollyhock-alcea-rosea-nigra-biennial-flower","provider":"Oak Summit Nursery","version":"1.0","type":"link"}
