Product Description

Hollyhock Jet Black produces impressive near-black blooms throughout the season! A perfect choice for cottage displays or even just for the flower bed. Grows on elegant tall stems, which makes it a great choice for growing in the back of the border. This variety is a biennial, producing flowers in its second year of growth (but will grow foliage in their first year). Sow seeds inside in trays from March to April or directly outside from May to June.

Growing at a glance…

Sow seeds in small pots or trays from early spring to late summer, ensuring they're kept somewhere warm like a windowsill or heated greenhouse, as this will aid germination. Alternatively, you can sow these seeds directly outside in well-kept soil after all danger of frost has passed (often in May). Push seeds in by an inch and cover with a fine layer of soil. Regardless of where they're sown, keep the soil moderately moist during germination. Once they've reached heights of 5cm, thin so that they're spaced apart by 15-20cm. Make sure to plant out seedlings grown inside when they reach 5-7cm tall.
