Alcea rosea 'Nigra'
Hollyhock (Alcea rosea 'Nigra') is truly an amazing plant species. It boasts stunning deep purple, velvety flowers with intricate yellow stamens that add visual interest to any garden. Longer-lasting than many other perennial plants, this species of hollyhock blooms from summer through to fall and is an excellent source of nectar for pollinators. The deep purple hue is a striking addition to any outdoor space, and its hardiness makes it easy to propagate and grow. Its upright habit and resistance to rabbits and deer make it the ideal choice for both private and public gardens. Whether you’re a novice gardener or a seasoned expert, there is nothing quite like the majestic beauty of hollyhock 'Nigra.'

watering
When watering hollyhocks, wait to water until the top inch of soil is dry. This could mean watering only once a week or even less, depending on the climate. As hollyhocks are a shallow-rooted perennial, water deeply and evenly 1 or 2 times a week. If the plant is in full sun, water more frequently than if it is in shade. Aim to keep the soil slightly moist, but do not saturate it. As a general guide, provide 1 to 3 inches of water per week.
sunlight
Hollyhock (Alcea rosea 'Nigra') needs full sun for the best growth and flowering. During the hottest part of the day the plant should be in a spot that is sheltered from the direct sun to prevent scorching. At least 6 hours of direct sunlight each day is needed to promote healthy flowering. The ideal time for growth is in the morning and late afternoon, when the sun’s rays are more gentle. During the hottest part of the day, light shade for Hollyhock is beneficial.
pruning
When pruning hollyhocks, it's best to remove the oldest and tallest stems first. This encourages lateral branches, which results in a more full and bushy plant. Once the older stems are removed, you can then lightly prune the lateral branches and flower stalks to improve the overall shape of the plant. For plants growing in containers, prune more selectively, leaving at least 2 sets of leaves on each stem; this helps encourage flower production. Also, remove any dead, diseased or damaged branches. In general, it's best to only prune hollyhocks if needed to improve their overall shape and to remove any dead or damaged branches. Heavy pruning should be avoided as this may reduce the numbers of flowers produced.
