Deep black-purple, single flowers are produced on tall, sturdy stalks in midsummer.
Other than their fabulous blossoms, one of the best traits about this series is that the plants are truly perennial, not biennial.
Feel free to grow hollyhocks under Black Walnut trees; they are tolerant of the toxic juglone that is emitted through the trees’ roots.
