Don't Forget To Add These for Your Plants:

Black Adder Giant Hyssop, also known as Agastache 'Black Adder', is a perennial plant that is known for its striking, dark blue-purple flowers and its attractiveness to pollinators.

This plant typically grows to a height of 2-3 feet with a similar spread. It prefers full sun and is adaptable to a variety of soil conditions, but it thrives best in well-drained, fertile soils. Black Adder Giant Hyssop is also drought-tolerant once established, making it a great choice for xeriscaping or low-water gardens.

The flowers of Black Adder Giant Hyssop are dark blue-purple and appear on tall spikes from midsummer to early fall. The leaves are aromatic and have a minty fragrance when crushed.
