Black Adder Agastache Plants produce spikes of smokey red-violet blossoms that flower all summer and into fall. They are a pollinators dream! It offers a long flowering season, heat and drought tolerance, and scented foliage. Removing the spent flowers keeps it blooming longer. Adds eye-popping color and texture. Giant Hyssop grow well in a wide range of well-drained soils, though they are short lived on damp clay.
Companion Planting: Geranium, Monarda, Nepeta

Comment: I ordered the agastache plant along with two other pollinator plants. They arrived in a single box and in good condition.

I'm very pleased with my purchase and plan to buy from GrowJoy ag... More details

Comment: I got this plant specifically for bees whom love it. It arrived very well packaged (in fact GrowJoy could teach other companies how to properly ship plants) and growing. It took well to its transplanting and at the moment is quite green and thriving.
"Fun to grow!"

Comment: I enjoyed watching the Black Adder plant grow. It grows really fast and the plant is interesting before it even blooms. It smells fantastic and the purple isn't as dark as I expected... More of a Lilac color

Comment: My Black Adder arrived healthy and happy. I planted it in the center of a new bed and its flourishing! It's my favorite plant to watch grow. Without blooms it's already making a strong statement! I just ordered two more.
"Beautiful, healthy Agastache plants!"

Comment: I first saw these plants at a place to ride trolleys and knew I had to have them. I found them online at GrowJoy and ordered 3. They came well packaged and fast, a good size and healthy. Beautiful! I planted them quickly and they are doing great. I highly recommend this garden center. Great people, great products!
