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

"Love it!"

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!

Comment: I love this plant since it is one (maybe only) Agastache that doesn't reseed and become a pest. It is tall and a beautiful color. I was trouble finding it anywhere and delighted to see that GrowJoy offered it. I ordered 3 and all arrived healthy and good size to grow out.

Comment: I have a couple plants of 'Black Adder' in my flower bed in the front yard and love to see Butterflies sipping nectar from the beautiful and colorful flowers! I ordered two so that the Butterflies and myself will have plenty of flowers to enjoy! Love this Agastache!

Comment: Black Adder Agastache Plants arrived in excellent condition (as fresh as if I had bought them locally). Packing was perfect no damage to boxes or plants. Plants are vigorous, good size, and healthy. I was able to plant them right away; they are doing incredibly well. I will definitely buy from GrowJoy in the future!
