Yellow Giant Hyssop grows quickly to reach heights of 3 to 8 feet. The bigger, lower leaves can grow to be as huge as a thick piece of bread. And, depending on the plant’s age and general height, its bloom spike can be up to 16 inches long! The creamy tiny blooms that gather together on the spike are the only thing petite about this plant. In late summer, the blooms open one at a time, changing the colour to a delicate, mellow yellow.

In addition, Yellow Giant Hyssop blooms are a thriving nectar supply, attracting and supporting bumblebees, sweat bees, and butterflies throughout the fall season and, in some cases, right up until the first frost. According to research, this is one of Ontario’s top 20 plants for feeding pollinating insects.
