Gardeners' Notes:

Neutral catrose On Jun 20, 2013, catrose from Applewood, CO wrote:

The label on my newly aquired Big Bazooka Hyssop is substantially different than noted here.

I just purchased this plant from Timberline Gardens in Wheat Ridge, CO. I was told by a specialist there, who breeds Agastaches, assured me that the label of this plant is correct for Colorado's growing conditions. They are as such:

48" high x 36" wide, full sun. Zone 5.

I'll be growing in Zone 5 at 5800 feet in at least 7 hours of sun, well-drained soil with at least 10 percent organic matter. That's the best we can hope for here. I'll let you know if the height and width end up different than the label.


This plant has been said to grow in the following regions:

Brighton, Colorado
Stanhope, New Jersey
Xenia, Ohio
Hanover, Pennsylvania
San Antonio, Texas
