Hypericum kalmianum ‘Ames’
Blooming Time
Exposure
With a uniform shape and fine texture, this shrubby perennial has earned its way into the sunny landscape. Its features include blue-green slender leaves that are borne on dense, upright branches and masses of charming golden yellow flowers in midsummer. It is particularly useful where irrigation is limited, tolerating dry conditions and holding up well through the Midwestern heat and humidity. Its strong root system and dense globose habit make it useful for controlling erosion or for general ground covering in any type of soil, and it requires very little maintenance.

A spring application of a 3-1-2 ratio (such as a 15-5-10) can be applied at a rate of about 10 pounds per 1000 square feet, and during early fall, an application of a 2-1-2 ratio (such as a 10-5-10) can be applied to encourage root development and cold hardiness.
