Ajuga incisa 'Bikun'

Giant Bugle

Plant Type:


Ajuga incisa 'Bikun' ('Frosted Jade') - This unusual species of Ajuga displays incised leaves of medium green are broadly and irregularly edged in creamy yellow. The spring flowers are a deep, rich beautiful shade of purple-blue and no doubt as attractive to hummingbirds as its more common and colonizing cousin Bugleweed, Ajuga reptans. The bees certainly appreciate it. Unlike its rampant cousin the Giant Bugle is a clumping perennial and completely deciduous. Site 'Bikun' in part sun, dappled to open shade in fertile, moist soil. 'Bikun' is probably going to be a doer in USDA zone 5b where sheltered and mulched. If ordered in autumn your Ajuga will arrive cut back prepared for the long winter's nap. Established pot grown perennial from division.

It is imperative that gardeners understand their USDA planting zones. If you are purchasing a plant or plants in the autumn shipping window it is your responsibility to know whether or not the plant is appropriate for fall planting in your zone. Generally we caution that plants at the northern end of their climate range are best considered for spring planting so they have a chance to settle in and grab hold to their new environs. If you purchase a tricky plant now and it perishes in the winter please understand that we will not take responsibility. If you are uncertain be prudent, wait until spring.
