For over three decades, Acorus gramineus 'Ogon' has been a landscape staple in the gardens here at Juniper Level. Acorus gramineus 'Ogon' is a 1975 Barry Yinger introduction from Japan...a glaringly beautiful, evergreen perennial with brilliant yellow, deer-resistant foliage, brightest from fall through spring. While the overall effect is bright yellow, Acorus gramineus 'Ogon' actually has a vertical green stripe down the side of each 1/8" wide plasticized leaf. Acorus gramineus 'Ogon' is very easy to grow, forming a fabulous 1' tall slowly-widening in moist shade. It's roots have antifungal and antibacterial properties.


Because Acorus 'Ogon' is evergreen, it does not require an annual pruning. However, if the foliage looks tattered due to hail or other damage, it can be cut to the ground and will resprout quickly.

Growing Conditions:

Acorus gramineus 'Aureus' is best in moist soil, although it is quite tolerant of short periods of drought. Light open shade or early morning sun is best. The foliage can burn in full sun, and growth slows dramatically in dense shade.

The visual impact of Acorus gramineus 'Ogon' in the winter garden is quite striking, when many other woodland perennials are still dormant.
