PPA names Hakonechloa macra 'Aureola' as Plant of the Year

Perennial Plant Association named Hakonechloa macra ‘Aureola’ (golden Japanese forest grass) as its 2009 Perennial Plant of the Year.

This clump-forming deciduous grass produces arching, linear leaves that are bright yellow with narrow, longitudinal lime-green stripes. If grown in partial shade, yellow tones in the foliage will be most pronounced. In deep shade, variegation will be lime-green.

In fall, the leaves often develop a reddish tinge. In milder climates, the grass will remain throughout winter. In colder areas, it’ll dieback to the ground.

The grass spreads by stolons, but isn’t invasive. Walters Gardens has it listed as “a slow grower and will not rapidly overtake its neighbors.” Plants reach 12-18 inches tall and 18-36 inches wide.

It is hardy in USDA Hardiness Zones 5-9.

Geranium ‘Rozanne’ is the 2008 Perennial Plant of the Year.
