Contrast blue with yellow. ‘Blue Heaven’ stands out when paired with Forsythia ‘Gold Leaf’.
Designers and collectors are also attracted to hostas with unusual growth habits. ‘Krossa Regal’ was the first— and is still the best—of the vaseshaped hostas, thanks to its ancestor, H. nigrescens, the only vase-shaped species. ‘Krossa Regal’ makes a great accent plant with its smooth and cupped blue leaves. ‘Salute’ also has a vaselike habit, but on a much smaller scale, with twisted blue leaves that grow upright instead of lying flat.
‘Elvis Lives’ was the first hosta to combine the arched habit of the Japanese rock hosta (H. kikutii) with blue-colored leaves. H. kikutii was also used to produce ‘Hillbilly Blues’, the first flat-spreading blue-leaved hosta. It measures 3 to 4 feet wide by 10 inches tall and has the deeply impressed, textural leaf veining prevalent in H. kikutii.
Detail-oriented gardeners, or those with small spaces, truly appreciate the appeal of small hostas. ‘Popo’ and ‘Baby Bunting’ are the bluest of the miniatures. These tiny selections sport leaves that are bluish-green on delightfully compact mounds.
