Enkianthus fall foliage
Redvein Enkianthus is about to betray its quiet charms any day now, with a display of technicolor fall foliage in shades of gold, orange, fiery red through purple. In mid to late spring it delights in a more soft-spoken way, bearing dainty clusters of white or red bells, depending on the cultivar. E. ‘Lipstick’ has white bells delicately edged in brick red, ‘Red Bells’ are colored, as the name suggests, coral red, and ‘Showy Lantern’. A slow growing shrub at first, it is often listed at growing from 6-8′ tall and 4-5′ wide, but with age it can easily reach 15′ or more with a wider reach. In fact, Enkianthus campanulatus can be pruned to from a lovely small tree. It is a perfect candidate for the partially shaded garden, both large and small.

Grow Redvein Enkianthus in full sun or partial shade. It enjoys an enriched, well drained, acidic soil that stays evenly moist, although we have found it to be quite forgiving of dry spells, once established. It is deer resistant, but please note that deer will eat almost anything if hungry enough. Perfectly hardy in zones 5-8, with some reporting success growing it in zone 4B.
Waxbells, as Kirengeshoma palmata is commonly called, is an herbaceous perennial with a shrublike habit that adds striking foliage and sweet pale yellow flowers to the late summer shade garden. The flowering display begins in mid August and continues through September. Earlier in the season, the large maple like leaves add bold contrast to the many delicate textures that predominate in our beds. Kirengeshoma may be a little late to break dormancy in the spring, since the new shoots are quite frost sensitive, but once it finally feels the weather is safe, it quickly grows to a height of 4-5′. With time, plants form large clumps 3-6′ across. And if you need another big plus, the deer dislike it.
Kirengeshoma is native to the woodlands and low mountain regions of Japan and Korea, which accounts for its hardiness through zone 5. It grows best in a rich, slightly acidic soil that is moist yet well drained. Propagate by seed or by division in early spring. We like to associate Kirengeshoma with blue and gold Hosta, such as ‘Deep Blue Sea’ and ‘Brother Stephan’ as well as late blooming Actaea ‘Hillside Black Beauty’ .
