Heuchera longiflora

Also known as:

longflower alumroot


maple leaf alumroot


long flowered alumroot

Scientific Synonyms:

Heuchera aceroides, Heuchera longiflora var. aceroides, Heuchera scabra


Heuchera longiflora is very similar to H. americana, but is much less common and can even be considered rare. The most distinguishing feature is the production of larger flowers. They are yellowish in color, and are borne high above the foliage on stems that can grow 2' tall or more. The plants form basal clumps up to 10" tall, with maple-shaped leaves with conspicuous silver markings. As cold weather sets in, the foliage will shift to reddish and purplish hues.


Longflower alumroot can be quite spectacular when planted in large groups. It will create an impressive ground cover with its silver mottled foliage contrasting wonderfully against other shade-loving plants. It prefers rich soil that is moist and well-drained, but is really quite adaptable, and will even tolerate poor, rocky soil. It is best planted in light open shade or filtered light but will also tolerate full shade, and part-sun if the soil is kept consistently moist. The blooming period begins in late spring and lasts about a month. Zones 5-8


Can be propagated from seed, but they are tiny and difficult to collect. Can be propagated by crown division in early spring as the leaves begin to emerge, or fall once the plant has gone dormant.
