longflower alumroot Interesting Notes

A beautiful display when used en masse, the long flowering stems of Heuchera longiflora sway high above deep green foliage mottled in silver highlights. Tubular calyces surround the pale pink flowers and securely affix them to upright stems. Expect flowering from late May into June with plant topping to 10” in height, but up to 30” in flower, and 20” in width.


H. longiflora is commonly found in shaded woods and roadcuts over limestone substrates and outcroppings from southern Ohio to Alabama. While these might be its preferred habitat, H. longiflora is rare in the wild. Similar to H. americana, longflower alumroot differentiates itself by its larger flower bloom.


Tolerant of alkaline soils and dry shade, H. longiflora is an excellent addition to a woodland garden and lovely planted in massed sweeps, interplaying with spring Phlox, Hellebore, and ferns. While found to be the one of the most sun tolerant of native Heuchera in Mt. Cuba’s Heuchera trial, longflower alumroot benefits from consistent moisture in bright areas. Disease resistant and care-free, this Heuchera has been known to have some red venation develop in the cooler months, off setting its silver-streaked foliage.
