This magnificent hardy perennial, although it sells well with nurserymen, has not yet become so popular as it deserves to be in the market. There are several varieties, some being comparatively poor and worthless from a selling point of view. The varieties known as splendens and grandiflora are the only ones worth growing for cut flowers, as they have very long stems and numerous crimson-scarlet bell-shaped flowers which last a long time. The Heucheras should be grown in rich, gritty, well-drained soil, in warm sunny spots, and may be increased by division in early autumn. This is the only way to keep a fine variety pure. Seedlings are easily raised, but there are likely to be many miserable forms amongst them. There are several other species.
