Hemerocallis flava is the lemon Day Lily which blooms profusely in June and should be planted in clumps at the corners of the beds or the foot of a flight of steps. Hemerocallis fulva is the orange Day Lily, a rampant grower, with larger and less attractive flowers than flava. Plant it in the large beds, two or four clumps balancing each other; its bloom is borne on long stems well above the other plants. It spreads very rapidly and should be kept from reaching out into the clumps of Phlox, Foxglove, etc., for a little of it goes a long way.
