Why do gardeners like Stella d'Oro daylily so much? Well, for one thing, it stays relatively short. This is not the case with many other daylilies, which are tall and flop over in the face of high winds, unless they are properly staked. Stella d'Oro does not require staking.
Stella d'Oro daylily also blooms earlier than many other daylilies, is a long-blooming perennial and is capable of reblooming. Another fact that accounts for its popularity is that it's not fussy about the conditions in which it grows.
Add fragrance and the good looks of its buttery-golden blossoms to the equation, and it's not hard to figure out why so many gardeners grow Stella d'Oro.
Notice that, throughout this description, I have referred to these plants as "daylilies," not as simply "lilies." The two names are not, in fact, synonymous. A true lily belongs to the genus, Lilium. Daylilies, meanwhile, belong to a different genus: Hemerocallis.
"Why is this distinction important?" perhaps you ask. The answer, in part, is reflected in the common name, "daylily." A daylily flower lasts only one day; the flower of a true lily lasts longer. So if you wonder why the individual flowers of your Stella d'Oro die so quickly, take comfort in the fact that you're not doing anything wrong: this attribute is in the plant's genes.
