English plurals. English nouns are inflected for grammatical number, meaning that if they are of the countable type, they generally have different forms for singular and plural.
Growing Daylilies. We'd describe the Daylily as the backbone of the perennial garden except that would do a disservice to this most durable plant -- backbones, as every gardener knows, are fragile things, whereas Daylilies are close to indestructible.
Poppy. Papaver_ spp. Poppies' papery, almost artificial-looking flowers are well-loved, and there are a surprising number of different kinds. The finer species including Iceland, Alpine, and Atlantic poppies have a special charm with flowers in myriad colors in spring. Oriental poppies are bristly and less refined, but they have huge, exploding flowers of brilliant reds, pinks, white, oranges, and plum, some with double flowers in summer. Most are blotched with black at the base and centered with a boss of black stamens.
