Many yellow stamens help conceal the nectar secreted in a narrow ring between the filaments and the base of the receptacle. Bumblebees, the principal and most efficient visitors, which can reach sweets more readily than most insects, although numerous others help to self-fertilize the flower, bring to the mature stigmas of a newly opened blossom pollen carried on their undersides from the anthers of a flower a day or two older. When the inner row of anthers shed their pollen, some doubtless falls on the stigmas below them, and so spontaneous self-fertilization may occur. Fruit sets quickly; nevertheless the shrub keeps on flowering nearly all summer. Children often fold the lower leaves, which sometimes measure a foot across, to make drinking-cups. QUEEN-OF-THE-PRAIRIE (Ulmaria rubra; Spirea lobata of Gray) Rose family Flowers - Deep pink, like the peach blossom, fragrant, about 1/3 in. across, clustered in large cymose panicles on a long footstalk. Calyx 5-lobed; 5-clawed, rose-like petals; stamens numerous; pistils 5 to 15, usually 10. Stem: 2 to 8 ft. tall, smooth, grooved, branched. Leaves: Mostly near the ground, large, rarely measuring 3 ft. long, compounded of from 3 to 7 leaflets; end leaflet, of 7 to 9 divisions, much the largest; side leaflets opposite, seated on stem, 3 to 5 lobed or parted; all lobes acute, and edges unequally incised. Prominent kidney-shaped stipules. Preferred Habitat - Moist meadows and prairies. Flowering Season - June-July. Distribution - Western Pennsylvania to Michigan and Iowa, and southward. A stately, beautiful native plant, seen to perfection where it rears bright panicles of bloom above the ranker growth in the low moist meadows of the Ohio Valley. When we find it in the East, it has only recently escaped from man's gardens into Nature's. Butterflies and bees pay grateful homage to this queen. Indeed, butterflies appear to have a special fondness for pink, as bees have for blue flowers. Cattle delight to chew the leaves, which, when crushed, give out a fragrance like sweet birch. WILD ROSES (Rosa) Rose family Just as many members of the lily tribe show a preference for the rule of three in the arrangements of their floral parts, so the wild roses cling to the quinary method of some primitive ancestor, a favorite one also with the buttercup and many of its kin, the geraniums, mallows, and various others. Most of our fruit trees and bushes are near relatives of the rose. Five petals and five sepals, then, we always find on roses in a state of nature; and although the progressive gardener of today has nowhere shown his skill more than in the development of a multitude of petals from stamens in the magnificent roses of fashionable society, the most highly cultivated darling of the greenhouses quickly reverts to the original wild type, setting his work of years at naught, if once it regain its natural liberties through neglect.
