When moths begin their rounds at dusk, the NIGHT-FLOWERING CATCHFLY (S. noctiflora) opens its pinkish or white flowers to emit a fragrance that guides them to a feast prepared for them alone. Day-blooming catchflies have no perfume, nor do they need it; their color and markings are a sufficient guide to the butterflies. Sticky hairs along the stems of this plant ruthlessly destroy, not flies, but ants chiefly, that would pilfer nectar without being able to render the flower any service. Yet the calyx is beautifully veined, as if to tantalize the crawlers by indicating the path to a banquet hail they may never reach. Only a very few flowers, an inch across or less, are clustered at the top of the plant, which blooms from July to September in waste places east of the Mississippi and in Canada. SOAPWORT; BOUNCING BET; HEDGE PINK; BRUISEWORT; OLD MAID'S PINK; FULLER'S HERB (Saponaria officinalis) Pink family Flowers - Pink or whitish, fragrant, about 1 inch broad, loosely clustered at end of stem, also sparingly from axils of upper leaves. Calyx tubular, 5-toothed, about 3/4 in. long; 5 petals, the claws inserted in deep tube. Stamens 10, in 2 sets; 1 pistil with 2 styles. Flowers frequently double. Stem: to 2 ft. high, erect, stout, sparingly branched, leafy. Leaves: Opposite, acutely oval, 2 to 3 in. long, about 1 in. wide, 3 to 5 ribbed. Fruit: An oblong capsule, shorter than calyx, opening at top by 4 short teeth or valves. Preferred Habitat - Roadsides, banks, and waste places. Flowering Season - June-September. Distribution - Generally common. Naturalized from Europe. A stout, buxom, exuberantly healthy lassie among flowers is bouncing Bet, who long ago escaped from gardens whither she was brought from Europe, and ran wild beyond colonial farms to roadsides, along which she has traveled over nearly our entire area. Underground runners and abundant seed soon form thrifty colonies. This plant, to which our grandmothers ascribed healing virtues, makes a cleansing, soap-like lather when its bruised leaves are agitated in water.
