Spider flower, spider plant, pink queen
Spider flower is native to Argentina, Paraguay, Uruguay, and southeastern Brazil, and sometimes escapes from gardens to become naturalized in the United States. These striking flowers have been cultivated into many variants.
Plants: Plants are erect annuals, up to 5′ (1.5 m) in height, with round, slightly ridged stems.
Leaves: Arranged in a spiral pattern around the stem. Leaves are palmate—shaped like fingers on a hand—with 5 or 7 leaflets. Each leaflet is narrowly oval, toothed, finely hairy, up to 4½ ⨉ 1½″ (12 ⨉ 4 cm), on petioles (leaf stems) up to 6″ (15 cm) long.
Flowers: In compact racemes at stem tips. Purple, pink, or white, strongly scented, with four petals and six long, graceful stamens. Flowers appear from June to frost.
Fruits: Capsules up to 6 ⨉ ⅛″ (15 cm ⨉ 3 mm).
Habitats: Gardens and occasional garden escapes.
