Inflorescences thyrses or, sometimes, cymes, sometimes solitary flowers, terminal from terminal bud in rosette, 2–200[–1000]-flowered, (some or all flowers replaced by bulbils in S. cernua, S. mertensiana), usually bracteate (ebracteate in S. nathorstii, S. oppositifolia); (bracts leaflike). Flowers [bilaterally symmetric], bisexual (unisexual and plants sometimes gynodioecious, or plants dioecious in S. eschscholtzii); hypanthium free from or 1/4–3/4 adnate to ovary, free from ovary to 0.5 mm, green or pink to purple, (0.1–4 mm); sepals 5, green, sometimes reddish at tips, sometimes ± purple; petals absent or (1–)5, white, cream, yellow, orange, red, pink, or purple, often yellow-, orange-, or red-spotted; nectary disc present or not; stamens 10, (distinct); filaments linear and ± flattened (club-shaped in S. mertensiana); ovary superior to ± inferior, sometimes appearing more superior in fruit, 2-locular, carpels usually (1/4–)1/2 connate proximally or ± distinct; placentation axile (when connate 1/2+ their length) or appearing marginal; styles 2; stigmas 2.
