Introduction<\/h2>\n

Across southern Africa, and on windowsills worldwide, Crassula<\/em> plants manage a neat trick: compact bodies that conserve water, and flower displays that look delicate but hold up in dry air. When people think of the group, they picture the jade plant, yet the genus runs from coin-leaved shrubs to tiny, cliff-hugging mats. In most species, the flowers are small, starry, and massed\u2014pretty up close, and persuasive to bees, flies, and small wasps. Just as important, they are not always five-parted<\/strong>; many Crassula<\/em> are 5-merous, while plenty are 4-merous<\/strong>.<\/p>\n

The Details<\/h2>\n

In broad outline, Crassula<\/em> flowers follow a repeating plan: sepals, petals, stamens, nectar scales, and free carpels. In many species, the count is five sepals, five petals, ten stamens, five nectar scales, and five carpels<\/strong>. In others, the count drops neatly to fours and eights<\/strong>\u2014four sepals, four petals, eight stamens, four nectar scales, and four carpels<\/strong>. The ovary is superior, sitting above the point where other parts attach, and the carpels mature into many-seeded follicles. As a quick rule, the number of stamens is usually twice<\/strong> the number of petals.<\/p>\n

In the field, or on a bench, petal posture and color tell you plenty. White and cream dominate, often flushing pink with age or cold nights. On jade plants, cool, bright winters trigger clouds of white stars with a light, honeyed scent. On cliff species, tight sprays open in succession, handing off pollen quickly before heat or wind shuts the show down. When drought stretches, plants hold back; after a good pulse of moisture, they stage fast, synchronized blooms that pull in everything with a tongue.<\/p>\n
