Mimosa pudica (also called sensitive plant, sleepy plant, [citation needed] action plant, humble plant, touch-me-not, touch-and-die, or shameplant) [3] [2] is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop ...
Both male and female flowers grow in the same inflorescence. The female flowers open first, and the male flowers open a day or two later. That usually prevents the flower from self-pollinating. After the flower dies back, a single leaf, which resembles a small tree and reaches a similar size, grows from the underground tuber. The leaf grows on ...
Flowers grow 8.6–12.4 cm (3.4–4.9 in) long, and are open for less than 24 hours. Since they form only at the top of the plant and the tips of branches, saguaros growing numerous branches is reproductively advantageous. Flowers open sequentially, with plants averaging four flowers open per day over a bloom period lasting a month. [7]
Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
They can be 10–20 centimetres (3.9–7.9 in) long and 15 centimetres (5.9 in) wide. The leaves are coppery green with red splashes, giving them a mottled appearance. Separate male and female flowers appear on the same plant. The male flowers are in long spikes which hang downwards while the female flowers are in short spikes.
The dogwood bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the white mulberry tree, with flower movement taking 25 microseconds, as pollen is catapulted from the stamens at velocities in excess of half the speed of sound—near the theoretical physical limits for movements in ...
Several flowers, hundreds of which comprise the inflorescence. It produces a stemless cluster of long, rigid leaves which end in a sharp point. The leaves are 20–90 centimetres (8– 35 + 1 ⁄ 2 inches), [5] rarely to 125 cm (49 in), long and 0.7–2 cm (1 ⁄ 4 – 3 ⁄ 4 in) wide, and gray-green in color. The leaf edges are finely saw ...
Each inflorescence is a ball-like structure covered by 40 to 100 small flowers that have five tiny petals (pentamerous) and long erect stamens, which give the flower head a fluffy appearance. [4] Developing after flowering has finished, the seed pods are flattish, straight or slightly curved, 5–14 cm (2–6 in) long and 5–8 mm wide.
