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 ...
They are modified for flower color, fragrance, flower shape and plant architecture. [8] The first genetically modified ornamentals commercialised altered colour. [ 9 ] Carnations were released in 1997, with the most popular genetically modified organism, a blue rose (actually lavender or mauve) created in 2004. [ 10 ]
Atropa bella-donna flower. Atropa bella-donna is a branching herbaceous perennial rhizomatous hemicryptophyte, often growing as a subshrub from a fleshy rootstock. Plants can reach a height of 2 m (7 ft) (more commonly 1.5 m (5 ft)), and have ovate leaves up to 18 cm (7 in) long.
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.
The outer stems of the plant bend into circular rings after a relatively short period without water. The inner stems instead curl slowly into spirals in response to desiccation, due to the action of the strain gradient along their length. [3] Selaginella lepidophylla reaches a maximum height of 5 cm, and is native to the Chihuahuan Desert. [5]
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 ...

Wilkesia gymnoxiphium is a monocarpic rosette shrub, with rosettes elevated on woody stems as much as 5 m (16 ft) tall.Distinctive features include a usually unbranched, monocarpic axis, leaves in whorls of 9–15 that join to form a basal sheath around the stem, and peduncles that are commonly branched.
