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.
It thrives in hot, humid weather but not extended periods of direct sunlight. If the plant withers due to lack of water, it tends to recover quickly after rain or watering. Although rare, the seed-producing flowers are very fragrant and blossom in late autumn. The tiny seeds may be harvested for planting, but they are very delicate and easily ...
[4] [5] Dictamnus is tap-rooted, making mature plants difficult to establish and resistant to division; young plants often need three years before they begin to flower, and since it is late to break into leaf in spring, even quite mature clumps may be harmed with vigorous soil-working in spring.
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 ...
Hydrangea flowers, when cut, dehydrate easily and wilt very quickly due to the large surface area of the petals. A wilted hydrangea may have its hydration restored by first having its stem immersed in boiling water; as the petals of the hydrangea can also absorb water, the petals may then be immersed, in room-temperature water, to restore the ...
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 ...

The uniform alignment of the flowers does result from heliotropism in an earlier development stage, the bud stage, before the appearance of flower heads. The apical bud of the plant will track the Sun during the day from east to west, and then will quickly move west to east overnight as a result of the plant's circadian clock. [11]
