Pedunculate (stalked) pale pink or purple flower heads arise from the leaf axils in mid-summer with more and more flowers as the plant gets older. A single flower survives for less than a day, and usually dies completely by the next day. Flowers of M. pudica are very brittle and soft.
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 displays a soft green colour with very fine leaves. Not suited to plant close to buildings, [2] nor to park underneath, due to a very fine powder which can cause staining. Excellent as a tree to lure birds and insects, as well as providing beautiful shade. Wind and weather resistant, can deal with too much water as well as droughts.
It is a diaspore that, once mature and dry, detaches from its root or stem and rolls due to the force of the wind. In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. [1]
The plant becomes woody as the fruits develop. As they ripen, the plant begins to die, dries out and becomes brittle. In that state the base of the stem breaks off easily, particularly in a high wind. The plant then rolls readily before the wind and disperses its seeds as a tumbleweed.

Dissolved salts become concentrated in the plant tissues as water evaporates. The trehalose produced by the plant acts in place of the evaporating water, so preventing the salts from causing damage and protecting against death due to an excess of salinity. S. lepidophylla also uses betaines, substances which have the same function as trehalose. [8]
A spike, usually pendulous, in which the mostly small flower s are unisexual and without a conspicuous perianth, e.g. in willows, poplars, oaks, and casuarinas. The individual flowers often have scaly bract s and are generally wind-pollinated. Catkins are usually shed as a unit. caudate Having a narrow, tail-like appendage or tip, e.g. a drip tip.
The papyrus plant is relatively easy to grow from seed, though in Egypt, it is more common to split the rootstock, [10] and grows quite fast once established. Extremely moist soil or roots sunken in the water is preferred and the plant can flower all year long. [11] Vegetative propagation is the suggested process of creating new plants.
