Its main benefit is that it grows quickly and can be harvested several times in a year if planted in early spring. Within this is the corolla the circle of petals, which in turn surround the sexual organs. Consequently, trees gambling on such a risky mode of pollination seem to hedge their bets by producing enormous amounts of pollen ten million grains from one cluster of birch catkins, for example. Cut flowers, particularly those that are pollinated with bees, are frequently used in conjunction with bees, which can be dangerous if you have a bee sting allergy.

This process results in the creation of new plants. This is because they can easily find themselves isolated with no chance of fertilising or being fertilised, so self-pollination is better than no pollination at all. Nectar, a simple sugar solution, is produced by the plant to entice insects to visit flowers. and forget-me-nots (Myosotis spp.) For this reason, wind-pollinated plants may beallergens, but seldom are animal-pollinated plants allergenic.

Humans have always appreciated the fantastic visual display of the showier flowers, and these colours send out an advertisement to passing insects. Many insects, including bees, have discovered ways of stealing nectar from plants without killing them. Stolons, rhizomes, nodes and buds can also be used to reproduce grasses in vegetative propagation. Insect-pollinated trees like birch are difficult to detect with this technique, which favors wind-pollinated trees like those.

These are small containers, fringed with hairs, that enable them to transport pollen back to their nests to feed to their larvae, clearly illustrating how intimately the evolution of flowers and insects are intertwined.

Fruit and seeds are later produced by the fertilized flower. Wind-pollinated flowers do not produce scents or nectar; instead, they tend to have small or no petals and to produce large amounts of lightweight pollen. Attracting animals without the use of petals, color, nectar, or scent is a simple process. Typically, pollen appears in spring as a powdery cloud of fine, yellowish grains. Most grass pollination occurs in May, but specific types of grass pollinate earlier or later than this.
