There are three main types of annual flowers, hardy, half-hardy and tender.

一年生的花主要有三种：耐寒型的，半耐寒型的和不耐寒型的。

An annual is best known as a plant that completes it's life cycle in a single season. Hardy annuals can survive cold temperatures and some light frost, while tender annuals cannot tolerate cold temperatures and should be planted only after there is no more danger of frost. Half-hardy annuals can tolerate some cold temperatures, but are usually killed by frost. Annuals make excellent space fillers for the perennial garden.

一年生植物最显著的一个特点就是它在一个季节内完成它的生命轮回，耐寒的一年生植物能够在低温和轻微霜冻的条件下生存，但是幼嫩的一年生植物不能忍受低温，他们只能在没有霜冻危险的条件下种植，半耐寒型一年生植物能够经受一些低温条件的考验，但是通常他们因为霜冻死亡，一年生植物能够为多年一成不变的庭院创造一个很出色的空间。

The structures of the two-year-old tap roots are similar to that of the one-year-old ones, while the periderm thickness is increased. In the secondary xylems of the two-year-old roots, the woody fibers are distributed in groups and the interxylary phellem appears. The vascular rays are multiseriate. Phellem cells surround a sclereid form the phellem cycle in the phloem nearby the periderm.
