Like Clematis: An alpine like clematis (like clematis alpina) now climbs up the rock face on a diagonal; a perfect clump of broom (Cytisus x praecox 'Luteus') flows over the edge at the far right of the semicircle; and some smaller Japanese hosta (Hosta Nakaiana) grows along the outside base, shel¬tered from the afternoon sun.

In the space of a few months they grow, flower and die, leaving the ground free for further cultivation, if necessary, and for other plants. Biennials are plants which must be renewed annually from seed, since they die after they have flowered and set seed. In this they resemble annuals, but biennials take over a year to complete their cycle of growth. Seed sown one year will produce plants that will flower the next year, ripen their seed, and die before the second winter.
MANY BIENNIALS flower in early and mid¬summer, thus usefully filling an awkward gap that can occur between the spring and summer flowers. Like annuals, they are temporary plants which should be pulled up and put on the compost pile when they have finished flowering. Also, as with annuals, though it's easy enough to save seed of most kinds it is usually impossible to prevent cross-fertilization of different varieties, as a result of which home-saved seed produces only a mongrel population. The distinction between annuals, biennials and herbaceous perennials is not always clear-cut since sometimes varieties of one group can be treated as if they belonged to one of the other groups; hollyhocks (Alcea), for example, can be grown as annuals, biennials or short-lived perennials. However, to be sure of a regular succession of biennials it is necessary to sow seed every year at the correct season.
On The Other Hand See Biennials Are Plants:Plants are called annuals, biennials are plants or per-nnials, according to the length of time the root jves, but the differences are not always absolute, .rid are often changed by cultivation. Perennials, >uch as quack grass and peony, often have thick¬ened, tuberlike roots, in which nourishment is stored during the growing periods, to be drawn upon when the plant flowers. biennials are plants such as beets and carrots show similar development.

Climate, more than any other factor, determines the success or failure of the gardener. A garden requires adequate sunshine and rainfall if plants are to thrive in it, but it also needs protection against extremes of weather.
