Defining concepts – plants.
Gardeners use a lot of more or less specialized terms, to describe plants, their growth and development. So if we are just starting our adventure with gardening, some of them are worth knowing.
Annual plants it's plants, which have their entire life cycle – from germination from seed to seed production – przechodzą w ciągu jednego okresu wegetacyjnego, and then they die. This cycle does not exceed a year or so. The height of annual plants comes to 60 cm (or more, if they are e.g.. sunflowers), usually less. Some gardeners mistakenly call ornamental species annuals that are grown for only one year, which later only lose their attractive appearance. Annual plants are often used to fill empty spaces in flower beds.
Biennial plants they need two growing seasons to complete their development cycle. Some biennials can be grown as winter crops, sown in late summer or fall. They produce flower shoots and seeds the following year. Biennial plants add height to flower beds. A typical example, often found in gardens, there is foxglove. Some perennials are considered by gardeners as biennials, because after two years they produce fewer flowers and are no longer as attractive. A lot of biennial plants can be found in vegetable gardens, e.g.. onions or carrots, although they rarely bloom and produce seeds in the second year, Which is why, that when they have already stored the right amount of reserve substances, let's eat them.
Perennial plants it's plants, who live for more than a year or two. They include both trees, as well as herbs – plants with non-lignified aerial parts. It's worth pointing out, that some perennials, e.g.. tropical, due to the high sensitivity to frosts in our climate zone, are treated like annuals. Most perennials take a long time, before it blooms. For smaller plants, this period is two to five years, and for trees and shrubs from three to 30, where it is the rule, that larger plants take longer than smaller ones. The trees will therefore bloom later than the shrubs. In most perennials, it is a good idea to remove dead flowers, thus prolonging their flowering period.
Herbaceous plants are plants with a non-lignified stem, which can belong to both annuals, two-year-olds, as well as herbs. Their growing season usually ends with the onset of frost (although there are exceptions, e.g.. waiters). Most often, interesting compositions are created on flower beds from herbaceous plants. They grow more in breadth than upwards from year to year, therefore they are more convenient to grow than shrubs and trees.
Evergreen plants, unlike shrubs and trees that shed their leaves in winter, which we are wonderful before, autumn coloration, they do not lose their leaves, nor do they die for the winter like herbaceous plants. Evergreen plants are especially valuable in winter, providing a cover and caring for color in the garden, and often flowers and fragrance. Most of them are coniferous or thick, leathery leaves, like for example. boxwood. Species are also included in evergreen plants, which retain gray or silver leaves all year round. Much comes from the Mediterranean basin, although there are also popular herbs among them, e.g.. lavender, thyme or sage. All of them require a sunny position and a well-drained substrate.
