Annuals The plants whose life cycle
usually lasts for only one year. Their life cycle begins with the germination
of the seed. The plant then blooms, producing the next generation of seed, after
which the parent plant dies. Hardy Annuals These are
frost hardy and can be sown directly outdoors in spring. Those plants that
survive through the winter and produce new growth the following spring are not
considered to be annual plants. Biennials They are
somewhat more trouble for the gardener, since they keep growing during their first
year and do not bloom until the second. Their great advantage is that their seeding
stage produces new plants which will bloom again two years later, making it unnecessary
to plant additional seeds. . E.g. Foxgloves |
Herbaceous Perennials
A plant in which the root lives three or more years and the aboveground parts
die back to the root each winter .Perennials Describes
herbaceous plants that persist for more than two years, dying back each year to
the same rootstock. Lillies, phlox, hostas, and yarrow are all perennials. Some
plants are perennials, but will die if overwintered in northern climates; these
are tender. Those that can take cold winters
are considered hardy. Trees A
woody plant that usually has one main stem and reaches a height of at least 12
ft. Shrubs Woody plants
that grow close to the ground and have several stems beginning at its base Small,
low shrubs such as lavender, periwinkle and thyme are often termed subshrubs.
