Types Of Plants- A
wide range of plants are
found
in nature, the following are the major
categories of plant types.
Annuals:
are short lived, but are some of the most popular plants
creating bright splashes of colour. They grow from seed, develop
flowers and produce seed for sowing the following year.
Biennials:
are sown one year and flower during the following year.
They
are sown usually during early summer or mid- summer, and subsequently
thinned or transplanted into nursery beds. Then in the autumn they are
planted into their flowering positions.
Herbaceous
Perennials: are popular border plants,that
create vivid
colour every year. During autumn , they die down to soil-level,
surviving the winter in a dormant state and then in the spring the
roots send up fresh shoots. Herbaceous perennials create most of their
new shoots around the outside of the clump, and after a few years the
centre becomes old and woody. When this happens, the whole clump can be
lifted and young pieces from around the outside be replanted.
Bulbs:
for the better part flower in the late winter and spring,
however a few bloom in the summer. Some of the best known flowering
bulbs are daffodils and tulips- the onion is a popular culinary
example. The bulb (botanically speaking), is an underground storage
organ with a bud-like structure and fleshy, scale-like leaves which are
tightly wraped around each other. At times the term bulb, is loosely
used to describe other energy-storing underground organs such as
tubers, corms, and rhizomes. Tubers are swollen stems or roots,dahlias
are root tubers, while potatoes are stem types. Corms, such as crocuses
and gladioli have greatly enlarged stem bases and rizomes are
eitherthick and partially buried or slender and totally underground.
Alpines:
in nature, grow in alpine regions where they thrive above
the
tree-line but below the permanent frost-line. However in garden terms,
it means any plant grown in a rock garden. True alpines are very hardy
and survive low temperatures, but garden alpines are soon damaged by
cold and water. Conifers:
can mature to over 30m (100ft) high, while others reveal a
ground-hugging habit. Most conifers are evergreen but a few, such as
the maidenhair tree(Ginkgo biloba), are deciduous and bear a fresh
array of leaves each spring. Conifers usually bear their seeds in
cones. Shrubs:
persist from year to year,creating a permanent feature in
the
garden. Shrubs which differ dramatically from trees, have
many stems arising from below or level the soils surface.
Trees: are
distinguished from shrubs by having a single, woody
strem(trunk) that grows from soil level to where the branches
arise.They are also woody structures like the shrubs, some living for
hundreds of years.
