Classifying Plants
Early classification was based upon segregating those plants that were harmful from those that were not.
They were further divided by their specific uses
Plants that were eaten, used for medicine or were poisonous. Slide3
Classifying Plants
Some plants are classified by their life cycles
Annual (winter and summer)
Germination, Growth, Flowering, Death
Perennial
Germination, Growth, Flowering, Dormancy and the cycle starts over
Biennial
Season 1-Germination, Growth, Dormancy, Growth (season 2) Flowering, DeathSlide4
Plant Classification
Some are classified by stem type.
Herbaceous Plants-Stems that are soft and not woody, such as herbs, certain vines and turf grasses that die back to the ground each year.
Woody Plants-Includes any shrubs, trees or certain vines which produce wood and have buds surviving above ground over the winter
Deciduous Plants-leafless during a portion of the year (usually winter).
Evergreen Plants-keep their leaves year round. They are either narrow leaf or broadleaf. Slide5
Plant Classification
The ability of a plant to withstand colder temperatures is known as hardiness.
A tender plant is more sensitive to temperature extremes
A hardy plant is less sensitive to temperature extremes

Plant Classification
Dicots
are plants characterized by two cotyledons (seed leaves) in their seedling stage. They have flower parts in fours or fives or multiples of these numbers
Monocots are plants characterized by one cotyledon in their seedling stage. They have flower parts in threes or multiples of 3.Slide7
Scientific Classification and Names
No two plants have the same scientific name
The scientific name helps the scientists and horticulturists identify plants
and recognize
