Definitions
• Botany is the science or study of plants• Horticulture is the science and art of
cultivating flowers, fruits, vegetables, grass, and ornamental plants in an orchard, garden, nursery or greenhouse.
• From the Latin: Hortus (garden) and cultus (tilling)

Classifying Plants
• Classification by:1. Use2. Temperate Requirement3. Ecological Adaptation4. Taxonomy5. Stem and leaf structure6. Life Cycle

Classification by Use
• EDIBLE – Fruits

Classification by Temperate Requirement
• Tropical plants vs. Temperate-zone plants• Warm vs. Cool season plants• Tender vs. Hardy plants• Long day vs. Short day plants• Cold hardiness zone plants

Classification by Ecological Adaptation
• Alpine• Prairie• Ponderosa pine forest• Pinyon/Juniper forest• Riparian• Xeric (dry)

Classification by Taxonomy
• Plant Kingdom divided into two groups:– Non-vascular plants– Vascular plants
• Nearly all plants in the garden are vascular
![Page 8: Garden Botany](https://reader035.fdocuments.us/reader035/viewer/2022062305/5681691a550346895de038f3/html5/thumbnails/8.jpg)
Classification by Taxonomy
• Gymnosperms– Do not have true flowers– Seeds are enclosed in
fruits– Most seeds are
produced in cones

Classification by Taxonomy
• Angiosperms– Produce flowers– Develop fruits that
contain seeds– Can be divided into
monocots and dicots

Plant Evolution

Classification by Stem and Leaf Texture
• Herbaceous plants• Woody plants• Deciduous plants• Evergreen plants• Broadleaf• Narrowleaf• Grass-like
Bee Balm, Herbaceous/non-woody stemsButterfly Bush, Woody stems
Deciduous plants shed their leaves every yearEvergreen plants hold their leaves year-round
Corn is a good example of broadleaf
Narrow leaf lavendar

Classification by Life Cycle
• Annuals• Biennials• Perennials
![Page 14: Garden Botany](https://reader035.fdocuments.us/reader035/viewer/2022062305/5681691a550346895de038f3/html5/thumbnails/14.jpg)
PLANT PARTS
• Roots• Stems• Leaves• Fruits• Flowers• Seeds
![Page 15: Garden Botany](https://reader035.fdocuments.us/reader035/viewer/2022062305/5681691a550346895de038f3/html5/thumbnails/15.jpg)
Roots• Absorb water and
nutrients from soil• Anchor the plant• Provide support for stem• Store sugars and starches
(needed for photosynthesis)
• Source of winter survival for perennials
• Fibrous roots vs. Tap roots
![Page 16: Garden Botany](https://reader035.fdocuments.us/reader035/viewer/2022062305/5681691a550346895de038f3/html5/thumbnails/16.jpg)
Stems• Connects roots to leaves• Supports buds and leaves• Phloem and xylem serve as
channels in the stem for carrying water, minerals, and sugars to other plant parts. Xylem brings water up the stem, and Phloem sends water down.
• Stems grow above or below the ground.

Leaves
• Absorb sunlight energy to make food through the process of photosynthesis
• Take up carbon dioxide and release oxygen
• Store energy• Control water through
transpiration• Simple or compound
Photosynthesiswater + CO2 sugar + O2

Flowers
• Showiest part of plants; fragrant and/or colorful to attract pollinators
• Important for sexual reproduction
• Self pollinating or cross pollinating
![Page 19: Garden Botany](https://reader035.fdocuments.us/reader035/viewer/2022062305/5681691a550346895de038f3/html5/thumbnails/19.jpg)
Fruit
• Part of the plant that surrounds one or more seeds
• Spread seeds• Attracts animals to help
spread seeds

Seeds
• Contain the information needed for a new plant to grow
• Embryo• Endosperm• Seed coat
