Flowers in the Landscape Unit 7 B: Flowers in the Landscape
Objectives Define the terms. Differentiate among annual, perennial, & biennial flowers & list examples of each. List the characteristics of hardy & tender bulbs. Explain the difference between flower borders & flower beds.
1. Define the Terms Direct seeding: placement of seeds in the ground. Bedding plants: herbaceous plant preseeded & growing in a peat pot or packet container. Dormant: period of rest for a plant. Bulbs: flowering perennial which survives the winter as a dormant fleshy storage structure.
2. Differentiate Among Annuals, Perennials & Biennials - Flower that completes it life cycle in one year. - Goes from seed to blossom in a single growing season & dies as winter approaches. - Most commonly used in summer landscapes.
2. Annuals (cont.) Bloom throughout the months of June, July, August & September. Examples: petunia, marigold, salvia & zinnia.
2. Examples of Annuals Petunias
2. Examples of Annuals Marigolds
2. Examples of Annuals Salvia
2. Examples of Annuals Zinnia
2. Perennials Perennials: Flower which does not die at the end of its first growing season. Becomes dormant in cold weather, but blooms again the following year. Most live 3 – 4 years or longer. Nearly all spring flowers are perennials.
2. Perennials Examples of Perennials: hyacinth, iris, daffodil, tulip, poppy, dahlia & mum.
2. Examples of Perennials Iris
2. Examples of Perennials Daffodil
2. Examples of Perennials Tulip
2. Examples of Perennials Mum
2. Biennials Biennials: Complete their lifecycle in 2 years. Produce leaves during 1st year growth. Produce flowers in the 2nd year. After they bloom, they die.
2. Biennials - Examples: English daisy, foxglove, Japanese primrose & pansy
2. Examples of Biennials English daisy
2. Examples of Biennials Foxglove
2. Examples of Biennials Pansy
3. Hardy & Tender Bulbs Hardy Bulbs- perennials which are able to survive the winter outside & therefore do not require removal from the soil in the autumn. Hardy bulbs usually bloom in the spring.
3. Hardy & Tender Bulbs Tender Bulbs- perennials which cannot survive the winter & must be taken up each fall & set out each spring after the frost is gone. They usually bloom during the summer months.
4. Flower Beds & Flower Borders Flower Beds- freestanding planting made entirely of flowers. They do not share the site with shrubs or other plants.
4. Flower Beds & Flower Borders Flower Border- planting which is placed in front of a larger planting of woody shrubs. They are easier to design & are more easily controlled.
