AY Honors/Flower Culture/Answer Key

1. Define each of the following:

a. Perennials

The plants grow all year around without dying back. Some may enter periods of foliage dormancy but their root systems will remain viable and they will normally remain green although not showing new growth.

b. Annuals

Annuals die each year. Depending on your climate annuals may be for summer planting (in snow regions) or winter planting (in low deserts). These plants produce many flowers and seeds in their life cycle to help perpetuate them. As a result many annuals seem to grow back each year when it is more likely a new plant from a seed has grown in its place.

c. Biennials

Biennials are plants that live for two years. They generally take on different forms in each of these years, producing seeds only in the second year.

10. What is the purpose of a soil test?
