Answer:
Most common vegetables are annuals. Your standard greens - lettuces, mustards, spinach, chard, etc - all put out leaves, get bigger, go to seed, and die, in less than one calendar year. Those seeds may come up and produce new plants the next year (depending on your garden conditions); those are often called “self-seeding” in plant catalogs but the plant itself is still an annual. Carrots, broccoli, squashes, peas and beans, are all other examples of annuals.
There are some plants that are sold as annuals that in warmer climates are actually perennial, it’s just that they won’t live through the winter in most of the United States. Mediterranean herb plants like basil fall into this category.
Biennial is a relatively rare life cycle overall for a plant. The only truly biennial plant I can think of off-hand is certain species of foxglove, and eating those flowers is not recommended!
Perennial crops are going to be pretty much anything grown on a bush or a tree, first off. So your fruits - oranges, lemons, apples, pears, etc - and tree nuts - pecans, walnuts, and so forth.
One interesting example of a perennial that most people don’t think of is asparagus. The asparagus plant dies back in the winter but the roots stay alive, and it puts up new shoots every spring. Asparagus actually doesn’t produce any edible stalks until its third year or so in the ground, and production improves after that. I’ve only had mine for a couple of years but I’ve read that they can produce reliably for up to 20 or so.
Answer:
Here is the answer..
Explanation:
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies.
eg Morning Glory, Basil
A biennial plant is a flowering plant that takes two years to complete its biological life cycle. In the first year, the plant undergoes primary growth, in which its leaves, stems, and roots (vegetative structures) develop.
eg Parsley , Cabbage
A perennial plant or simply perennial is a plant that lives more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials.
eg Peonies, Day lillies
