The ultimate decider of plant life is temperature. The gardening season begins in early April, when the last of the frigid nights have passed and the plants have decided it is safe to send forth vulnerable new shoots. Early in the summer, when the sun is shining brightly, there is a burst of growth- flowering and fruiting. Plants, on the other hand, stop growing when the temperature drops below freezing in the fall and winter. Annual plants shrivel and die in the winter, perennials concentrate all of their energy and resources inward and prepare for the dormant season, and biennials only go dormant once before their life cycle is completed.

Difference between annual biennial and perennial plants

Annual: Annual flowers bloom in the year that they are started from seed or planted, with many types being directly seeded in the garden. When annuals begin to flower, they usually do so for a long time before ceasing, when the coming of cold weather in the fall kills them.

Biennials: Biennials are plants that are planted one year, grow for the entire year, overwinter as a plant, and then grow and flower the following year. The plants will produce seed after flowering is completed before dying. It is suggested. Biennials should be planted for two years in a row to ensure year-round flowering.

Perennial: Perennials are resilient enough to endure our harsh winters and return year after year from the same root. The majority of perennials grown from seed (with the exception of those started early inside) will not flower until their second growing season. Unlike annuals, which bloom throughout summer, perennials bloom all year. Although some perennial species flower for much longer, the flowering season is usually between two and four weeks.

Classification of plants

Annuals

Annuals are plants that have a single growth season to complete their life cycle. In the course of a year, annual crops germinate, grow, produce seeds, and die. 

3 types of annual plants:

Tender annuals (also known as summer annuals), hardy annuals (also known as winter annuals), and half-hardy annuals are the three types of annuals. The ability of a plant to endure frost and colder temperatures is described by these phrases.

• Tender annuals: Warm-weather crops, tender annuals have little to no tolerance for chilly temperatures. Basil, cilantro, angelonias, begonias, and marigolds are examples of sensitive annuals
• Hardy annuals: Hardy annuals are the ones that can withstand the cold and frost the best. Broccoli, cabbage, radishes, spinach, peas, and annual flowers like larkspur are examples of hardy annuals
• Half-hardy annuals: Half-hardy annuals may tolerate freezing temperatures to some extent, but they aren’t as tolerant as hardy annuals. Cauliflower, lettuce, baby’s breath, cosmos, and zinnias are some examples
• True annuals are not all plants grown as annuals. Even though they are technically fragile perennials, many vegetables and flowers, such as black-eyed Susans, geraniums, tulips, nasturtiums, and impatiens, can be grown as annuals. If a perennial plant is too sensitive to withstand winter conditions, it can usually be grown as an annua

Perennials

Tender, hardy, and half-hardy perennials are the three types of perennials.

• Tender perennials: In cold climates, tender perennials may need to be brought indoors, but in warm climates, they can grow all year. Sweet potatoes, yams, eggplant, tomatoes, coneflowers, geraniums, calla lilies, angelonias, petunias, snapdragons, and dahlias are all tender perennials
• Hardy perennials: Perennials that are hardy can withstand cold and frost. Hardy perennials include asparagus, fennel, potatoes, rhubarb, sage, and perennial flowers like hydrangeas
• Half-hardy perennials: Perennials that are half-hardy can resist freezing temperatures to a degree, but not for long periods of time. Daylily, hosta, and mint are examples of half-hardy annuals

Biennials 

Biennial plants are those that go through their entire life cycle in two years. Biennials germinate in the fall or spring and form roots, a stem, and leaves before falling dormant the following year. Flowers, fruit, and seeds are produced the next year. Flowers like foxgloves and hollyhocks, as well as vegetables like dill, kale, carrots, celery, and Swiss chard, are true biennials. Biennials, like annuals and perennials, can be hardy, semi-hardy, or delicate.

Examples of between annual, biennial and perennial plants

Examples of annual plants: Mustard, watermelon, lettuce.

Examples of biennial plants: Carrot, cabbage, onions.

Examples of perennial plants: Mango, coconut, banana.

Conclusion

You could be familiar with trees that lose their leaves in the fall and then regrow them in the spring, but this is only one of the seasonal development cycles that plants go through. Before we look at the three different sorts of seasonal cycles, let’s review what seasonal growth cycles are. Several variables influence seasonal growth cycles, including temperature, water availability, and daylight. These elements influence how plants regulate their developmental processes. Where plants live, how they reproduce, and the function they play in their habitats all influence their seasonal growth cycles.
