A biennial plant is one that takes two seasons to complete its' lifespan. The first year they come up as small plants in the fall, they go dormant over the cold months and then come up and bloom the next spring/summer. These plants can also self seed.
Perennials are plants that come back year after year.It usually takes 3 years for them to become really well established in the garden. There is a well known gardening saying about perennials, the first year they sleep, the second year they creep, and the third year they leap. If you have the patience to wait for them they will make an easy and beautiful addition to your garden and you can use them as a Christmas Tree.
Annual plants grow from seed and flower, make seeds and then die in one season (year).
Biennials grow from seed in the first year and over winter to flower, make seeds and die in the second season (year).
Perennial plants grow from seed and then come up year after year to flower and make seeds, surviving many winters (years).
Not all plants fall into the above categories neatly, Some perennials are monocarpic and live for many years before they flower and set seed, after which they die (bamboo and century plant)
Annuals germinate grow and set seed and die in one year. Biennials germinate, grow and set seed and die in two years.
Perennials germinate, in the first year, grow and live for many years setting seed every year.
Annuals complete their life cycles in one growing season. You plant them afresh every year or let them reseed themselves - the same plants generally won't come back the next year. Biennials are similar but take two growing seasons instead of one - foxgloves and hollyhocks are good examples of biennials. Perennials are plants that last longer than that; herbaceous perennials are the kind that aren't woody. Most herbaceous perennials die back to the ground during the winter and return in the spring.
Sometimes it depends on your growing zone, though - some plants may be perennial in one climate but too tender to survive the winter in another.
Biennial: Flowering plants that take two years to complete their life cycle. Perennial: Any flowering plant that lives for more than two years.
No.
Both annuals and evergreen perennials. For example the Balsamina and the Gladulifera are annual and the New Guinea group perennials

Are maple trees annuals or perennials?Maple trees are perennials.
They are perennials, but are usually grown as annuals as they tend to deteriorate in appearance after a while. You can propagate them easily from cuttings.
Non-perennials (which basically are either annuals or the rare biennial) are plants that grow for one warm season, then die (or in the case of biennials, two warm seasons). Many vegetables and cheap colorful flowers from the nursery fall into these categories. Perennials are more long-lived plants, which you don't have to replace every year. Trees, shrubs, and some herbaceous plants such as mint, alstroemeria and tulips fall in this category.

Angiosperms are classified as annuals, biennials, or perennials based on the length of their life cycles. Flowering plants that complete a life cycle within one growing season are called annuals. Angiosperms that complete their life cycle in two years are called biennials. Flowering plants that live for more than two years are called perennials.
The flower that people recognize as a "carnation" (Dianthus caryophyllus or clove pink) is a herbaceous perennial plant. Within the carnation or dianthus group of flowers there are also annuals, biennials and even low subshrubs with woody basal stems.
There are dozens of marigolds, and some are annuals while some are perennials.
There are many varieties of daisies. Some are annuals and others are perennials.

They are perennials. They are very hardy plants!
