Answer 1

A perennial in the broadest horticultural definition is any plant that lives for three or more years. The definition covers a lot of ground, embracing both dandelions and giant redwoods and thousands of species in between. But when gardeners talk about perennials, they almost always mean flowering garden plants with stems that are herbaceous,i.e., fleshy rather than woody, and that usually die down to soil surface during the winter, while the roots remain alive and ready to send up new growth next season. Bulbous plants such as daffodils, and tulips are perennials, but they generally are classified separately because of their method of storing food for the next years growth. What sets perennials apart from annuals and from biennials, is the durability of their roots. Here are some examples of herbaceous flowers:
Achillea{Yarrow}, Aster, Canna, Coreopsis,Delosperma,Dianthus,Echinacea, Daylily,Iris,Lobelia, Monarda,Peony,Phlox, Rudbekia{black eyed susan], Salvia, sedum,Stokesia, Verbena, Veronica, this are all for full sun and just a few examples, here are some flowering annuals Ageratum, Angelonia, Begonia, Calibrachoa[Million Bells], this annual is a perennial in n.e. Georgia, Brugmansia[angel's trumpet], Gomphrena, Impatiens,New Guinea Impatiens, Lantana, Petunia,Surfina, Plumbago, Salvia,Scaevola, Torenia, Verbena, Vinca, Zinnia. Hope this helps you today.

maximum perennial's die in the fall and reckoning on the wintry climate and the age of the plant maximum of them come again up in the spring yet some perennial's don't have an prolonged smart lupines.I continuously via a plant and then come homestead and look it up on internet to be sure what they say approximately it like if there are ailments that it gets or bugs to learn-sorry I kinda have been given off beam right here-yet I stay in Montana and we've in simple terms have been given by using a real chilly spell and that i've got flowers out side that are nevertheless green so it quite relies upon on the plant and as for the annuals I do have some annuals that come again twelve months after twelve months a number of them come again from the main plant yet alot of them come again from the seeds that died in the fall like pansys and Marigolds.

Answer 3

Yes they do unless they are evergreen type perennials (gardenia, azalea, dianthus, shasta daisy, thyme, oregano, mints...) Black eye susans and yarrow (medicinal) will reseed as well as regrow from roots. Too many to go into further detail individually. What, specifically are you interested in?
