How do I know if my GERANIUMS are perennials?
There are Geraniums and there are Pelargoniums. In the botanical world, they are both classified as perennials. Geraniums are commonly called Crane's bill or hardy geraniuns and vary in hardiness. Some are quite hardy and have varying foliage shapes and flower colors. For care, these need part shade (there are a few that can tolerate sun but since you don't know what you have, put in part shade), they like moderate water and are winter hardy so leave alone in winter and let them go dormant. Pelargoniums are commonly called Zonal Geraniums and, while they are perennials, they are treated like annuals frequently. For care, these like sun to part shade with moderate water. Do not overwater these. They are hardy to around USDA Z8 or so. For your climate, you can bring them in during the winter and place in a sunny window or basement and overwinter them there until spring arrives and frost has passed.

What is the difference between annuals, bi annuals, perennials?
Annuals bloom and live until the winter frosts, then die forever. If you let the bloom go to seed, the seeds will re sow themselves in the ground, producing new annuals the following year. Bi-annuals grow for two years, with the largest and most showiest bloom in the second year, and then die. Some bi-annuals (such as lupine) can reseed quite aggressively. Perennials return year after year, and do not need to be replanted. However, if you live in an area that doesn't see winter freeze (such as southern California), certain plants like Geraniums, Jade plants, etc. that normally are considered annuals can live for many years.
Annual V. Perinnial?
Annual flowers grow, bloom, drop their seeds and then die. All conditions being favorable, their seeds will come up the next year. Perennial is a plant that grows, blooms, and dies back in the winter and will regrow from its own roots. Biannual (U didn't ask) will bloom twice a year.
Is "Moonflower" annual or perennial?
I planted seeds from moonflower sometime before May, and I have 2 questions concerning it. First of all is it annual or perennial. My mother things it is putting far too much effort into making it's stem to be only annual. Second, it hasn't actually flowered yet, should I be worried? Bear in mind it had been growing for quite a while. It has grown about 2-3 feet in either direction (there are two vines), shouldn't it have at least shown some signs of making flowers by now?
