No need to apologize. Things can be confusing when merchants supply information that isn't accurate.

Fuchsias are shrubby and they live from year to year. However, plant merchants sometimes refer to fast-growing plants that bloom on new wood as "annuals" because people in climates too cold to overwinter them can treat them as such. They freeze to death and that's the end of that.

I would also suspect that your Fuchsia is probably relatively short, to be used in annual bedding. Now, this is confusing too: Fuchsias are naturally upright, but some have been bred to have weak stems so that they cascade out of a basket. The type that would work best for a basket would be referred to as a "trailing" Fuchsia. Yours might work fine but don't be surprised if it doesn't cascade down the sides of the basket.

Palo Alto is very mild and with irrigation your "annual" Fuchsia will live from year to year indefinitely.

Now, as for what to do with it; what little frost you ever have, you probably don't even get every year, and when you do get it, it's probably not enough to kill a Fuchsia even exposed in a hanging basket. If you are in a hard frost area (for example, in a cold air drainage pocket, or at some elevation), you could still overwinter it by just planting it in the ground and mulching it a bit.

Don't be surprised if it looks a little tired in the winter. It is fine, and will perk up quickly in mild weather.

Fuchsias respond quickly to fertilizer, being especially fond of liquid types, and will usually reward you with a flush of growth and blooms. They bloom on new wood. You can clip to train them. If they get senescent (the wood starts looking like it is dying of old age), you can start them from cuttings and start over again. Fuchsias are extremely easy to root from cuttings--as easy as old-fashioned Coleus were.

Fuchsias like mild weather. Not too hot, not too cold. They like bright open shade. They can stand a few hours of sun as long as it's not too hot (morning sun better than afternoon in that regard). Dry heat is very hard on them--possibly fatal. In dry weather you will probably have to irrigate your basket daily.

If you like Fuchsias, keep your eyes open for Fuchsias that your friends have that you like--they can probably be talked into a cutting. Also consider contacting a local Fuchsia society--they will have hundreds of varieties, probably with bigger flowers, in more variety of colors, than Lowes.

Mine are all uprights that I plant in the ground. Easier to take care of than in a hanging basket, which in my climate, that is colder than yours, I would have to protect for the winter, not to mention water it daily in the summer. I grow them along the north side of a fence, open to the sky but shaded from direct sun. They sit on a bank, and so their flowers are close to eye level. It is a very popular feature for my neighbors to look at.

Some of mine are wild species--not hybrids. They have some variety of form--for instance one of them in habitat would clamber up a tree almost like a climber. Another one has dainy fern-like foliage and tiny but brilliantly colored flowers, and one has berries that are considered tolerably palatable (usually Fuchsia berries are bland). Another one gets big as Fuchsias go--it can hit about 7 feet tall (and perhaps even wider) or so before its weak wood bends under its own weight.

You can grow some I can't--like the beautiful Triphylla types, such as the popular "Gartenmeister Bonstedt". Much too tender for me.
