I was curious about planting flowers through the winter that will
bloom in early spring such as tulips and other early bloomers. Does
anyone have any tips?

I'm sure others will chip in, but in most temperate climates, among
commonly grown flowers, the first to come up are the crocuses and the
second are the daffodils (narcissuses). Both of those are earlier
than tulips.

You buy those as bulbs and plant them in the fall (well, crocuses are
technically corms but are grown the same way). See for example
http://www.vanengelen.com/ or your local garden store. Growing
instructions at http://www.vanengelen.com/plantinginstr.html .

In my own garden, I'm also trying to figure out what the native plants
which come up first in the spring are, and incorporating some of them.
Here in the Washington, DC, area, that's things like Hepatica,
Mayapple (which comes up fairly early although it flowers later),
Sanguinaria, Trillium (a few weeks later), probably some others I'm
forgetting right now. (Your region may vary). But that's a bit more
investigation than just running out and buying some garden store
crocuses. Even when/if I have a lot of natives I doubt I'll give up
the crocuses entirely.
