Buy an adult of a certain species, pot it up and let it get healthy new growth to take over the old growth, then take some cuttings.
Drosera capensis can survive most weather outdoors in hardiness zone 6, which includes Pittsburgh, PA, and Harrisburg where I live. They get about 6" tall.
Capensis are sub-tropical; I think our PA winters would kill them, but in nature they often go dormant for winter even though they can be grown year-round as tropicals. So we should be able to grow them outside in the spring/summer and put them in a sunny window sill during winter anytime temps are dropping below 40ish at night.
They grow extremely easily from leaf cuttings and seed, are very hardy, and curl around trapped prey within about an hour or two.
Matt sells capensis 'Alba' (albino)
but I think is out of Red, and Andrew's store has capensis Broad Leaf (standard green) and Red
Yes you can get the cuttings to take in water. Use these links if you want details:

Alternatives to capensis would be temperates like D. intermedia
, filiformis, binata, rotundifolia, anglica, etc.
Adelae are picky little jerks.
Here's a grow guide that will help troubleshoot it: http://www.growsundews.com/sundews/adelae.html
Most common problems with adelae are:
1. Most commonly not enough light = no dew. 12 hours or more per day with fluorescents, I'd guess at least 8 with sun.
2. If in direct sunlight for several hours a day, try 30% to 65% shade. Heck, if under strong artificial light try 30% shade.
3. Temps above 75-80ish can make it angry and it won't produce dew. Ideal temps are closer to 70 or even a little below that.
4. Not as often an issue, but play with humidity if your humidity levels are low (below ~50%). In nature I believe they're found primarily in areas with fairly high humidity.
