lakota: good idea on the "edible hedge".  Here in Zone 8, I haven't found any raspberries that I like, but plenty of commercial blackberries, and they make a dandy hedge.  They will send out runners 4-6' laterally every year.  I have to keep them mowed to make a line rather than a clump, though; left to themselves, they grow in a clump. 
 
Most years, I buy the 3" peat pots in bunches when they have them on special, make my own potting soil from slow-release fertilizer and compost, and start from seed whenever I can.  Just finished transferring the seedlings in the peat pots to quart&half gallon containers today.  Sometimes it's easier to buy tomato and cucumber plants from Wal-Mart or a feedstore...the $1.65 for a six-pak size...and let them grow inside until they get to the right size.
 
I'm growing a couple of native squashes from heirloom seed from baker Creek:  the "Seminole Punpkin" and a "Tinda", which is classed as more of an edible gourd.  These, and the butternut/acorn, will run on the chain-link fence, or one of my berry patches.
