Yes! you can burn any wood, if you are burning for supplementary heat anyway. If wood is your only heat source, i would suggest oak, locust, or hickory. they are the best. easy to split and produce a lot of heat and last a while. cherry is a good one too. Bradford pear is decent wood. i rank it as about as good as maple or gum, which is fairly decent. definitely beats poplar. anyway don't burn pine, the creosote will clog your chimney. but heck yea burn the Bradford pear and get something out of it. they break so easily.
Birch is excellent fireplace wood.
No, it will explode.
Yes. Cedar is safe to burn in your fireplace, but be careful because it burns fast and hot. It also tends to pop like a bad guys joints in a Chuck Norris film. I wanted to add to the first answer by telling everyone that not only can you burn cedar, I would highly recommend it. Cedar is an excellent source for kindling (fire-starter), because it burns very hot. The down side is that it also burns very fast. This species is also extremely aromatic, vocal (lots of cracks and pops) and creates a warm glow. Next time your snuggling up with your partner, try starting a fire in your fireplace with some cedar. Once the cedar gets ripping, add some slower burning wood such as maple, oak, poplar, alder, etc. Add a little cedar occasionally to get the crackles going again. Please don't rush out and cut down a cedar tree. Instead, find some dead fall or buy some at your local conglomerate hardware store. (Hint: split rail fencing is often made of cedar and is awesome to split and burn) Enjoy.
Sure can. Tends to burn hot, and pretty fast. Would suggest burning cedar as a mix with other woods for best results. In an open fireplace, it will crackle and pop alot. So care needs to be taken. As always, make sure its good and dry. Good starter wood.
Cedar is a great wood to burn if you want to repel bugs. I wouldn't stop with wood though, there are a number of plants you can burn as well. Some plants to try are citronella, lemongrass, rosemary, and thyme.

Yes it can
Check with Martin for an owner's manual. Unless a fireplace is specifically rated as multi-fuel, a gas fireplace cannot safely burn wood.
