This is the year we tackle the front yard. We did a vegetable garden last year with mixed results (lots of growth, but not enough food to make me feel all the work was worthwhile), so I feel a little more confident about my gardening abilities. I didn't want to try a front yard garden before I conquered my black thumb, because, after all, it will be on full display for everyone to judge and potentially mock.
Right now we're in the budgeting/planning phase. A great site I found for information is BHG.com - they even have free garden plans which give you all the details from what flowers to buy, to how to properly plant and take care of them.
I like this one for the area near the sidewalk, which has a slight slope. Plus, we could use a nice path from the sidewalk to the front door since we currently cut across our neighbor's yard, which is probably a big faux pas.
My top 3 goals are to find plants hardy enough (and low-maintenance enough) that they won't die from the extreme Texas heat or my general lack of gardening mojo, that are cheap (you know it), and are mostly perennials so I don't have to replant the entire garden every year.
