Planting Science is a resource for teachers which includes two, free, online units you can also use at home, "The Wonder of Seeds" for grades 7-12 and "The Power of Sunlight" for grades 9-12. They not only include experiments, but information on things like Investigating Plants Safely, Thinking and Working Like a Scientist, and Making Meaningful Graphs.
This site was recommended by a homeschooler, but a quick glance at it makes me think it needs some translation from "biology teacher speak" into regular people language. However, it could give you good ideas for experiments, and you can always Google to find a more novice-friendly version or explanation of what's going on.
