Several people have asked what could be planted for summer. Although it is getting a bit late to plant some crops, others can survive the summer heat. The most useful list of crops comes from the Univ. of Florida, IFAS (Institute of Food and Agricultural Science), and I highly recommend checking their recommendations.

Note that the Northern Region is north of Rt. 40 (Granada Blvd., Ormond) and the Central Region is south of Rt. 40 to Rt. 70 (Ft. Pierce). We are at the very, very northern end of the Central Region and I think you should check the Northern Region planting guide also. You'll have to make some judgement calls, but since we are so far north, there is a bit of overlap in crops from the North and Central Regions.
You can download (PDF format) this entire page from IFAS (download button at the top). That way you will be able to print it out and refer to the planting guide.
There are several other links on the EDIS website (Electronic Data Info. Source) that are useful for Florida gardening and landscaping.
