I'm a beginner beekeeper and have my one hive so far on a farm where we also keep two donkeys. Last season it seemed that all of August was pretty much a dearth as far as the bees were concerned and since we have a nice unused field I was considering growing something to get them a bit of a flow that time of year. Since we also keep the donkeys I was wondering if I could use some kind of crop that would provide a good flow for the bees in August and then dry up and be a decent feed or at least something to make the "beds" for the donkeys.

Any ideas for a crop that fits my requirements:

- Blooms at the end of summer when the bees are in a dearth
- Ideally doesn't need much water but I have plenty of water to irrigate in August if needed
- Come fall, dries up and can be consumed by donkeys
