Dear Elizabeth, Sunflowers are indeed a good source of pollen and nectar. Honey harvests may be influenced by e.g. Climate, soil type, cultivar, evening temperatures and adequate soil moisture. Black soil types (In South Africa) tend to yield more honey than sandy soils. There is also a nice build up of your bee colonies when they are working on sunflowers. My experience is that sunflower honey granulates quickly when temperatures drop. Do not leave your crop on the hive for too long. My hive placement is about 1 hive per 5 ha sunflowers during an average to good season. Hope this helps.
