I live in an area with typically 150 - 200 inches of rain (although not this year) and a temperature range of 55 - 85 - but mostly 60-75 degrees. Soil tends to be on the acidic side (volcanic soils) I'm interested in knowing if there are varieties of sunflowers that will grow in these conditions and also are good for honey production. Thanks
