Feverfew Crop Yield

If you plant feverfew from seed in the spring will you get seed from the plants the first year? How many plants do you need to produce 10lbs?

Weight-loss from drying herb is averaged at about 82% to bring it down to 12% moisture. That means to have 10 lbs. at 12% (dry) would require about 83 lbs of fresh-cut feverfew.
This is about true for almost any herb-cut crop such as alfalfa.
[Yes, you will get a crop the first season in most temperate zones. For more information about growing feverfew, including seeding rates and crop yields see www.richters.com/progrow.cgi?search=Feverfew --Ed.]
