I have a few good sized beets now from a spring planting. Still a lot of small ones. The seeds were called Rainbow Beet Mix from The Cook's Garden. Its described as a mix of all of their beet varieties that will mature at different times over a long season.
An added comment on the weather: I thought this was fall. Its as hot as mid-summer today! Good thing I planted a lot of fall crops. If this keeps up, my garden will grow until Christmas! And my nice fall sweaters will stay in my closet.
