Answer: Gerbera jamesonii or Transvaal daisy is native to South Africa so they're not very tolerant of cold weather. A temporary cover will protect them from a cold snap so your plan to cover them while overnight temperatures are in the 40's is a good one. Gerbera's thrive in full sun and rich soil with excellent drainage. They prefer a thorough watering and then dry soil, followed by a flooding again. The plants need frequent feeding during the growing season and will produce new leaves and flowers if the old leaves and flowers are pinched off regularly. Plants generally grow about one-foot tall with erect flower stems about 1 1/2' tall.
Gerbera daisies are fussy about watering. Try not to splash water on the crown of the plant. Gerbera daisies like the nightime temperature to be about 60F degrees, and the daytime temperature about 75F. The plant will take full morning sunshine, but appreciates some afternoon shade.
Good luck with your plants!
