frost ?

czecheartMay 24, 2013

We sowed some wildflower seeds yesterday. We were told OK to sow after last chance of "killing frost".

Woke up today with frost on the roof. The temperature got down to 32. last night. We could see no visible signs of frost elsewhere.

What do you think , are the seeds still going to be viable?

The seeds should be fine. There are many kinds of seeds that won't germinate unless they are subjected to alternate freeze/thaw cycles, the kind of weather they would have to endure if the seed fell off the plant in the fall, and sat on the ground all winter. Seedlings, the tiny plants that come up in a week or two, are sensitive to frost damage.
