Tomatoes, Lavender & Salvia?

Seems to me young tomato plants are prefectly safe at 50 degrees,
although they'd grow faster wigh more heat. Our (established) lavender
seems brutally hardy so I'd reckon youngsters can easily stand some
cool days. Salvia we've grown in the past but I don't recall how hardy
it was. Seems to me it didn't always overwinter (zone 7 maybe 8.) But
surely almost everything will survive 50 plus?

I've done it myself!
