I planted some roma plants for the first time this year and have got a lot of tomatoes out of them (up till 3 weeks ago). I thought that they were all done growing and therefore would not bear any more fruit. I noticed earlier this week that all three of the plants were growing more suckers and that those suckers all had flowers on them. So it looks like I'm getting more salsa/pizza/spaghetti sauce!

is this pretty normal for Romas? or should I be saving some seeds for next year?
