Is It Time For Planting?

This weekend I bought these little tropical plants and I'm wondering if it's ok to plant them.

I know it's going to be warm the next couple of days but I'm worried about the frost that still might pop up at night. Guess I should ask Alan Kasper. f you have any experience with this I need your help. I was at several garden shops and the rose bushes are ready to be put in and some trees, but I'm wondering about some flowering bushes or flowers themselves.

I would love to know what you think? Can I plant these tropical trees today?
