A safe time period to plant your flowers outdoors would be mid-May, preferably the 15th-20th. Until then...
"Back Deck" your flowers. This means place your flowers outside on most days but bring in on nights colder than a light frost.
Indoors, your flowers should be in temperatures no warmer than 70 degrees. There is a fair amount of babysitting, but it shouldn't last more than a few weeks.
