It's probably a bad idea to plant lantana until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant lantana in Missoula is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant lantana and expect a good harvest is probably August. You probably don't want to wait any later than that or else your lantana may not have a chance to grow to maturity. Starting your lantana indoors is a great way to get them started a little bit earlier.
