One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

You can estimate when it's possible to plant lantana in Wyoming by reviewing the USDA zone info.

Planting Calendar for Lantana

Frost tolerance for lantana:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Lantana do not do well in cold weather which means that it's necessary to wait until it warms up after the last frost has passed before you can plant them.

The earliest that you can plant lantana in Wyoming 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 really do well. Starting your lantana indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Wyoming the average date of last frost happens on April 15. It might get as low as -15°F during the coldest months of winter.

Keep in mind that the actual date of last frost is not always accurate because it is based on the USDA zone info for Wyoming and it changes from year to year. Half of the time in Wyoming there is a last frost after April 15 so make sure that you are prepared to protect your lantana in the event of one of those late frosts.
