One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of figuring out when it's possible to plant lantana is to use the USDA zone info for Oregon.

Planting Calendar for Lantana

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

Since lantana require warm weather it is necessary to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant lantana in Oregon 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. If you wait any later than that and 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 Oregon the average date of last frost happens on April 15. It might get as low as -20°F during the coldest months of winter.

Always keep in mind that USDA zone info for Oregon is not always accurate and the actual date of last frost is different every year. Half of the time in Oregon you get a frost after April 15 so always be ready to cover your lantana in the event of one of those late frosts.
