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 making a decision about when it's the best time to plant chrysocephalum is to refer to the USDA zone info for Oxford.

Planting Calendar for Chrysocephalum

When to plant:	After the last frost.

It's probably a bad idea to plant chrysocephalum until after the last frost has passed because they do not do well in cold weather.

The earliest that you can plant chrysocephalum in Oxford 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 chrysocephalum and expect a good harvest is probably August. Any later than that and your chrysocephalum may not have a chance to fully mature. If you are starting your chrysocephalum indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Oxford the average date of last frost happens on April 15. You can expect an average low temperature of 5°F in the coldest months of winter.

It's important to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Oxford and it will vary from year to year. Half of the time in Oxford it frosts late in the year after April 15 so be sure to be ready to cover your chrysocephalum in the event of one of those late frosts.
