One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Walnut you can estimate when it's a good idea to plant matricaria by reviewing the USDA zone info.

Planting Calendar for Matricaria

When to plant:	Up to 5 weeks before last frost.

Matricaria can survive in a little bit of cold which means that you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

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