One of the best tools that you have as gardeners to help us determine 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 Snoqualmie you can determine when it's the best time to plant nemesia by referring to the USDA zone info.

Since nemesia require warm weather you really should wait until after the last frost has passed before you can plant them.

The last month that you can plant nemesia and expect a good harvest is probably August. You probably don't want to wait any later than that or else your nemesia may not have a chance to grow to maturity. If you are starting your nemesia indoors then you might be able to get away with starting them a little bit earlier.
