One of the first steps you take when you are estimating your gardening schedule is find your 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.

In Scottsdale you can figure out when it's possible to plant fanflower by referring to the USDA zone info.

It's probably a bad idea to plant fanflower until after the last frost when the weather gets warmer because they do not do well in cold weather.

The earliest that you can plant fanflower in Scottsdale is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant fanflower and expect a good harvest is probably September. You probably don't want to wait any later than that or else your fanflower may not have a chance to really do well. You can get started a couple of weeks earlier by starting your fanflower indoors.
