I finally found a use for the post! Ordered this yard sign from Wild Ones, an organization that promotes native landscapes. The sign says:

Wild Ones
Native Plants, Natural Landscapes
Toward Harmony with Nature

I thought it was appropriate, and will look nice when there are some plants growing in. Also it really dresses up the post, so I'm glad I didn't cut it down. My goal is to get a photo of a bluebird perched here. I've already seen one on it since we've had some bluebirds come through this month.

Behind it you can see some additional native shrubs ready to be planted, that I purchased from Outback Nursery. I got two winterberries and two nannyberries.
