In the way back corner of our property is a small quarter circle garden next to the big hurricane fence and work gate. I have planted a lovely Possumhaw holly, some sages, milkweed and Artemisia ‘Powis Castle’. It is meant to be a wildlife garden. The birds must have heard and decided to plant Black-eyed Susans (Rudbeckia hirta).
These flowers just love this corner of my garden. They come back every year and I swear they grow taller every year.
I have read that they are suppose to be around 2 to 3 feet, although the Farmer Almanac said or more : ). You can see ours are already taller than the neighbors garage. Perhaps it is our healthy soil and the seaweed extract we put through our drip-tube irrigation system now and again.
I am hoping the birds have a nice little feast. In fall when all the seeds are spent we cut them down and I then I work on the garden to make it pretty for winter.
