Gardeners' Notes:

Some of my Corn Harvest plants bloom year after year and others only occaisonally. I live on the extreme northeastern slope of the Sierra Nevada mountains - cold winters and temperatures in the mid-upper 80's during summer. I think if they can survive my climate and poor soil, they'll grow anywhere!

This iris was always stunted in my garden. I think it is suppose to be a rebloomer, but it never did. I grew it for 3 years and finally dug the straggley thing up and threw it away!
