It's to Iowa we travel this week, to visit the gardens of Larry Rettig and his wife, Wilma. I've been fortunate, I met Larry's Amana Colonies garden face to face earlier this year. I wandered those garden paths for days and every day I found something new. Let's take a look at these unbelievably beautiful Iowa gardens.

I have the Corydalis lutea, which is the yellow form of this plant. It's in a very dry shady corner and survives quite well my zone 5 winters. When I bought it, I bought it as a little plug in 2011, in 2012 it was about a foot across & spreading. Not very generous with flowers, but apparently needs a lot more water than I've given it. I've treated it very xerically.
