I have been picking up Heucheras that say Kira Jersey from Lowes and HD for a few years. They seem to survive for me. At first everyone I purchased said Kira Jersey. I started to notice that may be the name but they looked different.
Today I decided to google Kira Heuchera and found they look different because they are not all Kira Jersey. There is a Heuchera Kira Series by Danziger “Dan” Flower Farm.
What I found interesting and thought this article was interesting.
It comes from a magazine called
"Grower Talk"
How to Have Success with Heuchera Chanochi Zaks
In the article it said..................
Fertilization: Heucheras require high fertilization levels. Fertilize the crop weekly with 130 to 150 ppm of nitrogen. Avoid high ammonium levels. Don’t fertilize after mid-September.
