It can be very enlightening to visit a hybridizer's garden before buying his/her plants. When I see someone who grows/crosses in a greenhouse or who has customized soil with every imaginable amendment/fertilizer added I know that "results will vary" when that plant gets to the home of an average gardener.
I have lost several of the Carpenter plants from the Kaleidoscope/Super Fancy Face lines. They are beautiful but lack the substance and vigor I like to see in my DL.
