Hoho Terry!
Focus, that's a tricky one. I only have one third of an acre. My yard limitations make me focus to a certain extent. Not a complaint, because I think a larger yard would have finished me a long time ago. I can manage 1/3 of an acre.
I also like surprises. My new seedlings are leading me, more than me leading them. Sure, I knew what I wanted when I made some of my crosses. Getting more than I wanted is always a treat.
I guess you should trust your instincts. I have never had a daylily that grew on me, that I started to like after a few years. I have an immediate gut reaction. Go with that! The first time I saw ROSE F KENNEDY bloom in my yard I knew I was off in a new direction! Or CAROLINA COOL DOWN, a great watermark will stop me in my tracks every time. The intense color of TOURNAMENT OF ROSES and RUBY SPIDER still demand my attention.
Like it was said earlier....have fun!
