There's always more room... 
I meant seeds from a plant with black flowers. Not sure what they have been pollinated with though... Who knows. My friend does have some nice cultivars.
Oh wow! Hope you are able to get them. Most of the "black" have deep purple or deep red undertone.
I have not ventured on any hybridizing yet. So just counting they produce seeds via self or bee pollination.
