HIGH WATER MARK is for me, and gave me VICTORIA. NANA NANCE has been as well, and the two of them together is magical. Below is a NANA NANCE X VICTORIA kid.
Taking VICTORIA to TETRFK produced huge blooms with open throats/watermarks and a variety of colors....green, chalky white, pink, lavender. The plant form is perfectly open to show them off in the best possible way. I think using EMERALD TARANTULA could give you amazing results. I have some HIGH WATER MARK X ET seeds in my keeper bag. I also have seeds from this cross in the keeper bag too!
Good luck! PS - Davi is the queen of watermarks, and would be the best person possible to ask about plants and direction.
