Nice plants and blooms.
Love your Lutz Rollke. I just had my L.R. come into bloom for the first time.
My colours are pastel yellow that transitions to light pink about 1/3 way out the lateral and dorsal sepals.
The only difference is their length. My flower has same proportion as a Socerer's Apprentice, Eric Young, etc... I like the influence of the caudatum. Kinda like Mystic Dragon.
