Flat dorsal has over 7cm dorsal and Semi-vini is also very large with 6.5cm dorsal. Hope for the best! There are two color variety options. Although these haven't bloomed yet we can tell the color variation of the plant by looking at the leaves before they bloom. Vinicolor is a darker flowering variation where the red tones show as more deeper red wine color. in bud/spike is available (BSB). Limited!
