The perianth segments are light greenish yellow and twisted, their margins are wavy or recurved and they are mixed together with the corona segments which are deeper yellow, sometimes green at the tips; the flower shape itself is variable, sometimes being fully double, sometimes only the trumpet being double, while the perianth segments remain single and distinct
