This is an unusual and rather rare color code. Voo-67-11; 2W-YOY, is from: (Random Event x La Paloma) x (Amity Angel sibling x Yum Yum). Both are my seedlings from 1992. The corona is straight sided and slightly flaring. It does not look like a Div. 3 corona but a Standard Div. 2 corona of just under half length. There is a 2mm yellow band at the mouth of the corona which does not show too well in the photo. The flower is hugely consistent and a rapid increaser.
It is of a different character and color.
