I have a fair number of F's to share but before I do, here's a couple of chuckles...

...and on with the meat of the thread. First up is:
'Fantasy Island'
'Feather Boa'

'Firn Line'...story goes there was a mix-up/mistake in the registration process and the name for supposed to be 'Firm Line'...

This cultivar, like it's relative 'Blue Ivory', is prone to exhibiting a kind of bleeding which is thought to be brought on by stress; that could be moisture related or temperatures. While somewhat unsightly it's nothing of a permanent nature.

'Fortunei Albomarginata', often referred to in the trade as 'Albomarginata' which label we also applied to 'Undulata Albomarginata'. Side by side the two are easy to tell apart, the glaucous one is the Fortunei variety. There's also a slight overall difference in colouration, as you see here in the second picture.

'Fortunei Albopicta' is a viridescent variety that can turn almost a solid green by season's end. How quickly it looses its variegation seems to depend on the amount of direct light it receives.

The picture above is from early May, the one below is from mid-July and the variegation has gone pretty green by now.

'Fortunei Hyacinthina' is frequently just called 'Hyacinthina' and is the progenitor of a massive number of sports, sports of sports and sports of sports of sports.

It's time to go horizontal, I hear the bed calling... I'll do the remainder tomorrow...
