while on the above link for Jactorse I wanted to see what it said about Jacfrain. So I clicked on that link:
I scrolled down to "comparison with similar variety". The way I am reading it, it says Jactorse has a cream reverse. But yet on the previous link it states a pink reverse.
"COMPARISON WITH SIMILAR VARIETY
Although it is difficult to find a comparison variety, ‘JACtorse’ (U.S. Plant Pat. No. 12,129) is an example variety. ‘JACfrain’ differs from ‘JACtorse’ in flower color (yellow, pink, orange blend for ‘JACfrain’ versus deep pink with creamy reverse for ‘JACtorse’) and in fragrance (apple for ‘JACtrose’ versus musk for ‘JACfrain’)."
I found more info on various forums. Some people stated it had a white reverse, others apricot and yet others creamy yellow. It's a good thing I took photos. It's almost unbelievable that the reverse petal color changed so quickly in a matter of a few hours.
Here's the RHS cards for reference
This is so confusing.
