Hello David nice to meet you ,don't believe we have met before,if i'm mistaken I'm so sorry.
That is a very old plant it was my moma's and it was neglected for years. When i started getting interested in plants holiday cactus was 1 of the 2 i ended up obsessed with (at 1st.), the other was hoya's.
I have been in the hospital because of having a heart attack and i have a hard time keeping up with the site like i use to but i remember reading someone talking about wanting a yellow HC.Seems i remember it having to do with a family member so that was you looking for a specific color yellow,am i correct?I don't know what forum or thread i read it on but i remember JB showing you some of hers,they just weren't the right shade.
I tell you what i can do is look through my pictures of that plant and post a few more pictures of the flower,that way we can see if my camera has fiddled with the blooms color.
I will just post some pictures and you let me know.I have to send someone else a plant so i would be delighted to send you some cuttings.It needs to be cut back anyway & the last thing i need is more cuttings to propagate!!
BACK TO ORIGINAL TOPIC: I have really had to remember to pay attention/remember (tie a bow around a finger) the ones in terra cotta get more water & watered more often.If i watered the ones in plastic pots as much as the ones in terra cotta the plastic pots would have all rotted away a long time ago.
