I noticed P. megliolii is in flower as I left the greenhouse tonight, I will try and take photo tomorrow.
Trouble is the flower looked pink in the late evening light, I always though megliolii had yellow flowers

edds it is doing very well

No sun but four buds went for it...

That is one species I struggle with , still both alive but little or no growth. After reading what Ralph says I must have mine too dry.

Mike I am clearly 2 days North of you this year

First a correction the plant at the top of this post is not Lincoln Angel but is Chamaelobivia Sharons Delight.
The two plants in the first picture are Lincoln Angel sorry about that.
Other small plants with large flowers below .

A few more buds

Beautiful Plant .

Gymnocalycium and some Notocactus/Parodias are fine in slight shade and under the bench is as good as anywhere for that.

Ian; Yes the E. knippelianus in my post above has been like that for 3 weeks now, just watered that side of the greenhouse tonight so maybe that might just give it the nudge
