Many of my cacti flower early and this year has been particularly good. Last years star shows signs of being even better this year. I must try and dig out a name for it.
I seem to remember that last year the colour got stronger as they opened. It is also good as the flowers last for almost a week, instead of a day or so.
The next one is a first for me, oroya peruviana, delicate waxy flowers on this one.
Then the mass of flowers which are the rebutias, this one is rebutia x aylostera
The only problem with rebutias is that while they always flower well, sadly the flowers don't last long, only a day or so, so there is a short period when they look this good.
It is good to be out in the green house again.
