Rebutia heliosa

One of my favorite cacti of all time is Rebutia heliosa.  We don't have flowers at this time of year, of course, but I couldn't resist taking a photo of these plants whiling away the short days of winter. Even without flowers they're quite attractive I think.

From Bolivia (Tarija) in the mountains (3000 m), these little tap rooted gems get no water during our winter and get filtered sun and limited water during the summer. As long as one follows this or similar regimen these plants are quite easy to grow and are very rewarding.
