Rebutia senilis var lilacinorosea, is a lovely cactus that is native to Argentina.
It is solitary or clumping and in age can grow clumps 10-15cm wide. It
begins to offset in about its third or fourth year, eventually making a
moderately tight clump, with the individual stems standing out a little
on their own.
Each head is surrounded by a complete ring of pink-violet flowers produced from around the base of the plant.
Hardy down to -4°C.
