Well let's put it this way...of the four I have...three have identical shaped leaves - NONE have red blooms. Sooooo....I can take cuttings off of at least 2 of the 3 pointy shaped 'leaved' ones which are both shades of pink. I don't think my little apricot colored blooming one is big enough nor the 1 rounded shaped 'leaf' one I just picked up last week. I think I will name them myself...my grandmother's (I've had for 23 years and it blooms whenever it feels like it...much like her) will be named after her. It will now be called the Molly Cactus (she'll love that). The other I rec'd from a patient about 10 years ago and despite my neglecting it at times it continues to remain alive and bloom for me. It will be referred to as the Patient Cactus.
Happy to shove starts from either or both into soil.
