In Bloom Today - Rebutia 'watermelon'

As cacti go, the South American species reign as the most colorful and floriferous, especially the Rebutia species. I keep many in the cold greenhouse, where they spend the winter dry as a bone, under the protection of glass. They freeze a little, since they are kept near the glass in the coldest of corners, but in full sun. With this treatment, once watering starts in the spring, flower buds form quickly. This named cultivar blooms later, in late July, but most bloom for us in June in colors which are hot and bright, in most every shade of gold, pink, orange and red.
