These spectacular flowers are really Over the Top! The heart of the large 7 flower has white at the base of the hot pink petals highlighted with a red mid-stripe. The next row of petals is dark pink with an orange overtone. The outer petals are bright orange with deep red edges. Orchid cacti are easy growers that bloom in spring. They are forgiving of forgetful watering but remember to give cool nighttime temperatures during the winter to initiate bloom.
