Darwinara Rainbow is a cross between Darwinara Charm ‘Blue Star’ and Neof. falcata Tamakongo. Plants are vigorous growers, and color varies among plants.
I grow Darwinara Rainbow in mesh baskets with very chunky bark and charcoal or Growstone. The roots grow very vigorously. Very easy to grow: intermediate light, warm to cool temperatures, and water well then allow to dry out. In hot or dry conditions, you can water it every day. If you find that the roots are drying out, add more chunky mix to the pot or basket to maintain more humidity around the roots.
