Have you ever heard of a parti-colour Clivia?  This refers to Clivias that have flowers that are missing colour pigment on their petals in patches.  It's often called "ghosting".  Fortunately this usually happens in patterns so the outcome can be very attractive like in the flower pictured here that is currently blooming in the nursery.  

This one is from a strain of Clivias called "Florid White Lips" that are line bred to produce this trait.  We should have more parti-colour Clivias in flower at our plant sale on the 24th September 2016.   Each is unique, so it's best to buy them in bloom.
