Answer: It's hard to say what may be causing this abnormality without more information about the environment, age of the plant, and the species, but if this is a calla lily, it prefers a rich, humusy soil and ample moisture. If you've had dry weather, this could cause stunting of new growth, as could insect or disease attack. I wish I could be more specific! If you can find out exactly what the plant is, I can give it another try. It's also helpful to get a close look at the plant to see if it has sustained some kind of damage from insect attack.
