Leaf: The green, photosynthetic part of the plant is technically a megaphyll and in ferns, it is often referred to as a frond. New leaves typically expand by the unrolling of a tight spiral called a crozier or fiddlehead fern. This uncurling of the leaf is termed circinate vernation.
Fiddle Leaf Fig. The fiddle leaf fig from the ficus genus of trees is an exciting species to grow with larger leaves than the others from the genus. This indoor tree type plant grows over 15 metres tall in it's natural habitat and up to 3 metres indoors, although they can be topped to prevent them growing taller.ome of the lower leaves will naturally drop when the plant is seeing new growth to encourage new leaves to grow. One cause can be lack of water (although leaf discoloration and becoming dry should be noticeable first) or low humidity (dry air).
