The green color is associated with nature, good fortune, and financial prosperity, yet it also symbolizes envy and jealousy, as in Shakespeare’s coinage “the green-eyed monster”. With or without this symbolism in mind, many gardeners opt for green flowers to instill a natural touch to their homes.
As for care requirements, most flowering plants are killed by incorrect watering and most prefer to be given a good soaking then left to dry out. Never mist in bright sunlight since this can leave scorch marks on foliage. Some flowering plants require higher humidity. Prune old flowering plants in the spring to encourage flowering. Finally, most flowering houseplants prefer diffused daylight. Green flowers are not very common but they make wonderful flower arrangements if combined with other plants in different shades of pink or orange. Here are 40+ green-flowered species and concise instructions on how to care for them.

Why are the green flowers rare?
Greens are very rarely seen in floral arrangements and cultivation and botanists still haven’t come up with a 100 percent reliable theory. One assumption is that chlorophyll is present in petals and another is that it is the result of flowers being blue and yellow. Still, it is indisputable that green flower species are worthy of attention and research, of course.
Flowering plants often have highly ornamental evergreen leaves, so they are worth cultivating not only for their flowers, but they are doubly worthwhile. Like foliage plants, flowering indoor plants also have some basic requirements which should be met if they are to provide you with the pleasure of a superbly ornamental plant.
That’s primarily a good light – preferably direct, regular spraying or trays of evaporating water and careful pruning after flowering. With this in mind, you will be able to grow these green species, but also other types of orange and pink flowers, along with black or black-and-white species.
