Due to the overwhelming response to the original installment of "How peculiar," I have put together a list of beautiful green-flowering cultivars of some favorite plants. Even if a name implies the flower is a true green, some are actually pale yellow while others are just dull-looking. You can be the judge of these green cultivars.
Peony 'Green Halo'
The stunner at right is Peony 'Green Halo.' It might cost you an arm and a leg as some other interesting peony cultivars do, but it will definitely stop people dead in their tracks. Blossoms have a stark white, slightly raised center trimmed by spring green petals and as they unfurl, the blooms showcase bright yellow stamens and more of the unusual green petals. 'Green Halo' needs no different care than any other peony and is hardy in zones 3 through 8.
It seems like irises come in every imaginable color, from black to blue to yellow. But did you know there are several available to cure your need for green? Cultivars like 'Olive Garden', 'Green Wave' and 'Green Jungle' are three that exhibit unique, if not acquired tastes, of green.
' Green Jungle'
Just like irises, the color spectrum of daylilies seems endless. Fortunately, (or unfortunately, however you look at it) you could have a specialized habit of collecting green daylilies within your bigger addiction! Daylily greens seem less predictable and range from pale yellow to shocking green throats. 'Green Eyes', 'Green Halo' and 'Green Quest' are some other greens to check out.
'Green Morning Glow'
The 'Green Rose' (Rosa chinensis var. viridiflora)
Each 'Green Rose' seems to have an interesting story all its own. Stories of family heirloom 'Green Roses' being passed from one generation to the next abound in its entry in the PlantFiles. Besides the interesting stories that each specimen carries, the rose itself has a very unique history. The rose was discovered as a mutation of a China rose prior to 1856 and little else is known about its beginnings. As Paul Barden of Old Garden Roses and Beyond puts it, it's like the China 'Green Rose' forgot to make petals so it made the bloom up of sepals. That's right, it's not actually a green bloom in the traditional sense, it is actually a grouping of sepals that make a pretty striking "flower." It is reliably hardy in zones 6 to 10 and will definitely make a statement in any garden .
Yes, there are even green flowers available for an early spring fix! This charming beauty to the left is Tulipa viridiflora 'Spring Green.' Some other green tulips to look into are 'Green Wave', 'Green Village' and 'Groenland' (pictured below).
Primula 'Green Lace'
This hardy primula is a green knock out. Perennial in zones 4 through 9, 'Green Lace' needs partial to full shade and will tolerate a bit of water. Its blooms are strikingly ruffled with bright yellow centers which fade to shamrock green. If you wanted a novelty shade garden, 'Green Lace' might look interesting next to Heuchera 'Green Spice' and a chartreuse hosta such as 'June.'
If you don't live in a warm enough climate to grow amaryllis outside (zones 8 and above), then Amaryllis 'Evergreen' would be a treat to grow inside as well. Its spider-like blooms are made up of delicate pale green petals that are shockingly different from your average warm-hued Amaryllis. This cultivar might be a little harder to get your hands on, but it would be well worth the covetous effort.
Nicotiana 'Lime Green'
For fast and prolonged color, try this green blooming annual. 'Lime Green's' blooms range in color from pale yellow to bright limey green. It needs full sun though it will tolerate some shade and will grow up to 4 feet tall. For added character, its flowers are fragrant and the leaves are fuzzy as are most flowering tobaccos.
Firecracker Plant 'Green Ice'
Pictured at left, this unusual Crossandra has light bluish-green flowers. It is a tropical and is only hardy in zones 10 and 11. Its shiny green, substantial leaves provide a nice contrast to the soft, cool tone of the blooms. Outside it can grow up to 3 feet tall; however it can make a good houseplant as well. You heard me right, you can have green flowers indoors as well!
Crown of Thorns 'Forever Green'
By any other description, this is a run-of-the-mill Crown of Thorns. That is, until it blooms. This euphorbia blooms pale green flowers amid small leathery leaves and spiked, gray stems, which makes for an interesting contrast. It is a hardy in zones 9 and 10, but can function as a potted outdoor plant if it is not overwatered and is brought inside for winter. 'Forever Green' would definitely be a conversation piece in your collection.
Thanks to PlantFiles contributors for all the beautiful green flowers!
