Lantana Produces Two-Tone Colorful Blooms Available in white, yellow, orange, pink and red, the flowers of the lantana often appear two-tone as they open from buds of different hues.
Double-flower forms often arise when some or all of the stamens in a flower are replaced by petals. These types of mutations, where one organ in a developing organism is replaced with another, are known as homeotic mutations.
Bicolor blooms come in a myriad of types and in almost every color under the rainbow. They can sport an eye that contrasts to the petal edges, stripes, one color grading into another or a petal edge that contrasts with the main flower color, just to name a few.
Semi-double flowering plants have two to three times more petals than typical single flowers, but not quite as many as double blooms – generally in two or three rows. Unlike many varieties of double flowers, semi-double petals allow you to see the center of the plant.
While many flowers get their colors from either anthocyanins or carotenoids, there are some that can get their colors from a combination of both.
The term, "variegated" is applied to a flower or, more often, a leaf that has more than one color. Most often, it will be two-toned (that is, bi-colored). Often this will mean the foliage is blotched, striped, or bordered with a lighter color than that on the rest of it (or vice versa).
Dahlia. The dahlia is one of the lushest and most vibrant flowers you'll find, available in a rainbow of colors ranging from pink and red to orange or white. Some dahlia petals even have stunning color gradients, like bright reds that gradually fade into soft whites or gorgeous purples that lighten from stem to tip.
Double Tulips
Also called 'peony' tulips because of their shapes, their elegant flowers can be as wide as 10 inches (25cm). Sensitive to rain or wind, they will do well in a sheltered spot. Their average size is between 12 - 16 in.
The pink to white bell-like flowers are nodding and are born in pairs on short, thin Y-shaped stalks, seldom exceeding six inches in height, hence the common name “twinflower”. The flowers are highly fragrant and last about seven days, typically appearing in June or July.
We see double flowers in common plants including roses, peonies, carnations, anemones, camelias, and many others. A favorite I've had in my garden for years are double echinacea (coneflowers), bred both for their double blooms, and deep, rich jewel tones, much different than the pinks found in nature.
Bicoloured flowers are most common in plants that have been highly bred such as camellias, dahlias, roses and tulips.
Did you know that blue is the rarest flower color? Brandon George, graduate student in Public Garden Leadership at Cornell University, takes an in-depth talk on the color blue, why it is so rare in the plant world, and some tips for displaying it in a garden.
Twinflower Linnaea Borealis
Although mostly found in North East Scotland, the twinflower population has become critically scarce.
A hybrid plant is the result of cross pollinating two different plant varieties and growing the seed the mix produces. The plant that grows from that seed combination is called a hybrid. Commercial cross planting is done to get some type of valued attribute of each initial variety into the offspring.
Double Flower Forms
This form is by far the most popular flower form. All the stamens and carpels are mostly transformed into wide decorative petals. Unfortunately, the dense mass of petals capture the rain and become burdened with the extra weight and fall over.
Bloom number and color of petals
Single: a bloom with four to eight petals. Advertisement. Semi-double: a bloom, still showing stamens, that has between nine and 16 petals. Double: a bloom with between 17 and 25 petals. The 'Playgirl' rose has a single bloom, with four to eight petals.
Flowers, which comprises both male and female parts are known as complete or bisexual flowers. Lily, sunflower and tulips are examples of bisexual flowers. Flowers, which contain any one reproductive organ, either the male or female reproductive organs are called incomplete or unisexual flowers.
It's not terribly uncommon. Some horticulturists say it's about the same frequency as human twin births.
The flowering plants which show hermaphroditism are known as hermaphrodite flowers. They are also known as perfect or bisexual flowers. Common examples of hermaphroditic flowers are roses, lilies, mangoes, daffodil, petunia, etc. These plants can undergo self-pollination, and are not dependent on pollinators.
Incredibly romantic and beautiful, Double Daffodils resemble peonies or carnations more than classic daffodils with their packed rows of petals and all their frills. This group includes either daffodils with a doubled trumpet or daffodils with a double row of petals or even both. Many cultivars are sweetly fragrant.
Striped Tulips
These tulips are known for their streaked, or striped, multicolored petals that offer a unique and unexpected twist – associated with fascination and a sense of individuality. One of the most popular striped tulip varieties is the Rembrandt, named after the famous Dutch painter.
The Middlemist Red is considered the rarest flower in the world. It is found in London and New Zealand, with only one specimen in each location. It used to be native to Asia but is now extinct on the continent. John Middlemist was responsible for bringing the flower to London in 1804.
The Middlemist Red flower is probably the rarest flower in the world, and it can only be found in London and New Zealand. The Chinese botanist John Middlemist brought this plant to London in 1804. The flower, formerly thought to have disappeared from London, is no longer present in Asia.
