Elle Fanning wears a VERY racy number comprising metallic nipple pasties and silver feathers for a night out in Cannes Violets are the sole larval food source for fritillary butterflies. In the book The Living Landscapeby Rick Darke and Doug Tallamy, Tallamy writes: “Plants such as the common blue violet ( Viola sororia), long dismissed by gardeners as a weed, can be reconstituted as desirable components of the herbaceous layer when their ecosystem functionality is re-evaluated. That being said, there is a defense for violas. People who find violas to be a troublesome lawn weed – expanding far and wide to the exclusion of turfgrass – have these hidden flowers to blame. Seeds produced in these hidden flowers are generally superior and more abundant compared to those produced by their showy counterparts. Some are also carried away by ants and dispersed to new locations. The fruits they form split open when mature and deposit their seeds directly below the parent plant. The cleistogamous flowers of violas generally appear in the summer or fall, after the chasmogamous flowers have done their thing. A good strategy is a mixture of both cross- and self-pollination – a strategy that violas employ. This isn’t necessarily bad, at least in the short term, but it has its downsides. There will be no mixing of genes with other individuals. A downside, of course, is that a seed produced via self-pollination is essentially a clone of the parent plant. All this effort is worth it when it results in the ample production of viable seeds, but what if it doesn’t? Having a method for self-pollination ensures that reproduction will proceed in the absence of pollinators or in the event that floral visitors don’t get the job done. Colorful petals, nectar, nutritious pollen, and other features that help advertise to potential pollinators all require significant resources. Perhaps as a way to ensure reproduction, violas also produce cleistogamous flowers, buried below their leaves.Īn illustration of the cleistogamous flower of Viola sylvatica opened to reveal its sex parts - via wikimedia commonsįlowers are expensive things to make, especially when the goal is to attract pollinators. Cross-pollination occurs in these flowers, and seed-bearing fruits are the result. They are the familiar five-petaled flowers raised up on slender stalks above the green foliage. They open and expose their sex parts in order to allow for cross-pollination (self-pollination can also occur in such flowers). Most of the flowers we are familiar with are chasmogamous. The opposite of cleistogamy is chasmogamy (open marriage). They are a secret only because unless you know to look for them, you would have no idea they were there at all.Ĭleistogamy means closed marriage, and it describes a self-pollinating flower whose petals remain sealed shut. That’s the story behind the cleistogamous flowers of violas. If pollinators are unnecessary, there is no reason for showy flowers, or to even show your flowers at all. Showy flowers are showy for the sole purpose of attracting pollinators. There isn’t a reason to show it off, after all. I suppose it’s not a secret really, just something out of sight. Sometimes they even bury it shallowly in the soil near their roots. Violas keep a secret hidden below their foliage. ![]()
