Darling Dahlias

The title of this post comes from a charming mystery series by Susan Wittig Albert, featuring members of a ladies' garden club in Darling, Alabama, during the Great Depression. Dahlias are not a major feature of the books, just the name of the club, but today the dahlia bed at the Toledo Botanical Garden became the center of my attention for a while.

Dahlias are not plants that I have grown much (anything that requires staking, regular feeding, and digging up in the fall not being something that is likely to live long in my yard), and these beds are not the sort of garden that generally appeals to me, but some days, you have to love sheer exuberance, and that is something that dahlias have.

Where does one even begin to describe such a ridiculous explosion of a blossom? Dahlias have come a long way from the daisy-like wildflowers "discovered" in the mountains of central Mexico in the seventeenth century (though flowers similar to wild species are available to gardeners in the US). Today's dahlias come in a range of heights, shapes, and bloom sizes, from miniatures that hug the ground to plants taller than my 5'6".

This gorgeous thing is called "Spartacus."

The dahlias to which I am drawn tend to be the gaudy ones, dahlia genes allowing for a greater variety of petal shapes and flower forms than most plants. The old-fashioned daisy shapes and the two varieties above are just a few of the existing dahlia types. Some form nearly round pompoms

while others grow quilled petals

and some put their energy into making their fertile flowers the eye-catching part of the blossom. (No, those large petals that draw the human eye are not the business end of a flower, which is, after all, a sex organ. The important parts are often the tiny, inconspicuous ones.)

Looking at some of the blooms on display had me wondering how these things get pollinated. More importantly, do they do anything for pollinating insects? On many of the blossoms, nothing that resembled a stamen or a pistil is immediately observable, though the plants are obviously managing to reproduce. 

Looking closely, I did finally manage to see a few insects drawn to the plants, some tiny black things in this pale yellow giant,

something on the petals of this red collarette type,

and finally, a bee finding something to her liking.

Our cultivated dahlias are unlikely ever to be major players in a wildlife garden, but once in a while, there is something to be said for pure fun.
