The funny little plant growing in the leafy litter under the Douglas fir turned out to be an orchid, Spiranthes cernua, nodding lady’s tresses. These are fairly tough little (6-8" tall) late summer and fall flowering orchids, and considered fairly easy to grow. A similar species, slender lady’s tresses, grows on the Phactor’s prairie study site. The genus name comes from the spiral organization of the flowers on the inflorescence (spiro- spiral, anthes – flowers).
So how did it get to our garden in a city’s center? Orchids have absolutely minute seeds, dust seeds, and plants with such tiny seeds usually make large numbers of them. Other species of lady’s tresses are known to produce 2000-3000 seeds per tiny fruit and you can judge from the number of flowers how many fruits there may be. Wind dispersal can deposit such seeds a long ways from their origin, and most will lose the land-in-a-good-place lottery. Fortunately for us, a seed found its way to our bit of nature. Now if the stinking rodents stay away, our new resident will enjoy a long and hopefully productive life.
