What is a Species?

Specious (?) Speculations on Species 

IMG_8181.jpg

Iris x pacifica ‘Tanus’.  This is a hybrid Iris of species know collectively as series ‘californicae’, a group of Iris endemic to the Pacific coast of the US, primarily California, some very localized, with several occurring north through Oregon, and one, I. tenax, all of the way to the Puget Sound area of Washington.  These species obviously can be crossed.  Their form shows the distinctive tri-partite structure of a classic Monocot, in Genus Iris taking this particular form with 3 ‘falls’, 3 stamen and stigma structures angling out from the ovary at center, across the brightly colored ‘signal’ on each fall and the 3 more upright ‘standards’.

I do not recall from high school biology how an individual species was defined to us in our text or class, nor do I in my college Zoology 200 series.  All that I have is a general understanding that it is a select population with a shared, narrow, range of physical characteristics, in the case of plants, best determined by their floral or reproductive parts, that is able to reproduce stable offspring with the same range of characteristics.  Webster’s defines species as:

“a category of biological classification ranking immediately below the genus or subgenus, comprising related organisms or populations potentially capable of interbreeding, and being designated by a binomial that consists of the name of a genus followed by a Latin or latinized uncapitalized noun or adjective agreeing grammatically with the genus name” Continue reading

I hope that you will forgive me this departure into verse, prose, whatever this is…another thread in my life.  I don’t think it is too far amiss, because, after all, horticulture is the ‘art’ and science of growing plants.  Originally I began this as an idea for a children’s story, yes I did, the life of a particular Dandelion, but, probably due to my more recent reading on topics like photosynthesis, cellular metabolism and a biophysics response to the question of, ‘What is life?’…it has morphed…considerably.  When you read this, keep in mind that my intention was to write from the perspective of the Dandelion, a concept pretty incomprehensible to a modern American. 

The Taraxacum Cycle

Stories all begin with a single word, a seed, around which they grow, nurtured over time by the things we all share in common, family, history and experience.  They contain ‘truth’, but are not themselves true, because they must be told in such a way that they lure the reader in and are ‘believable’.  They are organic and grow within us and to the extent that they reflect our own ‘story’, that they meet our expectations, we stay with them and them with us, because there is no story if it is forgotten.  So, the author must manipulate what he knows, he must ‘lie’, to bring you in and keep you, weave truth and lie into a whole.  We take the stories you already know and introduce our own characters, set them in exotic though familiar settings, and, if a writer is good, introduce enough, but not too much, that is ‘new’, different from your cultural experience, your expectation, that you are affected by its unfolding, that you become a part of the story and look at your world in a different way, even if only a little bit.  The word here is Taraxacum.

The Strength to Stand: Surviving the Load of Ice and Snow in Portland

img_7484

The morning after the big snow along the front of my house. To the left, splayed out and weighted down, is my Butia capitata. This one, from Argentina and not used to snow, had me worried, but it sprung back. The Oleander to the right, next to the sign, was bent down to the ground from its 8’+. Further back is one of my Chinese Windmill Palms, Trachycarpus fortuneii, bent under a snow load it is used to from high in the mountains of southern China.

Many of us who garden in the Pacific Northwest, and especially those of us in Portland this year, will be visiting our garden centers and favorite nurseries this spring and summer with a little more anxiety and need as we look for plants to replace those that have succumbed to this winter’s cold, ice and snow loads, all of which were more severe than what we have come to expect here.  But before we pull on our boots and don our rain gear to head off for shopping there are several questions that we need to consider before we make our purchases.  Not all of us draw up plant lists, but most of us at least carry in our heads a wish list of plants we have seen in other gardens, in magazine spreads and while on vacations, but if we want to avoid some major mistakes and move our gardens toward the kind of landscapes that we really want, we are going to have to put on our reality goggles and critically assess our choices…that is, if we want to avoid unnecessary losses in the future.
