Flowering…A Reason of Their Own:  A Look at Agave Flowers, Structure and Relationships

This is one of the lower umbels, the second peduncle from the bottom. The others contain more individual flowers. This umbel was caught in the stage where the filaments are collapsing and the styles extending. Nectar has spilled to many surfaces. The tepals have begun to shrivel as well. Coarse pollen grains show on the anthers with some ‘spilled’ to other surfaces. Individual flowers aren’t particularly pretty.

Flowers can be ‘incidentally’ beautiful.  We often selfishly view them as products of nature intended to fulfill our own hunger for beauty, failing to recognize them for what they are, living organic structures evolved over time to continue their own species, organs and tissues meant to attract the necessary attentions of pollinators, to produce the seed of generations to follow. We, as a society, have learned to view a select few of these as beautiful.  We respond to them in a way not unlike the pollinators themselves do, and by either ignoring them or focusing our attention upon them, we too alter their future form and their very existence.  Sometimes we do this more directly through choosing the plants we want around us.  Other times it is our indifference that seals the fate of a plant or landscape, especially when the flora is unable to grab our often preoccupied attention and we clear land for development wasting all of the ‘lesser’ weedy natives we’ve learned to undervalue, or, through our efforts to ‘improve’ plants by controlled breeding and hybridization, intentionally altering their form even the conditions under which they will grow.  Sometimes, in our desire, for fashion and an idealized beauty, we attempt to control and remove that which we don’t want, creating sterile flowers, the antithesis of what a plant would ‘want’.  We select for bloom size, scent and color, for period of bloom, we seek to increase the number of petals and alter the pattern they may be held in, even the lifespan of the individual flower, the height of the plant so that it doesn’t flop over, the ability to grow it in more sun or shade, the shape and color of leaves and the form of the whole plant.  We attempt to control all of this and crank out a uniform product that can be ‘plugged’ into landscapes and gardens as desired.  Plants with dependable performance characteristics, a pedigree.

We need to remember that this is what we ‘want’, not what the plants ‘want’, nor is it necessarily in their best interest as either a species or a member of a plant community.  These days most of ‘us’ aren’t gardeners.  Our relationships with nature were broken long ago.  It is difficult to see the critical connections in nature, between plants and the organisms they have evolved with, upon which they are dependent, especially if someone is not looking.  It is even more difficult to see where we ourselves fit into this in our materialistic, consumer society where so many of us measure ourselves and others by the things and property we own…and are quick to ‘take’ from others.  I’m going to paraphrase a snarky rejoinder I’ve heard these last several years, ‘Yeah, you’re special, just like everything else!’ and I mean this in the broadest sense.

Losing Our Urban Landscapes: Sustainable Goals and Our Crisis in Leadership

The Brooklyn switching yard. These areas must be kept clear. The fence line to the right, next to the container yard, is typical, here filled with common weeds, aggressive invasives and Tree of Heaven.

The Brooklyn switching yard. This ‘landscape’, in a modern utilitarian sense, is ideal.  These areas must be kept clear. The fence line to the right, next to the container yard, is typical, here filled with common weeds, aggressive invasives and Tree of Heaven…and it doesn’t matter.  It works and that is the priority.  Whatever results elsewhere…is not.

The following is intended as a template for action or a beginning point for a discussion that is long overdue.

Landscapes are more complex than most people realize.  They can go seriously awry in a very short time.  Undisturbed native plant communities are relatively stable and are able to respond on their own, as they have for millions of years…if the disturbances they suffer are relatively small.  Unfortunately these plant communities have been decimated in urban and most rural agricultural areas severely compromising their abilities to respond in a positive and effective manner.  The addition of invasive species to the region puts even stable, undisturbed plant communities at risk.  Because we are not all ecologists, or even gardeners, what can we realistically do to stop or reverse this process of landscape degradation?  The decline of our landscapes is linked to a long history of practices that have ignored the value of both our native and contrived landscapes, a belief in a right to ‘dispose’ of the land in whatever way we so choose and our denial that this destruction matters.  We have done this through our land management practices, our designs and the uses of the land itself even those that may seem unrelated, many that have become automatic in our society and are directly related to how we live, work and play today in the modern world.  Our active threat is inherent in the way that we do business.  Our attempts at correction are, too often, limited to only slight modifications that do not put any undue ‘pressure’ on our local economy, business or the privileges that we have come to see as ours.  We are a society that has, in short, become disconnected from the realities of life at the local level and what is required to support it.  We see a limitless nature that is there for our use.  Whatever we may need, we believe that we may merely buy from elsewhere, an elsewhere that is limitless though undefined.

To turn this situation around, or to make significant improvements, requires that we examine what we are doing now, that may be working against the goals that support life and landscape,…and stop.  We have to stop doing the things that are working to continuously disrupt the ‘healthy’ functioning of the landscape.  If we don’t do that then all of our attempts at improvement, all of our tweaking of our system, will come to nothing.  We cannot ‘save the patient’ with good thoughts while they bleed out.
