Going to seed

Fireweed (Epilobium angustifolium) about the send off its abundance of seeds.

Some years ago I took a photography workshop at the New York Botanical Garden. At the end of a day spent shooting the vast array of flowers in the perennial gardens, Allen Rokach, our teacher, told us to come back next morning with two favorites to share. Everyone else brought in pictures of flowers at their crispest and dewiest. I brought in a fading iris and the seedheads of giant alliums.

Allen was forbearing, even rather fascinated by this choice. It’s not that I don’t love flowers at their freshest. But there is something about the fading flower, the seed heads, the seeds themselves that I am drawn to. This is part of the life of the flower. In fact, this is the point of the flower. While we enjoy the exquisite beauty of form, the softness of petal, colors ranging from the subtlest to the wildest of shades, the whole design is to attract pollinators, get pollinated, and produce the next generation.

So all that beauty isn’t about the joy and refreshment of our eyes. We were 100 million years from the horizon when angiosperms (fruit producing plants) first appeared. It’s likely that we owe our eventually showing up to the benefits their nutritious fruits and seeds brought to the animal kingdom. The goal of floral beauty is to create structures for seeds to develop, and to lure bees, hummingbirds, flies, beetles, bats, butterflies and other pollinators to help with the task.

Color, scent, form, and those inviting, exquisite petals signal that sugar is available. While the nectar, deep in the flower, is sipped, the anthers at the end of the flexible stamens brush pollen on their guest. It’s common in spring and summer to see bees, their legs swollen with yellow fuzz, diving drunkenly into flower after flower, dropping some pollen off, picking up more.

At each flower, the pollen brushes off the carrier onto the stigma, the top of the tiny stalk (the style, barely visible above) nestled in the center of the stamens. The pollen’s DNA information then proceeds to the ovary at the base of the flower. The ovary, often still small when the petals fall, like the columbine above, swells into fruit as the seed matures. Eventually the ripened, swollen fruits begin to dry and split open, emptying their abundance of seeds.

SeedheadsThe abundance can be staggering. That long curve of fluffy seeds in the fireweed at the top of the post is from one flower, on a stalk containing dozens of flowers, among millions of fireweed stalks.

Seeds must then move from pod to receptive ground. In the case of harvesting fruits and seeds for eating, farming or gardening, we have a huge role to play in this, and a minor role, which we share with our dogs and other local fauna, in carrying sticky seeds from place to place on our pants and socks. Other seeds simply fall at the feet of the flower stalk. Not content to wait for creatures to walk by, many seeds are attached to feathery filaments that allow the wind to disperse them.

All of this can be going on at the same time. The desert creosote above has a fresh flower, with its anthers full of pollen, a fruit at the top, and two stages of open pods: one with the seed filaments just emerging from the dried and split fruit, and one beginning to disseminate its feathery seeds.

I like the tossed-aside-lingerie look of fading flowers, but it’s the pods, or seedheads — sculptural, often a bit wacky, with dried-in-place curves and unexpected twists — that I particularly like.  I love the way the designed-for-wind filaments catch the light before they fly off, and the increasing translucency of some pods as they dry.

Loving flowers takes a certain existential fortitude. They are a fleeting lot. This is especially true of wildflowers. In a garden, you can create bloom all season, all year in warm climates. You can make space for wildflowers, and even plant them, but you have very little control over what they do and where they go. This is why cultivars — flowers bred for particular traits — are so important to the garden industry. They are tamed wildflowers.

The truly wild ones come and go on their own tens-of-millions-of-years-old schedules. If it’s too dry, too cold, too wet, they may choose dormancy. If all is right, they will grow riotously. If there’s too much competition from invasive plants, they will bide their time, the seeds remaining dormant for years. Once they bloom, they slow or speed up their flowering and fading according to the weather.

While they’re blooming, I don’t think much about all this. I just want to see them. It’s when they fade and the pods ripen that I remember that they’re not here for me. The seedheads remind me that we are part of their history, not the other way around. We have taken full advantage of this process to grow food, harvest seeds, enjoy gardens. But it’s not a cycle for us. It’s a cycle we fit into. Watching this ancient unfolding roots me in the history of the earth, in the forces that, with slow and infinite care, brought us here, blessed with the ability to see and love beauty.
