Helen Chesnut's Garden Notes: Sunflowers are useful as well as beautiful

The flowers attract pollinators and other beneficial insects, and they come in an almost-overwhelming number of varieties.

Like most gardeners I know, I’m fond of sunflowers. That’s why I paid special attention to a radio interview with a flower farm owner who was expressing acute delight in her summer crop of cut sunflowers. I took note of her advice: Plant sunflowers close together, between 10 and 12.5 centimetres apart.

Most sources recommend that spacing only for the dwarf varieties, and a minimum 60-cm spacing for the giants.

The grower’s advice turned my thoughts to a long row of sunflowers growing just a block away from my home. I’d been admiring the unusual planting all summer, as the plants developed, flowered, and produced seed heads of various sizes. By mid-October those seed heads had taken on a drooping posture.

The sunflowers grew on a narrow length of ground that sloped gently down to the street, in front of a property’s south-facing side fence.

Seeds had been planted in a series of indented circles, each 50 to 60 cm across, arranged 120 to 180 cm apart. Six to eight plants grew in most of the circles, with no apparent spacing between them. The largest seed heads developed from a circle with just two, thick-stalked sunflower plants. I’d never seen sunflowers grown in this way. It’s a testament to innovation in gardening.

I’m always bedazzled, and sometimes overwhelmed, by the numbers of sunflower varieties. Johnny’s Selected Seeds, a cut flower specialist, lists six pages of them. A broad diversity in size, plant habit and flower colour is just one of the sunflower’s assets. The plants and flowers are useful as well as beautiful.

The flowers attract pollinators and other beneficial insects. West Coast Seeds recommends inter-planting sunflowers with squash plants, to increase pollination in the squash flowers. Sunflower plantings have been used in places like Chernobyl and Fukushima to remediate soils that have become polluted with toxins.

Rosemary strategy. It’s always intriguing to discover different ways of growing and using plants. On the walk home from taking a close look at the sunflower planting, I visited a neighbour’s garden where I’d been admiring an unusual rosemary bush that was strategically placed at a tight house corner next to a narrow path.

The rosemary had been trained to a single trunk that separated into three upright branches at around 25 cm from the ground. Because of the tight spacing, the sides were kept cut back to allow free passage around the corner and along the narrow side path. The result: a wall of young, soft, aromatic foliage that releases its fresh scent at each passing.

Situating plants with fragrant foliage along pathway edges ensures the pleasure of perfuming each stroll beside them. A curved row of Provence lavender edging a much-used path in my garden provides that delight in my garden.
