Window Boxes Stretch the Season

I’M SHOWING YOU the window box, above, one of two attached to the front windows of my rental apartment in Prospect Heights, Brooklyn, not because I’m so very proud of it — they’re rather pedestrian, not to mention lopsided, but out of some documentary compulsion.

If you recall, this is what I started with in early May, below: pale white/lavender pansies, which I knew I’d have to replace in high summer, an interesting twisted juncus, vinca and bacopia vines, a hosta, and some angelina sedum. That, and high hopes.

As it happened, I did what I could on the fly on to keep them up on the infrequent occasions this summer when I spent time in Brooklyn. I had the help of my landlords, who kindly watered. I grabbed fill-in plants at the nearest hardware store, which turned out to be pink-red impatiens and begonias. I’ve done better in summers where I’ve actually been there to coddle, feed, and water, once even inspiring an entire block to follow suit.

Left to their own devices, the impatiens took over, the angelina sedum disappeared (not enough sun), and the bacopia and vinca drastically need cutting back. When I get back to Brooklyn tomorrow after more than a week away, who knows what I’ll find…but I think I’ll pick up a few mums or ornamental cabbages on my way to extend the season even further. After all, that’s what they sell those things for.

My Arty Brooklyn Window Boxes

After a week

ABOUT A WEEK AGO, I PLANTED UP the two boxes attached to the front windows of my garden-level apartment in Prospect Heights, Brooklyn, and I’m pleased with how they turned out.

I had planned to shop a local plant sale, but couldn’t wait: I ended up going to Lowe’s “just to see” what they had, and buying everything I needed there, a monochrome mix (white flowers only) of perennials and annuals.

The centerpiece of each box is a plant I’d never seen before: Juncus effusus or ‘Big Twister Rush,’ a perennial ornamental grass with some straight shoots and some corkscrew ones. They’re real eye-catchers. Here’s what else is in each box:

• Variegated hostas (‘Minuteman’ in one, ‘Wide Brim” in the other)
• Chartreuse Sedum ‘Angelina,’ for textural variation
• Pansies – white with a touch of purple
• Bacopa, with tiny white flowers which will trail
• Variegated vinca, another trailing vine

That’s it, except for stuffing a white impatiens into one corner that looked empty. The pansies will last until July or so (they’re cool-season annuals), and then I’ll replace them with something else. I re-used the old potting soil that was in the boxes, topped up with some fresh, and mulched everything after planting to keep things moist. They’ll need daily watering when it gets hot, and I admit to using a weak solution of Miracle-Gro in my city containers.

Cost of each box: about $25.

Upon first planting

GARDEN VOYEUR: Foolproof Plants for Brooklyn Backyards

THIS IS WHERE I cut my gardening teeth: the 21’x35′ backyard on Verandah Place in Cobble Hill where we lived for twenty years, above, as it looked in May/ June.

We inherited a graceful Japanese maple, a stand of honeysuckle (abelia ‘Francis Mason,’ I later learned), and climbing hydrangea that served to disguise a rusted chain-link fence. There were a few slabs of slate on the ground, which we gradually expanded to a good-sized patio, with pieces salvaged from vacant lots in Red Hook and contributions from friends (I remember one summer night being surprised by a delivery of bluestone slabs from a friend who saw them going begging someplace).

We added a small wrought iron balcony and steps going down into the garden from the parlor floor, and had some old-school masons build steps and a landing with bricks and railroad ties — nothing elaborate — leading down to the well area.

Little by little, through trial and error, I learned how to create a garden. The main challenge: excessive shade. Though south-facing, sun was limited by gargantuan ailanthus trees in the neighboring yards.

A couple of the principles that served me well:

• Use variegated foliage – that is, shade-tolerant plants that don’t flower showily but have green and white foliage to bring light to dark corners of the garden, e.g. ‘striped’ hosta, caladium bulbs, variegated lirope (the festive-looking silver stuff in the left foreground below), vinca and ivy – anything at all that comes ‘variegated.’

Below: The white feathery plumes on the right (there’s a purple one too) are astilbe — shade-tolerant, reliable, ironclad.

• 

• Limit color for cohesiveness. I stuck to a palette of blue, purple, pink and white. Very little orange, red or yellow, a situation partially dictated by circumstances; most hot-colored flowers require a lot of sun.

Most satisfying: oak leaf hydrangea along the back line of the property. Three plants (expensive at the time; about $50 each) grew in a couple of years to create three-season glory, with huge, neat, colorful leaves and massive white panicles from June until frost.

See below for more plant suggestions. Any and all of these are recommended for Brooklyn backyards; they’re foolproof and readily available.

Below, left to right: chartreuse andromeda, Japanese fern, ‘money plant’ (those purplish flowers will turn to dry, translucent, coin-like things come fall), the blue spikes of ajuga, all under a climbing hydrangea, soon to flower white.

Below, a deep shade corner, with (left to right) the round glossy leaves of European ginger, Japanese fern, small leaved ivy and small-leaved chartreuse hosta, and yellow-tipped houtonia — pretty, with white flowers, but invasive — you have to be prepared to pull it out where you don’t want it.  The cardboard is from a package of caladiums, to remind me where I planted them (they don’t show up till July).

Below, my favorite afternoon reading spot. Left to right: pink creeping phlox; white ‘starry eyes,’ a sun-loving groundcover; the remainder of some pink bleeding heart (easy, showy, great for shade); small white flowering bulbs (the name escapes me  – anyone?); variegated hosta; blue wood hyacinth in the background.

This last picture, below, is a bit earlier in the season — late April. The hostas are just coming in. The fuchsia azalea was too gaudy for me; I got rid of it. In the foreground, you can see brownish huechera (coral bells), more ‘starry eyes,’ yellow-flowering lamium or dead nettle, and some tiny hybrid tulips on long thin stems — ordered early on from a bulb catalogue, they came back year after year, providing great pleasure.

Mind you, these are all perennials, not annuals. They don’t flower all season, just for a few weeks. But you plant them once and have them for years with no additional effort or expense. Perennials are the way to go if you’ll be staying put for any length of time. You can divide them in spring or fall to create more of the same, and take some with you if you move.
