When I first stated gardening for pleasure, as opposed to
being forced as a child to weed in a vegetable garden I had little to no
interest in, it was on a high piece of land in Bridgehampton belonging to my
parents. No one else in my family had any interest in gardening, even the afore
mentioned vegetable garden had been a rank failure, a fenced in rectangle of
chest-high weeds hiding renegade foot-long zucchini. There had been, back in
the days of the dreaded vegetable garden patch, a gardening book that my father
owned that captured my interest. Titled Gardening by the Sea and written by
Daniel Foley it was first published in 1965 and then reprinted in 1982. Dad
actually had both copies, but I had relieved him of his reprint years before I
knocked the pegs into the ground to square out the rough border of my soon to
be own plot.
I’m not sure why my father owned the books, possibly to help
choose which trees to plant at our old house on Hedges Land in Sagaponack,
where, when we bought our twelve acres, the ocean was visible across empty
potato fields that now grow nothing except huge, shingled, second homes. The
winds there tasted like salt all year long, so maybe he was being practical and
researching his choices, or perhaps, like me, he bought books to dream about
the possible future.
I read that book cover to cover, a couple of times, before I
ever begin to really garden in earnest. And I still get it down and flip
through it whenever I’m asked to create or consult on a seaside garden for
someone now.
The photos are in black and white, the Russian olive (now an
illegal and invasive plant) is raved about not only for it’s resiliency but
also it’s beauty, and there’s no real mention of deer resistance, but I still
love this book. It’s where I first learned to appreciate bayberry and the fact
that trumpet vine can survive on the ocean-facing front of a house. The book
talked about how hard it was to find beach plum, an issue we no longer face
with all the amazing nurseries we have out here on the East End, and it introduced
me to clethra and its ability to tolerate wet feet.
I didn’t really have to worry about salt spray in my first
garden. As I weeded I could still see that silver sliver across the fields and
past a pond, but them my parents put up hedges and the view died away. I only
grew flowers, so none of the book’s relentless knowledge of tough trees and
shrubs that could survive a winter at the beach was really necessary, but it’s
how I learned that ilex crenata was not as good with salt spray as ilex glabra,
and got my first exposure to some of the plants I now love to use -- viburnums,
spireas, weigelas and roses.
It didn’t reference boxwood, nor did it mention crape
myrtles, both plants I truly adore, but it fueled my imagination and started my
plant education. I tell people who are interested in learning how to garden out
here to buy this book, and to supplement it with Theodore James Jr.’s book
published in 1995 titled Seaside Gardening. That book’s color photos are a
little dated now, but the peek you get into local homes is deliciously
tempting. There on page 112 is their list of deer resistant perennials, which
with a few obvious exceptions (Shasta daisies, astilbe, echinacea) is not too
bad.
As a gardener, I quickly became seduced by the gardens and
garden books of the English, and still bring home random primroses, campanulas
and other fluffy, frail, fragile things even now, things that I know will,
eventually, succumb to the winter winds that whip through my garden each year.
I should knock it off and go back to my basics, back to planting the plants
Theodore and Daniel taught me all those years ago. But then I think, we’ll I’m
not close enough to the ocean to benefit from how the salt mist battles black
spot, so I’m probably far enough away to have a hornbeam, a Korean hornbeam at
that. It’s a problem.
So let’s get down to the basics of salt and salt tolerance.
First there are very few things that can handle having their feet in salt
water. Baccharis halimiflora, (groundsel) grows on the beach edge of Sagg Pond
so it certainly can tolerate more salt then anything else. Myrica pensylvanica
(bayberry) also grows down on the beach, as does prunus maritime (beach plum)
and all three are natives, but the rugosa rose that grows in the dunes is,
contrary to popular belief, not indigeous, but is a Japanese plant. I think it’s
amazings how it throws itself into the dunes facing the ocean, so I adore it.
This is the same place you find chrysanthemum nipponicum (Montauk daisy) and
the lathyrus maritimus (beach pea) which
has been successful propagated by a local grower and is available this year at
nurseries for the first time in ages. Go Jim Glover.
Last year we rebuilt a garden
in the dunes and planted both ammophila breviligulata (beach grass) and elymus
arenarius (blue lyme grass.) The elymus proved to be so successful it’s
outrunning all its boundaries. This is also a garden where the next two plants
facing the sea are Endless Summer hydrangeas and behind them juniperus
chinensis ‘Torulosa’ (Hollywood juniper.) Both made it through this winter like
champions. As did the locust trees that sat with their roots under a foot of
water at another beach front location where I work. Those trees sat in slat
water for a week after hurricane Sandy. It was interesting to see what survived
that storm and what didn’t – who would have thought blue spruce would be okay
after sitting in hurricane water in Sag Harbor? If they had just been planted
that spring, there’d be no way, but these established beauties made it fine.
That hurricane killed
spreading junipers but not Hollywood junipers, that were both terribly old in
some places while in other spots, younger spreaders survived, so there are no
hard and firm rules to be made. I’ve had crape myrtles survive beautifully inmost
locales I’ve placed them, but at my house last year three were struck back to
rootstock. So who knows? Of course we know that pinus thumbergiana (Japanese
black pine) is the most tolerant evergreen of all, but we also know that the turpentine
beetles that attack it can be devastating. Of course, if you keep all your
black pines healthy and well cared for --watered and fed -- and make sure you
have someone come check for and treat beetle damage, they will last
significantly longer. Picea glauca (white spruce) do well in dune conditions
but look a little out of place to my eye, I prefer pinus rigida (pitch pine) –
it’s a little harder to find, but much more natural looking. However there’s a
Japanese garden on the north side of a seafront house in Bridgehampton that’s
doing super well, so I think the key is to be well versed in knowledge and then
to a take a wander around your neighborhood and see what’s working and what
isn’t, and then possibly, take a few chances and try some things out.
Attached is a list of salt
tolerant trees and shrubs to get you started on your garden by the sea,
although I strongly advise trying to dig up both of these books before you
start planning or planting.
