Storm Clean-Up 101: Salt-Tolerant Plants

Hibiscus syriacus 'Aphrodite'On the heels of Sonia Uyterhoeven’s informative series on post-hurricane garden recovery, Jody Payne, the Director of both our Rock Garden and the soon-to-reopen Native Plant Garden, offers a listing of hardy and salt-tolerant plants worth including in your garden or landscape. With proper planning and a solid understanding of the conditions facing these new inclusions, this supplement should put you on the path to a sturdier coastal planting–not to mention less storm season stress.

“Salt tolerance is a relative term,” Payne adds. “Some of the recommended species here would be better sited away from prevailing winds, perhaps sheltered by a building or hill. This list is meant to open ideas for which plants are salt tolerant, but choices should be further researched based on the actual conditions of your site.”

This is quite a long list, but it’s intended to show you just how wide-open your options are when it comes to planting a coastal or near-sea plot. Head below for the many tree, shrub, annual, and perennial species available, and stay tuned in the coming weeks for a follow-up from Travis Beck, the NYBG’s Landscape and Garden Projects Manager.

Have questions we haven’t answered yet? Leave them in the comments! With access to some of the finest horticultural minds in the country, if not the world, we’re more than happy to help you with your post-Sandy gardening conundrums.

    Apparently, not roses. The storm surge was about 6-7 feet deep on my street in Oceanside, although the water drained within hours. I just planted four bare root roses from j and p about a week and a half ago, and they are already dead. My existing bushes are dead or close to it, although my mini rose bush and two of my hybrid teas that had previously reverted to rootstock seem to be leafing out. So is my zephyr in drouhin (leafing out). The gardener laid seed down on the lawn, all of which is just laying there on the surface like a lox, not sprouting at all. We cannot spare $275 for soil testing. Thank you, Sandy.

    thank you for all the information. i live in far rockaway, queens and my garden was totally inundated with about 2-3 feet of water during hurricane sandy. now that things are budding, i see that a lot of my plants are coming back. the appearance of lots of dafoddils gave me hope for the rest of my garden. looks like all my peonies and tree peonies survived thank G-d. there are buds on my hydrangeas, peach trees, azaleas and most of my roses have leafed out. however, i lost a lot of my evergreen shrubs and the forsythias have just a few yellow flowers. the rhododendrons are looking really bad. i’m wondering if you know whether my perrenials will survive. i have echinecia, heuchera, liatris, asian lillies, monarda, rudbeckia, asters, daylilies, rose mallow, hostas and lots of other perennials not on your list. the weather has been a little crazy this spring so i’m wondering if the perennials are just a little late or they will not be coming back at all due to the salt water and flood.

    I live by the water on south shore of Long Island… All our Leland’s and arbivadis died due to salt damage…40-50 trees… Can u recommend an evergreen shrub and trees for privacy that are salt tolerant
    And not so expensive?

  4. Sue S says:

    My yard in Blue Point NY was covered with surge water. Storm ruined all my Blue Hollies (Ilex x meserveae), all the PJMs and rhodos. Killed all of the Leyland Cypress in far back yard & Hinoki Cypress, all of the painted fern, ajuga, all new perennials. What did recover well were the dwarf lilac, the viburnums, weigela, the upright blue spruce, beautyberry, all of the hostas, Little Bunny ornamental grass, all of the bulbs. The fothergilla & glossy abelia had tops killed but are coming back. As the storm-killed plants were big, hurricane cleanup is a big job removing dead material and filling in the gaps.

  5. my aborvitaes turned brown (approx. 20 – 30 % of each one) after sandy. they are located on long beach island. is there anything i can do to save them ? your information would be greatly appreciated. also if not what would you suggest planting for use as a privacy hedge approx 6-10′ high. Thank you so much!

  6. Bill Rambow says:

    I live on Groton Long Point in SE CT. Our arborvitae privacy hedge died after the yard was flooded.

    I am about to replant and would like a couple of options for another privacy hedge. I need about 8′ to be effective and would prefer something that is faster growing.

    Can you make any suggestions?

  7. Matt Newman says:

    Hi all. I’m gathering your questions and submitting them to some of our horticulture experts to try and get you some answers, however belatedly. Thanks for your patience!

  8. Rick Schneider says:

    If you have a narrow space try a privet hedge, deciduous but dense branching gives you privacy. It may take a few years for the results you want.

    I you have space for width growth try American Holly, Cryptomeria, Colorado Spruce and Eastern Red Cedar. All are evergreen. Salt spray is different from salt water flooding. If you had salt water flooding unfortunately all will die except American Holly which grows in Fire Island. This Holly may drop their leave but will rebound in the spring.

    Stay away from Arborvitaes, Leyland Cypress and Skip Laurels.
