Tips for Growing Long Island Native Plants

Anthony Marinello has been dedicated to growing native plants for more than 10 years. In addition to learning from independent research, coursework in permaculture and local experts, he has learned from trial and error. Here is his advice — including cautionary tales — for gardeners interested in going native.

1. “Native” isn’t always native

“Just because a plant is native to North America does not make it native to Long Island,” he warns. And a plant may be native, but still be an aggressive grower better suited to living in the wild than your front yard. It might be a heavy seeder, for instance.

“I learned that after planting cup plant (Silphium perfoliatum), a member of the sunflower family,” he said, relating a decision he soon regretted. “It was like a tentacle plant! It would die to the ground every year and regrow, and then the seeds would pop up all over the place.” Marinello recommends checking Wildflower.org or the New York Flora Atlas, newyork.plantatlas.usf.edu, to learn whether a plant is native to our area before planting it.

 

2. Learn botanical nomenclature

Gardeners should know the botanical name of the plant they are looking for to ensure it is the straight native species and not a hybrid from the nursery industry, Marinello says. “Because native perennial plants have evolved within their respective ecosystems, they’re designed to thrive in our climate and soil. They are extremely drought resistant, cold hardy, require no fertilizer, and are pest resistant, besides being highly ornamental.”

In addition, it’s not uncommon for more than one plant to share a common name. American boxwood, for example, is the industry name for a Eurasian shrub, Marinello says. And Eastern red cedar (Juniperus virginiana) is actually a juniper, not a cedar, while Northern white cedar (Thuja occidentalis) is the tree commonly called arborvitae. Although both are native, they aren’t remotely related. The only way to be certain of the plant you are getting is to check its botanical Latin name.

3. Consider butterflies and bees

“I would like to see people planting more milkweeds because they feed monarch butterflies,” Marinello says. “They thrive in wet, dry, shady or sunny conditions and provide a ton of color in the garden. It will make most of the pollinators happy in your garden — bees will be all over it, and you’ll get caterpillars and butterflies.” New England and New York asters, Virginia bluebells, goldenrod and native willows are other favorites Marinello plants to provide a food source for butterflies and bees.

4. Aim for four-season gardening

“We seem to focus more on summer plants, but it’s important that we plant early spring bloomers and late fall bloomers, too,” Marinello says. “Pollinators that emerge early in the season don’t have a lot of options for food, especially in suburban gardens.” Good spring choices include native maple trees — red maples or swamp maples — and native willows, which provide early blooms. For fall, native asters and native goldenrods are good options. In addition, oak trees house 300 types of insects that feed our native songbirds; exotic trees house maybe two or three types of insects.”
