Best Garden Centers on Long Island NY: Top Plant Nurseries & Garden Shops (2026 Guide)

Big-box garden aisles are fine for a bag of potting mix, but when a project matters, Island gardeners make the top 10 best list below. These independents earn their loyal followings with knowledgeable staff, quality plant material, and stock actually suited to our zone 7b conditions. Here is where we send friends — from our Manhasset base down the road to the East End.

Nassau County Favorites

Atlantic Nursery & Garden Shop (Freeport). The 516 area code classic, rated 4.6 stars by nearly 300 reviewers. Family-run and open year round for every project, with a senior discount and helpful staff who take time to explain what will actually survive your yard’s sun and wind.

Fantastic Gardens. The indoor plant people. If your weakness is succulents, echeveria, and rare houseplant finds refreshed weekly, this is your spot — and their outdoor plants cover shrubs and perennial basics too.

Suffolk County Standouts

Olsen’s Nursery (Nesconset, NY). Since 1962 — a genuine Island institution on Lake Avenue South. Enormous variety, local deliveries Monday through Saturday, and the confident motto “You need it, we have it!”

The Shed Inc. Family owned and operated since 1997, this complete nursery covers trees, shrubs, flowers, tools, stone, and gravel — plus a propane filling station. Their design team helps with larger landscaping jobs.

Better Gro Garden Center (Lindenhurst). Over 30 years family-run, with quality plants year round and holiday decor from Christmas to the Fourth of July. Expert, friendly staff match plants to your location and light.

Decorative Gardens Nursery (Calverton). The East End’s resource for nursery stock and garden supplies, including deer-solution products every suburban gardener eventually needs. Their on-site production keeps prices honest and the supply fresh.

Hampton Nursery & Landscape. East End trees and shrubs with professional landscape service attached — handy when the project exceeds the weekend.

The Gallery. A smaller local gem with a curated feel — good for seasonal color and gifts alongside the usual greenhouse stock.

A Note for Pros

Two wholesale operations serve the trade rather than walk-ins: Atlantic Nurseries in Dix Hills (over 50 years supplying professionals) and Emma’s Garden, run by the third-generation Keil family. Landscapers can establish accounts for delivery across the metro area.

How to Choose

Chase quality over price alone: a slightly costlier, well-grown shrub outperforms a bargain plant that limps through its first New York winter. Check seasonal hours before you go — several places operate reduced schedules after October — and call ahead for large trees. Browse the nearby Yelp reviews for the latest word on stock, then support the family businesses that keep horticultural expertise in your town. Ready to plant what you bring home? Our zone 7b planting calendar tells you exactly when.

Frequently Asked Questions

What is the largest nursery on Long Island?

Olsen’s in Nesconset and the Dix Hills wholesale operation move the most plant volume; for retail variety, Olsen’s is the popular pick.

Do any Island nurseries deliver?

Yes — Olsen’s offers local delivery Monday to Saturday, and most landscape-attached nurseries will deliver trees they plant for you.

Where can I buy native plants?

Several of the centers above stock natives; ask for their native section — availability is seasonal and sells out fast.

Do these nurseries run seasonal sales?

Yes — most clear perennial stock in late October and holiday greenery in December; the fall sales are the best-kept secrets on the Island, so call ahead.

Can I start an herb garden from nursery plants?

Absolutely — centers stock herb six-packs from April, and staff highly recommend starting with rosemary, thyme, and chives, the three that reliably overwinter here.

Can these stores handle special orders?

Yes — wholesale houses accept special orders for future jobs, and most retail shops will locate unusual varieties if you ask a week ahead.
