What Kurt Weiss Greenhouses Inc. does

Kurt Weiss Greenhouses Inc. is a family-owned ornamental plant producer incorporated in New York in 1960 and headquartered at 95 Main St., Center Moriches, on eastern Long Island. The company traces its horticultural roots to Otto Muller's greenhouse operations established in Queens around 1900, and has since been controlled by four to five generations of the Weiss family. It grows and ships a broad portfolio of ornamental plants — including hydrangeas, azaleas, poinsettias, foliage plants, flowering potted plants, bedding plants, perennials, annuals, and mixed combination planters — and is self-identified as one of the leading U.S. producers of hydrangeas and azaleas and the fourth largest U.S. grower overall.

The underlying operation is controlled-environment greenhouse agriculture, with over 1 million square feet of production area distributed across multiple east coast facilities (historically 18 locations spanning six states plus Canada) and a workforce of 1,200+ employees including an international internship pipeline from 40+ countries. In-house grower teams select plant genetics globally and manage propagation, with branded sub-collections such as Hydrangeas.com, Magical Hydrangeas®, Ace of Hearts Anthurium, The Basil Tree, Succulent Society, and Patio Paradise providing consumer-facing differentiation.

Revenue is generated predominantly through a wholesale B2B channel serving florists, nurseries, landscape professionals, interior plantscapers, and architects/designers via two Long Island pick-up centers (Center Moriches and Melville) on a trade-only basis. A consumer-channel layer is executed via retail partnerships, most notably Home Depot carrying the Ace of Hearts Anthurium and other branded lines. At peak holiday periods the company packages and ships in excess of 1 million plants per week while maintaining quality controls; pricing is not publicly disclosed, with wholesale customers quoted directly and retail pricing determined by channel partners. No external equity, debt, or venture funding has been disclosed; ownership and control remain entirely within the Weiss family.
