What Trillium Landscape Design, Llc does

Trillium Landscape Design, LLC is a New York City-based landscape design firm founded in 2016 that provides end-to-end residential landscape services across three integrated service lines: custom Landscape Design (conceptual plans and planting designs for terraces, rooftops, and backyards), Garden Installation (full implementation including outdoor kitchens, arbors, herb gardens, and perennial plantings), and Garden Maintenance (ongoing multi-day-per-week care including pruning, weeding, watering, and seasonal plant rotation). The firm specializes in challenging urban microclimates — shaded brownstone backyards, elevated terraces with limited soil depth — and serves primarily high-net-worth residential property owners in the NYC metropolitan area, with select institutional work including landscape management for the United Nations Secretary General's residence.

The company's business model combines one-time project-based fees for design and installation engagements with a smaller but stickier recurring revenue layer from multi-year maintenance contracts, several of which have been in place for five or more years. Pricing is quote-based and not publicly disclosed; project economics vary by scope and complexity. Go-to-market is primarily direct client engagement supported by a curated portfolio website, earned media coverage in luxury design publications (Luxe Interiors + Design, December 2023), and professional credentialing through the Association of Professional Landscape Designers (APLD), which awarded the firm the 2024 Small Gardens recognition.

Operationally, Trillium is a boutique micro-business of 1–10 employees operating on a founder-led delivery model, as evidenced by client testimonials referencing a singular lead designer ("he"). The firm holds no disclosed technology platform, patents, or institutional investment, and has no disclosed funding history. Its competitive positioning rests on proprietary horticultural knowledge suited to NYC urban conditions, long-tenure maintenance relationships that create switching friction, and earned brand credibility through industry awards and luxury press features.
