Located in Saint-Eustache, Quebec, La Maison des Fleurs Vivaces – Sème-Saveurs is a diversified agricultural business specializing in the production of herbs, vegetables, and perennial plants.
Driven by values of sustainability, biodiversity, and community-focused agriculture, the company partnered with Harnois to install a greenhouse system adapted to their multi-crop needs.
Harnois Greenhouse supports diversified production
To meet the varied needs of their herb, vegetable, and perennial production, La Maison des Fleurs Vivaces implemented a hybrid greenhouse system composed of both freestanding and gutter-connected Harnois greenhouses.
This combination enables flexible zoning, shared space management, and optimal growing conditions for multiple crop types. The entire project starts early in February to be the first on the market, even before the garden centers are ready to open for the public.
Key features include:
- A galvanized steel frame built to withstand high snow and wind loads
- Natural light optimization supporting strong and healthy plant growth
- Integrated weather station, ventilation and heating system for precise climate control
- Modular interior layout suited for trays, rows, or vertical growing systems
- Anchoring and drainage systems adapted to seasonal soil conditions
This hybrid design enables the farm to scale, segment production areas, and maintain ideal growing environments for a diverse range of crops.
Why La Maison des fleurs vivaces chose Harnois Greenhouses
When planning to scale up their production of herbs, vegetables, and perennials, La Maison des Fleurs Vivaces needed more than just a structure; they needed a solution tailored to the realities of diversified small-scale farming.
They chose Harnois Greenhouses for several key reasons:
- Proven expertise in structures adapted to Quebec’s agricultural climate
- The flexibility of freestanding and gutter-connected models for mixed and seasonal production
- A modular design suited for collaborative projects and evolving space needs
- A reputation for responsiveness and local support at every stage
By working with Harnois, the team gained a high-performance greenhouse that supports both productivity and shared values such as resilience, sustainability, and innovation.
Benefits for horticulture operations
La Maison des Fleurs Vivace now operates a 400,000 sq. ft. cultivation complex, allowing them to produce 850 varieties of plants (perennials, herbs, and vegetable seedlings) all year long.
Since the installation, the greenhouse has brought several benefits to the team:
- Extended growing season: early starts in spring and continued harvests into late fall
- Consistent quality: better control of temperature and humidity for sensitive crops
- Space optimization: shared layout adapted for trays, hanging baskets, and row planting
- Reduced pest pressure: better crop protection through barrier controls
