Gamm Vert has not changed hands in the classical sense. The brand remains anchored within the scope of InVivo Retail, a subsidiary of TERACT, which is itself controlled by the agricultural cooperative InVivo. What has changed is the doctrine: a refocusing on gardening, a massive return to franchising, and the structuring of a portfolio of brands (Gamm Vert, Jardiland, Delbard, Jardineries du Terroir) managed as an integrated group.
TERACT and InVivo Retail: the capital structure behind Gamm Vert
The control scheme is cooperative, not shareholder-based in the stock market sense. InVivo, a union of French agricultural cooperatives, holds TERACT. TERACT operates InVivo Retail, which directly manages Gamm Vert and the other gardening brands of the group. No investment funds or sector competitors have entered the capital.

This architecture explains why talking about a “buyout” can be confusing. We are rather observing an internal reorganization of the brand portfolio: loss-making sites have been divested, peripheral activities (bakery under the Louise brand, specialized food) have been integrated or repositioned under the group banner. The logic is one of industrial refocusing, not a sale.
To understand in detail who bought the Gamm Vert franchise, it is necessary to read “buyout” as a strategic takeover by the parent cooperative, and not as a transfer of ownership to a third party.

Return to the Gamm Vert franchise: what the model changes for operators
TERACT is considering the return to franchising for all of its Gamm Vert stores operated in-house. This is a structural shift. The sites held as branches represented a heavy fixed cost burden, particularly regarding leases and payroll.
The transition to franchising transfers the operational risk to the franchisee while maintaining the network fee and access to the group’s private labels. For current operators, this means an initial investment, increased management autonomy, but also a heightened dependence on supply conditions dictated by InVivo Retail.
In practice, operations like that of Cavac Distribution, which has taken over several Gamm Vert stores, illustrate this movement. Local cooperatives or independent entrepreneurs become the operational contacts, while TERACT retains control over the brand, commercial policy, and purchasing center.
Implications for current employees
The transition of a site from a branch to a franchise potentially jeopardizes existing employment contracts. The conventional transfer of employees depends on the effective takeover of the business by the new franchisee. Positions are affected at each conversion, depending on the size of the store.
Private labels and food diversification at TERACT
The product strategy constitutes the most tangible differentiation lever for the group. TERACT claims over 10,000 private label references intended for its entire network of garden centers. This volume gives Gamm Vert stores a direct margin advantage over multi-brand independents.
Food diversification (grocery, local products, short supply chains) is now consolidated at the group level. Gamm Vert and Jardiland share ranges, allowing for economies of scale in sourcing. Gamm Vert’s positioning as a “rural garden center with local offerings” thus distinguishes itself from Jardiland’s urban positioning, but both brands draw from the same supplier catalog.
- Private labels covering plants, tools, amendments, and grocery, negotiated centrally by InVivo Retail
- Local food ranges adapted store by store, with a group framework for traceability and merchandising
- Logistical pooling between Gamm Vert and Jardiland on high-turnover references

CRM and digital ambitions of the Gamm Vert network
TERACT is structuring a unified customer database for all its gardening brands. The goal: to manage targeted CRM campaigns, cross-reference purchase histories between Gamm Vert and Jardiland, and personalize promotional offers by catchment area.
We observe that the group is actively recruiting for these profiles (CRM campaigns, data, digital marketing), a sign that the project is in the industrialization phase. For a network of franchisees, this is a concrete argument: the brand not only provides a name and a catalog, but also a customer loyalty and knowledge tool that few independent garden centers can develop on their own.
What this changes in-store
The Gamm Vert franchisee will benefit from a centralized dashboard to track foot traffic, average basket size, and campaign conversion. The trade-off: a systematic reporting of cash register data to the central office, which reduces the commercial opacity that some independent operators enjoyed.
Store concept and territorial network: development priorities
The new Gamm Vert points of sale feature revised surfaces, rethought merchandising, and a clearer separation between plant offerings, tools and machinery, and food space. Field feedback on recently renovated stores mentions “larger and clearer spaces.”
The territorial network remains dense in rural and peri-urban areas, where Gamm Vert has historically had its customer base. The development strategy prioritizes:
- The conversion of the last branches into franchises to lighten TERACT’s balance sheet
- Targeted openings in white areas where neither Jardiland nor Gamm Vert are present
- The renovation of existing stores according to the new concept, largely financed by the franchisees
- The maintenance of geographical complementarity with Jardiland to avoid intra-group cannibalization
The TERACT group is thus orchestrating a transformation that simultaneously affects the legal model, product offering, digital aspects, and physical format of Gamm Vert. The brand has not been sold; it has been repositioned within a cooperative ecosystem that relies on franchising to accelerate without burdening its cost structure. The coming months will reveal whether potential franchisees respond positively to the conditions proposed by InVivo Retail.
