A cannabis farm, care home and charity shop could be developed in Grouville, if plans are approved.
Permission is being sought for a new care home and Jersey Hospice Care fundraising shop on the site of Holme Grown.
Separate plans will also be lodged, by GroVida Jersey, to produce cannabis-based medicinal products.
Holme Grown wants to replace the unused garden centre and glasshouse block with a 50-bed nursing care home, operated by the LV Care Group.
The new fundraising shop would be built in the existing car park.
The medicinal cannabis plans will be run opposite and separately to Holme Grown by GroVida Jersey, who have applied for a licence to cultivate the drug.
The existing glasshouses at Fauvic Nurseries would be refurbished.
The company says discreet security fencing will be set up away from the road and fall between the existing treeline and glasshouses, so won't be visible from the roadside.
Bird and bat boxes would be installed there along with a wildlife pond, hedgehog houses and toad shelters.
GroVida Jersey Limited is a joint venture between UK renewable energy and agri-development company Oasthouse Ventures, and GroVida LDA Portugal,an established European cannabis cultivation and manufacture organisation.
The Holme Grown farm shop will continue to trade throughout.
