Lost Horizons is for sale


Lost Horizons is an independent specialty nursery and one of Canada’s leading sources for hard-to-find perennials, ferns, ornamental grasses, and woody plants. Operated by expert plantsman and garden designer Larry Davidson, Lost Horizons has proudly served plant collectors and knowledgeable gardeners in the Greater Toronto Area and Southern Ontario area for over two decades.

We’re passionate about plants

We offer a huge variety of plants that are not available at other nurseries. These range from native plants to sought-after hybrids; from sun-loving alpines and prairie plants to shade-growing woodland plants; and from old cottage garden favourites to unusual species and cultivars that have been sourced and collected from all over the world.

Locally-grown & pesticide-free

Our plants are pesticide-free and screened for invasiveness. New varieties of plants are trialled on-site for vigour, hardiness, architectural value, and floral quality. Many of our plants are propagated and grown on site and are well adapted to local conditions.

Extend seasonal interest

One of our goals is to extend the garden’s seasonal interest by offering plants that have structural appeal or bloom not just in the summer, but well into the fall as well.

Our specialties include:

Hellebores Epimediums Magnolias
Japanese Maples Cypripediums Arisaema
Roscoea Salvia Aconitum
Campanula Coreopsis Heuchera
Hosta Japanese Peonies Phlox
Polygonatum Hardy cyclamen And more…
