Mark Akimoff is the owner and head grower at Illahe Rare Plants

From Habitat to the Home Garden: Cultivating Alpine Plants from Mountains Around the WorldJoin Mark as he shares stories of his adventures to far-flung landscapes, from the Southern Alps of New Zealand and the Andes of Chile to the flower filled tundra of Alaska's White Mountains. This talk explores closer-to-home regions, including the Cascades, Siskiyous, and Wallowas as well. This talk highlights many remarkable rock garden plants observed in their native habitats and the challenges and triumphs of cultivating these unique alpine species in his Willamette Valley Illahe nursery. 

Mountain passes provide a unique opportunity to visit alpine areas to botanize. In 2020, Bella and Barbara travelled to Argentina to travel with Marcela Ferreyra into the Andes. Together they drove up and into the eastern Andes in Argentina, then crossed over into Chile to explore the western Andean slopes. This presentation will focus on their experience of four very different mountain passes and what they learned about the flora they found there.​

How do we build beautiful rock gardens when climate, rather than horticultural tradition, becomes the primary design challenge?

Drawing on more than twenty years of gardening in British Columbia's interior—from the subalpine landscapes of Sun Peaks to the arid valley floor of Kamloops—Jay Akerley explores an evolving approach he describes as climate-adapted ecological rock gardening. Rather than beginning with plants alone, the garden is shaped by climate, hydrology, mineral soils, and ecological processes.
