Geums: Light, Water, and Soil Conditions for Growing Avens

Geum (aka Avens), Geum spp.

Once gardeners get to know geums (also known as avens), a relatively uncommon perennial, they often seek out others. Kirsty Wilson, the author of Planting With Nature and the herbaceous supervisor at The Royal Botanic Garden Edinburgh, first planted Geum ‘Totally Tangerine’ in her award-winning show garden, The Coffee Garden back in 2019. The garden’s palette of lime, orange (including ‘Totally Tangerine’), and brown was inspired by the colors of coffee bean fruits. Today, Wilson has a list of geums she likes to use in her designs.

It’s not just professional plantswomen like Wilson who have discovered the joys of geums. Ohio gardener Brad Johnson, the content creator behind @garden.evolution, says he fell in love with geums accidentally. “I stumbled across the cultivar ‘Mai Tai’ at a local garden center and gathered a couple up just to try them out,” he says. Johnson quickly found himself seeking out more—and with good reason: Geums are easy to grow, loved by pollinators, and long blooming; they even have lovely foliage.

Here’s everything you need to know about growing geums.

Members of the rose family, the rhizomatous perennials’ blooms resemble tiny roses, which look great in the garden and in cut bouquets. “I love the repeat flowering, and the flowers last a long time—geums really do perform,” says Wilson. Kate Gould, a garden designer and founder of Kate Gould Gardens in London, likes geums because she says, “they add punch, depth and impact.” More widespread in the United Kingdom than the U.S., geums are well worth seeking out.

Suitable for zones 3-9, geums are relatively tough plants, according to the experts we spoke with. Gould says, “Give them some sun or light shade and a soil that is well worked, and they will easily reward you.” Johnson finds the flowers last longer with some afternoon shade but they can handle full sun with extra moisture (though they may not be so happy in full sun if you live further south). Johnson also notes that clay soil doesn’t seem to bother them.
