Geum

There are over 50 species of plants in the Geum genus, commonly called Avens. They are rhizomatous perennial herbaceous plants in the rose family and are native to Asia, Africa, Europe, and North and South America. The genus name is from Latin and means scarlet. They generally grow 9-18 inches tall in a mounding habit. There are Geum species that are native to NC, especially in the mountains and Piedmont.

They all have attractive, divided dark green leaves and small, bright flowers with 5 or more petals. Avens grow best in cool climates, and while they tolerate dry soil, they prefer moist but well-drained soils.   They can die if exposed to wet winter soils.  They grow in full sun to partial shade but can struggle with the heat and humidity of southern summers.  Yearly division is necessary to keep plantings vigorous.  Deadhead flowers encourage more bloom but leave some spent blooms on as seed heads are attractive fluffy plumes. 

Does well planted in mass, in borders, English gardens, cottage gardens or rock gardens, and the leafy green foliage makes a nice ground cover after bloom.

Insect, Diseases, and Other Problems: No serious insect or disease problems. Root rot can be a problem in poorly drained soils, particularly in winter.  May be short-lived in heavy clay soil or hot summer climates.
