Geum quellyon, commonly called scarlet avens, Chilean avens or Grecian rose, is a perennial herb in the family Rosaceae. It is native to the central and southern regions of Chile. G. quellyon has been introduced to other countries including Belgium, Bolivia, and the United Kingdom, where it was first planted in 1826.
Description
Macroscale
Plants reach a height of between 6 and 100 centimeters (2.4 and 39.4 inches). Leaves are compound, with between 3 and 10 pairs of leaflets. G. quellyon grows a thick taproot which smells of cloves when broken due to the presence of aromatic compounds. Flowers vary in colour from yellow-orange to pink-red.
Microscale
When in metaphase, somatic chromosomes of G. quellyon (and of G. magellanicum, another species of Geum native to Chile) are shorter and fatter than those in other Geum species.
Geum quellyon is commonly cultivated as a garden ornamental, and in that context is sometimes called Geum chiloense. G. quellyon grows best in full sun to part shade, in moist but well-drained soil. Plants become damaged and do not recover well if exposed to temperatures of −4.4°C (24.1°F) or below.
Geum 'Blazing Sunset', which produces brick-red double flowers on tall stems from June to September. It grows to a height and spread of approximately 60 centimeters (24 inches).
Geum 'Lady Stratheden', also known as Geum 'Gold Ball', which produces yellow semi-double flowers. The Royal Horticultural Society has awarded Geum 'Lady Stratheden' the Award of Garden Merit.
Geum 'Mrs J Bradshaw', which produces large semi-double flowers from June to September. It grows to a height and spread of approximately 60 cm. It is often planted in cottage gardens. The Royal Horticultural Society has awarded Geum 'Mrs J Bradshaw' the Award of Garden Merit.
Geum 'Totally Tangerine', which is a hybrid of G. quellyon 'Mrs J Bradshaw' and G. rivale. It grows to a height of 90 centimeters (35 inches), and produces sterile, peach-orange flowers. It is subject to plant breeders' rights in the European Union and the United Kingdom until 31 December 2036.
