'Astoria' has a shorter plant height than the reference varieties. 'Astoria' has no anthocyanin colouration in the stem while the reference varieties have weak to medium anthocyanin. 'Astoria' has white corolla colour while the reference varieties have red-violet corolla colour. The tubers of 'Astoria' have yellow skin while the tubers of 'Rosara' have red skin. 'Astoria' has a smaller light sprout with weaker anthocyanin colouration at the base than the reference varieties.

Origin & Breeding History: 'Astoria' originated from a cross between 'Gesa' and 'Cilena', made in Windeby, Schleswig-Holstein, Germany in 1988. 'Gesa' originated from the cross 'Steffi' x 'Taiga' and 'Cilena' originated from the cross 'Gelda' x 'Hirta'.
Tests & Trials: Trials for 'Astoria' were conducted in Drummond, New Brunswick in 2006. All entries were planted in single-row plots. Plots consisted of rows 22 metres long with 30 cm in row spacing and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
