Peony Registry

Received January 5, 2020. Tenuifolia species selection grown from seed purchased of Josef Halda. The seed origin was either from Bulgaria{JJH010768 VID [Bulgaria (Vidin)] …lowland open bushy slopes; vigorous clumps with very dissected leaflets and huge blood-red flowers}, or from the Caucasus region {JJH 0108850 KART [Caucasus (Kartli)]…Paeonia tenuifolia montane dry-rocky slopes; small clumps broader leaflets and smaller dark crimson flowers}. First year bloomed 2008, first year propagated 2011. Some prior distribution under the name being herewith registered. Flower form SINGLE. One flower per stem, size 2 inches (5 cm). Flower color light pink. Petals cupped, generally rounded, with edges fairly evenly, but shallowly crenulated. Carpels pale green, stigmatic surfaces creamy white. Pollen-bearing stamens. No fragrance. Very early bloom period. Very fine fern leaf foliage characteristic of the species. ‘Kinlen’ has larger flowers and better vigor than others of this type being grown at Solaris Farms, is not difficult to grow, and takes up very little space in the garden. Good fertility both ways. Good amounts of seed are obtained when using its pollen on tenuifolia ‘flora plena rubra’. Offspring are often red singles. Few red doubles and pink singles are produced from first generation crosses. When self-pollinated, approximately 95% of the offspring will bloom with single red flowers (typical P. tenuifolia) and the remaining will be pink (rosea form). This would indicate that this plant does not have simple recessive traits for the color pink, but rather a more multiple allele configuration or other genetic inheritance pattern. Named for Lois Kinlen. The seeds that gave rise to the seedlings from which ‘Kinlen’ was selected were obtained by sisters Lois Kinlen and Jean Halverson of Wisconsin, in 2001. Over the previous 10 years, Lois and Jean were generous in their donations to the Wisconsin Peony Society and the Minnesota Peony Society plant auctions, the avenue by which this peony arrived at Solaris Farms.
