Phlox paniculata ’Alma Jansson’

A garden phlox with dark green foliage and light purple flowers with a white eye. The variety has small flowers, only about 2.5 cm in diameter. The flowers have a subtle, pleasant fragrance. During trial cultivation, the variety has proved healthy. It spreads with runners without having an aggressive growth habit.

Height: 110 cm

Bloom time: At the trial cultivation at the Swedish University of Agricultural Sciences in Alnarp in the south of Sweden, this cultivar has started to bloom in early July and bloomed for about one month.

Bloom colour: Light purple flowers with a white eye in the centre.

History: Garden phlox 'Alma Jansson' comes from a smallholding in Roslagen in Uppland. Two of the people who made inventories for the call for perennials noted this phlox when they visited the home of the nearly 90-yearold Stina Jansson. In the summer of 2005, they visited her in Edsbro and in a border on the farm this tall, light purple phlox grew. It has been on the farm at least since 1939 when Stina Jansson moved in. She got married that year and she and her husband moved in on her parents-in-law’s farm. It was her mother-in-law, Alma Jansson, who took care of the plants in the garden. "Everything comes from Grandma. She had such beautiful flowers", said Stina Jansson. Alma Jansson was interested in gardening and planted many of the perennials on the farm. We do not know where she received or bought this variety, but it was noy newly planted in 1939.

In the summer of 2007, the Swedish radio show ‘Odla med P1’ made a feature about the inventories of old garden perennials. The show, named "In Search of Grandma plants" visited, among others, Stina Jansson and she told the story behind her plants.

Collected in: Edsbro in Uppland in Eastern Sweden.

How to grow garden phlox: The garden phlox prefers a nutritious and moist, but well drained soil. It thrives in full sun or light shade. The bloom time is extended if the plants are deadheaded.

Sales: The variety can be purchased at nurseries and garden centers from spring 2013.
