Origin & Breeding History: 'Spring2' originated from an open pollinated cross conducted by the breeder, Gijsbertus Verhoef, in Hazerswoude, the Netherlands in late spring 2005. The cross was made between the female parent Weigela florida variety 'Tango', and an unknown male parent. From the resulting progeny, 'Spring2' was selected as a single plant in July 2007 based on its compact plant growth habit, a dark purple-black summer foliage and the number of flowers. 'Spring2' was first asexually propagated by softwood cuttings in June of 2008 in Hazerswoude, the Netherlands.

Tests & Trials: The comparative trial for 'Spring2' was conducted outdoors during the spring and summer of 2020 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 12 plants of the candidate variety and reference varieties. All plants were grown from 6 cm rooted liners that were each planted into a 7.5 litre container on June 28, 2019. The plants were overwintered in a polyhouse and moved outdoors in late May of 2020 to a drip irrigated field where they were arranged in rows with approximately 1 metre spacing between plants. Observations and measurements were taken from 10 plants or parts of plants of each variety on April 15, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
