OK this is not Forsythia, although it is in the olive family (Forsythia, Fraxinus, Syringa, etc.). This is Abeliophyllum distichum var. roseum (pink flowers). It is often called dwarf forsythia and it flowers just a bit earlier than Forsythia adding a bit to the confusion. The plant is a rounded 4-6 foot shrub and in full flower it has quite a lacy appearance. The flowers are quite fragrant, sort of honey scented. U. of Minnesota says it will grow well enough in zone 4. No cold damage over the winter of 2021, and it handles shade fairly well too. TPP tries these plants so that you don't have to.
