Not a spiraea :-) Kolkwitzia amabilis, aka beauty bush.

Aka Linnaea amabilis.

Did I miss yet another name change?? Sigh.....I just can't keep up!

Spireas never produce trumpet shaped flowers. Regarding the expanding of Linnaea

Most botanists resisted placing other species in the genus, treating Linnaea as a monotypic genus. However, molecular phylogenetic studies from 2001 onwards showed that a number of genera were related to Linnaea (the "Linnaea clade"), although one of them, Abelia, was not monophyletic. In 2013, to maintain monophyletic genera, Maarten Christenhusz proposed merging Abelia (excluding section Zabelia), Diabelia, Dipelta, Kolkwitzia and Vesalea into Linnaea.[1] This proposal has been adopted by some secondary sources, including Plants of the World Online.[2][3] However, other sources prefer to maintain the segregation of Linnaeoideae into the traditional genera on grounds of morphology, biogeography and nomenclatural simplicity.[4][5][6]

Thank you very much.
