Phlox
paniculata "Prospero" (False)
Early flowering and
mid-tall Flowers look "bluer" in the evening. Flowers for
a long time and very healthy. One of our favourites. Very fragrant.
This is almost certainly not the true
and original "Prospero" as bred by Karl Foerster. I've got the
same plant under the name from two different sources so its is being
commonly sold as Prospero in the UK. I'd be interested to hear
opinions on what the true name is.
