Garden phlox is a standby in late-summer gardens - even though it starts blooming in June, it's in late July and August, when it is still in bloom while the early bloomers have given up and the fall bloomers have yet to start, that it is at its most valuable. We've had a white Mt Fuji phlox in our garden for many years; it's not in the most hospitable place, and usually doesn't do very well, with powdery mildew attacking every year. So recently we decided to try a few new varieties: 'Laura' and 'Eva Cullum'. Although the latter is supposed to have excellent powdery mildew resistance, we found it was attacked severely, while 'Laura' held up nicely. It may be the different positions in our gardens, but I'm not convinced about the claims of resistance...
In recent years, we also have plain deep pink phlox reseeding in our side garden, popping up in various places and contributing nicely to the border in its messy late-July state, as seen in the photo above right.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston. About my plant portraits

Your site was found through a complex search for Eustoma, a plant my daughter found in a nursery and one I was not familiar with. Keep up the great work. |
Irena Montuori, Guelph, Ontario | Oct 30, 2009 | There is a very lovely Phlox - Phlox paniculata "David" - it is a pure white variety, very fragrant and I have not seen any mildew on it for the last 20 years. It is a performer! After it flowers, cut off the blooms and it will rebloom later in the season. ... and best to avoid mildew is to give the plant plenty of air circulation. Love your site Rob. |
veronica utter | Apr 23, 2010 | I am with you concerning the claims of resistance to mildew. I was surprised to see Irena's entry on David. I got David which was supposed to be mildew resistant as well as Jacob and they both got mildew. Red Riding Hood and another pink one was fine and they were not considered highly mildew resistant. Just can't figure that one out. They were all in a line. I would have expected them all to have mildew. Go figure.
I am loving this site. Thanks. |
