Hi Joy. I had one some years ago. I never had any issues with mildew on it. I just recall, that it really had stunning blooms, that appeared to change colors between blue, to nearly violet. Then, it seemed to have suddenly mysteriously disappeared entirely ! Maybe, somebody saw it, & liked it also.
I've ordered another, & hope it is true to name cultivar. Last time, I got gypped !
I tried 'Blue Boy', a couple of times, & that one would seem to just die completely, & had no idea why.
There is a taller one named 'Dusterlhoe' (sp.?) which goes by another name here, in English. It was (more purple,)
yet quite a good grower, & flowered well, down this way.
Nowadays, there are quite a number of varieties. So many, I can't keep track of them all ! Including shorter kinds, & in various color Series.
While I have difficulty locating a white with slightly yellow centers, that had quite huge panicles. I think it was named 'Fuji', or 'Fujiyama', & ever since that white 'David' came along, haven't noticed it offered, since then.
There is a "reverted" form of 'David', though that color may not be quite to your liking. Although it is supposed to grow well, & be somewhat more resistant to that powdery mildew, also. Haven't tried that one yet.
I hope you find one to your liking. They do tend to take awhile to really begin to get started growing in Spring.
