Hi, everyone,
Ed, thanks, I had read that Victorian Lace in some gardens is rust susceptible. Years ago when I asked about it on the old Dave’s Garden forum, I heard back from someone who lives in a rust zone in Georgia that it’s rust resistant in her garden, too. But I’ve gone back and edited my previous post to reflect the ambiguity. I actually assumed that people reading these posts would use them only as a starting point of research. For all I know, any number of cultivars in my garden that are stellar and rust resistant will turn out to be disfigured by rust in other locations. I’m still rather amazed that Wild About Sherry – a great grandchild of the notoriously rusty Admiral’s Braid – was surrounded by rusty daylilies, but completely rust resistant. Were its rust susceptibility/resistant genes inherited from other great grandparents rather than Admiral’s Braid?
There are only a few cultivars that I grow that are rust-rated in ATP’s database (or Sue Board’s Rust Survey). But, it’s worth noting that rust scores for Ming Porcelain and Tuscawilla Tranquillity, which you also grow, are included in ATP’s database. Both of them have 1.3 scores, which indicates that there are reports indicating some degree of rust susceptibility; a ‘perfect’ rust resistance score is 1.0, and a 5.0 score indicates extreme susceptibility. It’s a shame that neither the sources nor the calc used to come up with the scores is provided. But, I have to assume that the scores have some degree of validity. In any case, I’ve edited my previous post to show this, too. Also, per the ATP database, the following don’t have perfect 1.0 rust resistant scores: Joan Senior (2.5), Emerald Splendor (1.7), Woodside Ruby (1.7), and Bela Lugosi (1.5).
Mark, a sincere welcome from me, too! I instantly realized who you were when reading your first post, but since you didn’t provide your name in your profile, I didn’t want to ‘out’ you. So, I left that for Ed to do. : )
All the best – Elizabete
PS Maryl, I just saw your post and thanks for the additional lists of cultivars! As for Victorian Lace as a parent - at least in my garden Fred's Lillian's Fringe Benefits (whose pollen parent is Victorian Lace) had the foliage of extremely rusty cultivars draped all over it when some workmen moved potted daylilies around on my patio. Yet, Lillian's Fringe Benefits never developed a single spot of rust. Don't get me wrong, I'm not suggesting it as a potential parent! (At least 30% of VL's blooms had a decidedly rectangular form in my cool summer temps that wasn't particularly appealing, in any case.) But, anomalies do occur.
