Could the mildew be due to water stress? I have been amazed how easily I can force roses to mildew and rust here by keeping them too thirsty. Much of both have cleared up simply by increasing the water.
Mildew seems rather common in Iceberg descendants, with some exceptions.
High Voltage seems to display even coloration, which i think is uncommon in yellows. It definitely has a slight buttery apricot undertone that is barely visible. I am curious if this rose is the result of a Buck/Austin crossing. It seems to lack some of the key elements of other yellow lines that are well-known.
I am still confused as to what to cross it with. I am heading towards the idea of High Voltage x Whimsy, instead of High Voltage x Toprose.
I’d go for both those Michael. High Voltage sounds healthy enough to be mixing it round a lot, even if it does mildew some.
I wonder if High Voltage is in Oz?
Probably not now, but maybe in the future. I spoke with Ping Lim last year just before his trip to Australia where he was having a meeting with Treloar Roses to possibly import some of his roses. I didn’t hear how the meeting went.
I,too, have seen HV and it’s descendants mildew here and in Bill Radlers garden. Luckily that doesn’t affect it’s usefulness as a landscape rose around here.
I’ve been trimming most of the first buds off of my OP seedlings, but haven’t seen many if any that are any darker than Mom. An occasional light pink, but mostly light yellow to cream. Crosses with Carefree Sunshine have resulted in darker yellows.
The above average hardiness of HV might make it worthwhile to cross with Toprose. I would love to be able to make that cross. If I can get a little more First Impression pollen off of my young plant I think I’ll use that. HV is fun because it sets fat hips.
It would be great to have some of Ping’s material to play with, downunder.
George, on another forum in Oz, one of the Teloar family is a member, when he returns from holidays I will email him and ask.
ok David M
I really like High Voltage. It is more crown hardy here in MN than the other Bailey yellow roses- Yellow Submarine, Centennial, and Yellow Brick Road. It is tall and upright in habit compared to the others too. That’s interesting someone mentioned a similarity to ‘Singin’ in the Rain’. That is in the background of ‘Yellow Submarine’. From the known pedigrees of those that are reported, it seems like there are likely some common parents in their backgrounds.
