Kevin,
It seems we are at a loss for pure grandiflorums and wulfeniis here in the pacific northwest. I've tried to purchase both before and think in both cases I wound up with hybrids not pure species.
The differing genetic combination leading to a completely different phenotype makes sense. I had noticed some pictures of the white flowering 'Baby Boo' show red leaf backings, so perhaps that one isn't an albino but has a different gene that turns flowers white. So many of the arachnoideums look similar that I imagine it'd be tough to select for distinction. Pure arachnoideums have been a very small segment of my program, I do have some self crosses from 'Spumoni' and an arach cross or two, but I'm mostly interested in crossing them to other species. Yes the biggest issue with breeding for blooms is that to make optimal selections you'd have to wait till each plant has finished it's lifecycle completely, that's a lot of time. The ones I've bread for flower color this year will likely be selected on the basis of the rosette, and I'll just cross my fingers that the blooms look as I'd imagined on whichever ones I select. One thing I've considered to solve the issue of space when selecting for blooms is to only keep the first rosette and an offset or two for each seedling, discarding all other offsets to minimize the volume of potentially unwanted plants until you've seen all of them bloom and a selection can be made on the basis of the flowers. Just a thought at this point, I don't know how it'll work out in the end, but I have crossed for blooms and will do whatever I can within reason to see that the proper selections are made, be the blooms a second or first priority over the rosettes.

nice day today, I'm considering moving some 1 year old seedlings from a shady bed to a sunnier one so I can see what they look like with good light next year, it's a lot of work just to adjust light exposure, and it's getting late in the year for transplanting, don't know if it's worth it to carry them over, and I only have a few hours of daylight left. What do you think Kevin? ever try selecting from a shadier area?
