A combination of factors. But having said that, main factor is likely that pulling together of recessives involves inbreeding, building up of the already weak genes in southern plants.

Subject: [iris] HYB: recessive colors and plant health

It's rare to find introductions of recessive color patterns that will
survive in our climate.  Usually.  I think.

So is that just because most of the new recessive color breaks are
selected in climates so different from ours, or is there some additional 
inherent weakness in plants carrying recessive color genes, or (my
guess) the accumulation of recessives is so rare in any one seedling,
that the probability of it also hitting the lottery and having really
good strength/health in stressful climates is low.

Are seedlings that are fully recessive for some color pattern more
likely to have those 'weak' genes all in the same package?  Strong X
weak here (I always use strong for pod) seems to produce a lot of weak
seedlings, brings out the worst genes for pooe health in the strong parent. 

I'm just wondering how that skews ratios for recessive color patterns,
assuming the ones with a lot of recessives are among the weaker of the weak.
