Re: HYB: evaluating seedlings - frost/freeze damage

Various things - freeze damaged foliage turns brown or breaks out in massive leaf spot or rots. Compared to other cultivars that don't.
Buds may be burnt on the outside, like you describe, or if it's bad enough, stop growing and shrivel up (blasted) or rot.
If the buds aren't killed, they may go on to various degrees of deformity, from missing parts to the edges of petals missing or shriveled. Slight damage after bloomstalks are well along, will often result in somewhat normal flower development, but with varying amount of puckering of petals.
Up to my eyeballs in tons of bloom, toughest ones are now showing no damage. But still seeing damage on some that are opening. TB bloom is close to peak. 

<Linda, Betty... anybody frosty...

I'm feeling a little... dare I say, left out...y'all keep talking
about "obvious" frost damage and I just have no I-dee what you are
seeing. This seedling looks to me like a lot of fun for one thing...

Is there some tell tale sign that lets you know that a bud got zapped?
For example, I've noticed on some of my irises that the [outside
green part] of the buds is white and papery on the top half. Could
that be what you are talking about?
