Re: iris DIGEST V1 #185

It indeed it is the seeds that were kept over winter, but didn't germinate.  

No seeds by June as peak TB bloom here is about June 15th.

There are usually a number of seeds that don't germinate, usuaually the ones that got planted the latest (about Feb)

They  don't dry out. 

Fridge does get opened often in the summer as all the cold drinks are also stored there. As the trays are stacked up, 

there does not seem to be much temperature fluctuation. I had a min/max thermometer in ther and it was about 40 at bottom of  

fridge and about 45 at top. Only a few degrees of variation each day.

The pots go under the grow lights inside. I have  a three layer light table with each layer 4 X 8 ft. Right now I'm transplanting 

 the seedlings so each plant has its own pot. Just over  half done.

One year  I forgot about them and found them germinated and frozen near end of December.

?No losses from the freezing, it didn't seem to faze them.

Chuck, when you say 'ungerminated', I'm assuming you mean seeds that did 

not germinate earlier that year, rather than fresh seed from that summer?

Interesting - the only time any TB seeds have germinated in the fridge 

here was after 5 months.  I wonder if it takes longer without 

temperature cycling up and down.

Have the pot contents dried or have they been kept moist until put into 

the fridge?  What are the usual temperatures they have experienced 

between spring and the time they go into the fridge?
