So late last fall I had three pots of Division 6 crosses that had 7-10 hairpins germinate late in the season. I pulled them from the pots and potted them in new pots to be put under lights in the winter. All three crosses were pretty vigorous and did well. They were transitioned outside where they sustained some lily beetle damage but have still remained very vigorous. Particularly, one cross (Rosthornii X Henryi) X Freda Willis. One of the seedlings is even throwing up a stem now!

Those look quite robust, Joe. Are you planting them in the ground now?

Can't wait until i get to that point

Nice work joe

The late ones are those particular seeds that required a cooler temperature to germinate (as compared to the rest of the lot). They were just laying there, waiting for cooler media temperature. I've had it happen when seed was started normally at the typical 65'F to 70''F, where only about half came up as usual and the remainder didn't come up until late Oct./early Nov. By then the nighttime lows were often below freezing but I think that's what it took. I did the same as you, I separated the two groups, etc. But one thing I didn't do and I should have, was follow up and compare the differences of the two groups as mature plants. Maybe that's something you might want to do since you have the opportunity.

Well Lorn, I can't really compare because I lost the other groups over the winter. I have a hard time with division 6 seedlings getting too wet in the fall and rotting. So my plan is to get them in the ground before the later fall rains, which shouldn't be a problem for them to handle in my sandy soil. I've had two years of very vigorous seedlings, Lorn's Lime and Regale Album all get too wet and rot before getting transplanted so now I know that I have to get division six stuff in ground before late fall.
