So far this corn is doing very well.

This monsoon has been one of the best I've ever experienced in many years and I've lived in AZ for 43 years. Glass Gem does extremely well in this type of climate I planted 4 rows with approx 25 in each row (1 ft apart). They are 7 ft tall, tasseled, and ears are forming. I won't know the full picture until I harvest.

1st Time planting corn

Hello from Upstate NY! I wasnt sure how these would do up here. I bought my seeds in fall of 2020 and planted them spring of 2021. I actually planted them in late spring, and they have been doing really well especially considering we do have a short growing season. I planted a small patch in my yard and most of the stalks survived. Majority of the stalks are well over 6 feet tall and have begun to produce cobs. We havent tried them yet, but planting these was more as a remembrance for someone, then the corn itself, so Im extremely pleased with how the corn is growing. As my other garden seeds have flopped this year, I am eager to try some of the other seeds offered here!

First time at native seed search

I didn't have much luck growing corn last year. This year I'm trying heirloom seeds here in Tucson and should have success with native seed search on my side!
