I got out a few walnuts and cracked them today.
Cranz is a small nut on a productive tree that matures relatively long season. I think it would be best adapted from Iowa south to the gulf coast. The kernels are rounded which lends to easy cracking. My only complaint is that I like slightly larger nuts. Cranz should fit in very well with Sparks 127, McGinnis, and Sparrow in Iowa and similar midwestern climates. The only disparity is that McGinnis matures 3 weeks before Cranz which means separate harvest would be required.
Farrington was as I remember it, a large nut that cracks fairly easy. Eating quality is very good. The trees are moderately productive and have made a crop every year for at least the last 6 years. I’m adding this one to my short list of varieties that are good enough to propagate commercially here in the deep South.
Thomas is a medium large nut with excellent quality from trees that are highly productive. I rank Thomas as an outstanding walnut. Hands down, it is the best of the old vairieties. Only Neel #1 IMO ranks as good as or slightly better than Thomas.
Neel #1 is a large nut with excellent quality from trees that are very productive. This is an outstandingly good nut. The only flaw I’ve found with Neel #1 is that it tends to darken if left in the husk too long. Maturity is about a week earlier than Thomas. I could easily harvest Farrington, Thomas, and Neel #1 at the same time.
