Overview
We’ve combed through a fair bit of info on Trader Mulberry by Dr. Jim Walla, who released this variety in 2015. Trader is perhaps the most cold-hardy named variety (some debate with Northrop), as the original tree survived -44°F near Oriska, North Dakota.
A Hardy History
The history of Trader is quite fascinating. It was brought over from Germany by the Trader family when they immigrated to the U.S. in 1882. The original tree is still in North Dakota, having borne fruit for over 140 years. According to Walla, he believes this to be either pure Morus alba, or largely alba with a small amount of M. rubra, as its cold hardiness supports this—considering rubra is much less cold-hardy.
Fruit Production & Flavor
It will produce an abundance of large, sweet, glossy black fruits throughout the entire summer. The berries are very small the first year and don’t set very heavy fruit in the first few years. The fruit size should increase every year after it first bears, going from 1/2” to 1 1/2” several years later. The fruit is excellent for fresh eating, preserves, and juice/wine. Poultry and livestock love both the fruit and the leaves.
Growth Habit & Hardiness
Can be grown as a multi-stemmed shrub, as a single-trunk 35' tall tree, or much shorter if summer pruned. Will begin fruiting at only 3 years, and will produce for a century or more! Walla observes that this tree could potentially be grown in zone 3a, but he does not know of any currently growing that cold. Safe to say this is hardy to Zone 3b, or -35°F.

Shipping restrictions: state invasive plant law
White mulberry (Morus alba) is a listed invasive plant whose sale, distribution, and import are prohibited in Ohio (OAC 901:5-30-01) and Indiana (312 IAC 18-3-25). As noted above, ‘Trader’ is understood to be pure or predominantly Morus alba, so we cannot ship this tree to Ohio or Indiana.
Also restricted in: Wisconsin, where Morus alba is a Restricted species under NR 40 with an exemption only for male (non-fruiting) cultivars, which does not cover a fruiting selection like Trader. We do not ship this tree to Wisconsin.
Orders placed to a prohibited state will be cancelled and refunded.
