Description

The tree is distinguished by Fu (2002) as having "Leaf blade adaxially with densely curved pubescence. Flowers and fruits February - April".

Cultivation

Var. lasiophylla is cold hardy; in artificial freezing tests at the Morton Arboretum ^[3] the LT50 (temp. at which 50% of tissues die) was found to be - 27.7 °C. There are no known cultivars of this taxon, nor is it known to be in commerce.
