What are the pros? Hardy -20 deg.F fruits 3-7 yr
What are the cons? Wicked thorns at ground level
I've grown these for 40 years, they've been cold hardy to -20 deg. F. In Jan 1994 lows of -24 F. killed all growth above the snowdrifts, the trees resprouted below the snowline and haven't been harmed since. The largest tree yields 1/2 - 1 bushel of fragrant fruit per year. I have never detected much floral fragrance, however. This species and its hybrids with citrus are used as root stock for much of the worlds cultivated citrus plantings. The trees are tolerant of cold wet soil, they may not handle wet, warm soils as well due to low soil oxygen. Although they tolerate some shade, they grow better in full sun.
Usability of the fruit will depend on ripeness , processing technique, having a tolerance for bitter tastes.The flavor is often described as intensely sour, when the real issue is bitterness. Avoiding getting the bitter rind oil into the juice is helpful. The bitterness is similar to the taste of concentrated grapefruit rind flavors.
Due to the thorns it's not child friendly.
