During World War II, a lot of fruits high in vitamin C were becoming increasingly unavailable in the UK. In turn, the British government started encouraging the growth of blackcurrants by home gardeners, since they are incredibly high in vitamin C and were well suited to the British climate.
Blackcurrants were once grown in abundance in the USA as well, but in the early 1900’s it was banned federally due to the belief that blackcurrants helped facilitate white pine blister rust, which was once thought of as a threat the the US lumber industry. In 1966 the ban was transferred to State status and several states have now lifted the ban. However, the ban is still in effect in Maine, Massachusetts, and New Hampshire.
New Hampshire does allow various white, red, and black currant and gooseberry varietals that are immune or resistant to Pine Blister Rust to be planted by permit only. The permit application is straightforward and free, a little paperwork. Nurseries require a copy of your approved permit before shipping into New Hampshire.
