White Pine Blister Rust in NH

The NH Division of Forests and Lands, in cooperation with the USDA forest Service, Canadian Forest Service, Cornell University, UNH cooperative Extension and the NH Department of Agriculture, Markets & Foods has completed a study investigating the infestation of white pine blister rust on immune or resistant gooseberries and currant (Ribes) bushes throughout New Hampshire.  Information gathered suggest the blister rust disease has mutated in the northeast such that Ribes plants selected for genetic immunity to white pine blister rust are no longer immune.  For this reason the Division of Forests and Lands jointly with the Department of Agriculture, Markets & Foods, has removed all immune black currant species from the list of approve plantings.

The new list of Ribes plants approved for planting in New Hampshire with a permit is as follows:


  • Crandall - Plant is often grown for its ornamental, yellow flowers and red fall foliage.
  • Willoughby
  • Rondom - From a breeding program in the Netherlands
  • White Currant 1301 - High yielding, late. From Sweden.
  • Jostaberry - From Germany. Blackish fruits with bland flavor produced on thornless plants.
  • Jahns Prairie - A joint USDA/Ag Canada release. Fruits are red and flavorful.
  • Captivator, Careless, Clark, Crown Bob, Downing, Howards Lancer, Sabine
