A. Hesse, Weener/Ems, Germany in April 1959." Ames received seeds from Montreal on 7 March 1988; resulting seedlings were entered into NC-7 plant trials. NC7 SUMMARY, 01-Feb-1990: "Thirteen out of nineteen sites reported maintaining this accession through the 1-year trial period; twelve sites reported maintaining it through the 5-year trial period; and only one site located at Waseca, MN reported maintaining it through the 10-year trial period. Winter injury was cited at Chanhassen, MN, Urbana, IL; Madison, WI; and East Lansing, MI with winterkill at Fort Collins, IL; Carrington, ND and Absaraka, ND. Average plant height was 0.90m and 2.70m after the 5-year and 10-year trial periods, respectively. Average plant spread was 0.71m and 2.05m after the 5-year and 10-year trial periods, respectively. The Waseca, MN site commented on this accession's unusual bark. No additional comments or data was received on this accession. No sites recommended this accession because it is neither drought tolerant nor cold hardy." Transferred to NA based on NPGS species priority assignments. | 1498812 | WLP 1622 |
