Very diverse habitat. | Wild material | Salix pedicellaris is extremely rare in Iowa only found in the northern tiers of counties. Currently listed as a state threatened plant species and thus tracked via the Iowa Natural Areas Inventory Program (Iowa Department of Natural Resources). Only 15 sites throughout Iowa representing 13 counties have documented S. pedicellaris. Since the year 2000, only two reports (observation/herbarium specimen) have documented the species presence in Iowa. Bog willow is a small shrub (<2 meters) typically with few, short stems often hidden amongst sedges. Spreads clonally via suckering and/or layering lending it to be found in stable fen habitats with ample supply of water that see little to no distrurbance. Spring flowering typically occurring in mid-May to early June with fruiting occurring in early June in Iowa. Little to no existance in cultivation. Leaves are rather waxy and significantly repels water. During a growout of original plant material (sampled as cuttings from collection site in nature) at NCRPIS in Ames, Iowa exectued in 2020, a total of 45 genets were identified as female (14) and male (31) on 4 May 2022 and 17 April 2023 during peak flowering. | 2105808 | Ames 35337 |
