Swamp privet (Forestiera acuminata) is a North American native plant with potential as a nursery crop. There is very little information concerning its propagation. Seeds (depulped drupes) germinated without pretreatment at 22°C to about 60%. The non-germinated portion of this seed lot responded to four weeks cold stratification to induce an additional 32% germination. This combined treatment resulted in 92% germination. Cold stratification of fresh seeds had a negative impact on germination resulting in less than 20% germination. These data suggest swamp privet may have conditional dormancy. Semi-hardwood cuttings were rooted successfully from juvenile and mature stock plants. Cuttings from juvenile stock plants rooted at high percentages (> 90%) with or without an auxin treatment. Cuttings from mature male and female stock plants required auxin for successful rooting and the best treatment resulted in cuttings treated with 2.1 mM K-IBA as an aqueous 3 s quick dip (78% rooting and 6.3 roots). There was no difference in rooting in cuttings selected from male or female stock plants.

Key words: adventitious rooting, auxin, germination, dormancy, conditional dormancy, Oleaceae
