Seed Amplification of Scotts Valley Polygonum

Scotts Valley Polygonum (Polygonum hickmanii) is an endangered annual species known from a single extant population. With steeply declining numbers of plants in situ and few seeds in storage, we used a close relative to confirm our germination technique and nursery protocols to grow for seed production. We were successful in producing over 90,000 seeds from 100 plants.
