Barnardia japonica (Japanese Jacinth) [15 Seeds]

(1 customer review)


Germination Information: I recommend these seeds for experienced seed-sowers only, because they require patience while waiting for germination and then while waiting for them to reach flowering size. There isn’t a great deal of information about germinating Japanese jacinth, but I have had good results by sowing 1/4 inch deep in fall to early winter and setting the pot outside, in a spot protected from mice, to germinate when conditions were right in spring. Plant the whole pot of seedlings into a holding bed and leave them there for a couple of years before moving the bulbs to the garden while they are summer-dormant.

All that being said…I have also read that the seeds will germinate (over a period of weeks to months) if started in warm conditions. I leave it to you to decide which route you want to try, with the understanding that germination may take a year or more if you start in warm conditions and then need to leave the seeds out through a natural winter.

Note that this information will not appear on the seed packet you receive.

Japanese jacinth (Barnardia japonica; also known as Barnardia scilloides and Scilla scilloides) belongs to that special group of bulbs that bloom in late summer, like surprise lilies (Lycoris squamigera). I have read reports of its leaves appearing in spring and then disappearing before bloom time. Here in my Pennsylvania garden, however, its leaves pop up in late July to early August, followed quickly by leafless, upright stems topped with clusters of small, pink blooms. As new flowers continue to open through the month, the stems continue to elongate, eventually topping out at about 10 inches tall. Its seeds mature in September to October, after the leaves die back.

Full sun to light shade. Zones 6 (at least) to 9, reportedly. It may tolerate colder areas but hasn’t been widely grown yet, so there isn’t much data on its performance in those areas.

2021-collected seeds sold out. I hope to collect again in mid to late October 2022. At least 15 seeds.
