Sold out  Seeds of the Shiawassee variety.

Shiawassee more than other Jerusalem artichoke varieties produces a greater amount of full seeds. The seedlings from this group are usually white colored with a long carrot like tuber with some reaching up to 12 inches long. From seed, this selection produces offspring similar to the parent. Some variation is naturally found in the length of the tubers and red ones are produced once in a while too. That in itself is kind of rare and fortunate so you can essentially breed your own selections quickly. 

The seeds germinate easily but it is best to moisten them in a very light sand mix and then refrigerate for a week. Once you remove them from the refrigerator the seeds will sprout within a week or less. Sometimes you might want to repeat this procedure if a few are stubborn. This cooling and warming effect will unify the germination so more of them will all  sprout at once. Use a well drained soil mix and cover lightly so just enough soil holds the seeds in place or use a light sprinkling of sand. 

The seeds we offer are from 2020. A cut test is 75% solid seeds.
