I started several plants from seed Spring 2025, they are finally blooming this week in South jersey (zone 7). Great germination and easy to care for.

- Russell G.Verified BuyerRated 2 out of 5 stars10/30/25Seeds did not sprout
Planted half of the seeds after dividing the total in half. Will plant the other half in the spring. Of those planted, I lightly sandpapered half, soaked the other half for 24 hours. None sprouted.
