    These true hyssop seeds pay off the second year. These two plants on either side of my little walkway are about 36" tall, and now in July (Zone 8b) their blooms are hitting their stride!

    Great plant! Very underrated in my opinion. They grew slowly at first but they eventually became much bigger than I thought. Very easy plant, quite drought tolerant and the flowers are beautiful. Bees and butterflies love them. The smell is so nice too. I didn’t have any problems with germination. I think sowing the seeds and leave them outside around late Winter really helped because of the temperature fluctuations.

    Highly recommend this plant!

    I winter sowed these in February of 2023. Planted in a milk jug and left outside until early spring the germination rate was pretty good. Transplanted to the garden in April and have bloomed nonstop since. I love these.

    These seeds. Including many other flowering seeds, germinated quickly! I started them indoors to be able to provide food for the hummingbirds when they arrive again.
