    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.

    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!

    I loved the hyssop. It was a good herb for colds and flu and to boost the health.
