    I received them really quickly for the distance they were shipped. Just planted them a week ago though so I can’t attest to the seed yet. No reason to think they won’t grow.

    The package arrived when expected. I really like that the labels include info for planting times/depth and a picture. This makes it much easier to organize and design my flower bed! I just planted the seeds yesterday.
