Germination is going good. Beautiful packaging with great details. Set these out for winter sowing to aid in Germination and most came up. Excited for more spring growth.

- Barbara A.Verified BuyerRated 4 out of 5 stars2/13/26Good germination
Way too early to give an overall review because seedlings are just an inch high. However, the germination was good. Put seeds on a damp paper towel in a zip lock bag in the refrigerator for one week before sowing and was happy with the germination.

The first time I planted the Delphinium, it was in the hot part of the spring already and I chalked it up to me planting too late in the season or in the wrong season altogether. So I planted them again 2 weeks ago and nothing has sprouted yet. The package says 15-20 days so hopefully within the next week or so I'll see something. As of now, I'm not sure how confident I am in the Delphium. (Pacific Giants Blend) Also the Golden Bell Peppers did not sprout at all. I planted 4 or 5 of them in the spring and none of them sprouted.
