    Customer photo review of Sweet Pea Seeds - Royal Navy Blue

    I ordered this seed pack & the burgundy seed pack and I dont think these seeds germinated at all. If they did theyre not the colors as expected as I only have light purple, light pink, and scarlet red flowers blooming. Not a deep navy color.

    I purchased these in this color specifically because it is very unique, the sweet peas that grew from these seeds were more of a light purple.

    Customer photo review of Sweet Pea Seeds - Royal Navy Blue

    These had a hard time starting as the heat was early this year and in the 80s when I planted these in May. Now that it’s cooler during the day and in the 50s at night. These are beautiful and taller than I am, pushing 6 feet tall!! They smell heavenly….I’ve planted sweet peas a few times over the years but never had any grow until I purchased these seeds from Eden brothers <3
