    Customer photo review of Zinnia Seeds - Benary's Giant White

    Beautiful flowers. Literally have never grown (or tried to grow) anything from seed before. Also I am a SUPER beginner. I chose to try out a potted cut flower garden and used one seed in this pot. From that one seed so far I have a nice big bloom, one about halfway there, 4 buds, and what looks like 6 more potential buds within the next week or 2!! (In zone 6 FYI)

    Customer photo review of Zinnia Seeds - Benary's Giant White

    I reviewed this before, but as the season has gone on I wanted to add more pictures and I wasn’t able to edit my previous review. These are stunning and so full! They are beautiful and larger than some of my other zinnias. I will say they do not last as long in a vase as some of my others, they tend to get brown tips in a couple days, but they are beautiful.

    These are coming in very well and are a pretty contrast to the green in my garden. I like how full/round the blooms are. I would definitely plant these again!

    This is my first time growing zinnias (zone 9a, very humid) and these have been amazing. I have an entire 8x2’ raised planter that is full of these amazing flowers. I bought one seed packet and sowed as directed, and they started sprouting within days. I planted about three months ago and some of the flowers are almost reaching 3’ above the planter. The bloom size varies but I have had a decent amount that are large. Some look exactly like the product photos, but other are more open with visible yellow stamens. I direct-sowed them and after they sprouted a transplanted a few to spread them out. The ones I transplanted have struggled, they are less than half the height of the others and have produced small blooms. They seem to do very well when direct-sowed and left alone. I’ve trimmed lower leaves for airflow and have had issues with snails but these plants are thriving, even in all-day blazing full sun and intense heat. They last forever in a vase with plain water and are so abundant that I’ve been able to gift some bouquets to others. Definitely buying more colors next year!
