It's December here. Have to

"It's December here. Have to wait and see"

— Pamela B. (5/5)

Good germination rate

"I started these seeds last year, and again this year. The ones this year had become quite leggy, I think I started them too late for the season. But the ones I did last year are doing amazing! They came back and are looking beautiful. I love these seeds!"

— Anastasiaf20 (5/5)

Can’t wait to see results!

"Im super excited about this flowers! I just got them a few days ago and planted them yesterday so we’ll have to way a few days until we see results but I can’t wait. The planting and growing instructions were super clear and easy to follow, the packaging quality was excellent since it got a little wet on the outside but the seeds were perfectly fine inside. I’ll update one I have results!! 🥰"

— Javierahl (5/5)

Excellent germination rate.

"I started my seeds in an aerogarden. I used 12 seeds with 100% germination rate. The problem was I didn't appropriately harden them off, especially this far into summer and they didn't make it. Will use additional seeds and start in my aerogarden next February. This is a great brand that I have great results as the 100% germination rate is rare."

— Amyr328 (5/5)

Cute little flowers

"These are such cute little flowers! Can’t wait to see how they add a pop of color to the front yard. Seeds were easy to sow, and they germinate in 10-14 days!"

— Oliviah1f71 (5/5)

Mid summer garden

"Unfortunately I don’t have the luxury of waiting for my black eyed Susan’s to bloom before reviewing due to the short window. Package suggests 84 days from planting to growth. Still I look forward to having a welcome place for pollinators, not to mention the lovely sunshine of a side garden. Easy to plant and quality instructions on the packaging."

— Laceyn17 (4/5)

Great seed brand!

"We purchased a seed growth kit to start these FERRY-MORSE THUNBERGIA Black-Eyed Susan seeds and have very high hopes for successful flowers! We have purchased this brand in other items before and have had great success! The packaging is great, the seeds look great, and the value for money is fantastic! I hope to update this review as we see more progress!"

— Cassandrad52 (5/5)

So many seeds!

"I got the Ferry-Morse Thunbergia Black Eyes Susan Seeds. The packet came with a large amount of seeds, around 30, which I planted in my backyard garden. I can't wait for them to grow! These plants are great for attracting pollinators to my yard, and have beautiful yellow blooms."

— Steph091209 (5/5)

Really hoping they germinate and grow!

"I don't have a green thumb but I love flowers and have always wanted these in my flowerbed!! They're so pretty! I've planted them but nothing has happened yet. I am really hoping something sprouts I've followed the directions 🤞"

— Katwarner3 (5/5)

Easy to plant, no green thumb needed!

"Easy to plant, and low maintenance once they are. Watered regularly with my other flowers and can’t wait to see these beauties! No green thumb needed, great to use as starter flowers for garden."

— Kellyp2789 (4/5)
