I haven't planted these outside as of yet.
I've started some indoors and every one of them germinated and they're growing well!

- Addison y.Verified BuyerRated 5 out of 5 stars3/12/26Amazing seeds
These were so easy to start, amazing germination and they have been so easy to tend to. They are lush and doing so well. Highly recommend starting dahlias from seed. Way lower cost than tubers and an early kick off to my short growing season.

Still waiting for seeds to germinate but I was very surprised to only find 19 seeds in my package. The way the description states the seed count I was thinking I’d have closer to 50 seeds but not 31 seeds less than 50.

This morning (Tuesday), I noticed several broad leaves on the dahlias in my trays, which I planted on Friday. I've never grown dahlias before, so this is exciting!
