- AnnaRated 5 out of 5 stars6/28/26Outstanding!
Really easy to start from seed. Two plants survived winter in zone 6a or reseeded. Continous and heavy blooming till fall.

- Jolea H.Verified BuyerRated 5 out of 5 stars6/26/26Beautiful blooms
My rose mallows started blooming a week ago and they are lovely! Their growth increased exponentially once transplanted in large pots outside. Currently, they are about 3 1/2 feet high. I started them from seed about Feb/Mar. I started 3 peat pots and I think it was near 100% germination. I will definitely grow these again. Zone 8b, southwestern Washington state.

Thanks for sharing your wonderful growing experience and for including those helpful details about your zone 8b success! Keep on growing 🌻️
- Margaret V.CA, United StatesVerified BuyerRated 5 out of 5 stars6/12/26Always good.
Germinates at what seems 100%.
I cast the 5 seeds into a 12”x12” foot of dirt that I dug up, fertilized and then raked with my fingers. Then I put some compost dirt on top of the seeds, like a 1/4” deep, watered them using the mist setting.
I kept the foot of dirt wet for several days. Then they got watered by me and my hose whenever I could.
It climbs up whatever garden structure I put it near.
Now the first time I used these seeds, and I have bought 5 or 6 seed packets of these, it was a crazy disaster. I used no restraint. I put all the seeds in my hand and threw them onto the 8’x30’ area with such wonderful “chaos” gardening. I felt like I had arrived. But I didn’t prepare the ground. In several years of this, I learned that without watering them, they will not grow. Those days when I was still trying to cast a pack of seeds, I learned about dirt and soil, and plants that climb and plants the hang, and more. I guess I still don’t read the packet. I just learn a lot every year.
These are beautiful flowers, and they don’t disappoint. Just make friends with one or two plants every year. I’m a good gardener now, measured by how hard I work, and plants I grow. By the happiness I feel when I walk under my pink mallow trellis.
