Saucer Vine

1 out of 5 stars Jul 3, 2019
NOT ONE seed germinated. Very unhappy.
Rory Garza from FL
Owner Response: Hi Rory, Thank you for contacting us about this issue. We are so sorry the cup and saucer vine didn't germinate for you. We test our seeds regularly using an independent laboratory to make sure they exceed industry standards for germination, along with our own, which is why we are able to guarantee our seeds. The last couple of tests resulted in 96% and 93% germination, but this species does need a few tricks to get going. We will be in touch soon to see how we can help.

Worth it

A little effort & patience with these seeds pays off. They're growing quickly & beautifully climbing up some lattice.
Lauren from NJ

Stunning blooms!

A little stubborn to germinate but once they take off, they are worth the effort. Start extra early if you have short season.

Great germination rate with a few 'tricks'

5 out of 5 stars Mar 17, 2021
I planted these seeds February 8th it's March 17th and they are growing strong and healthy, going on 7+ inches now! I did score them on sandpaper, soaked them 24 hrs and made sure to plant them vertically (so not flat side on soil) and had a 100% germination rate. Started clipping the shoots/tendrils back to have them grow more bushy rather than long. I know it's too early to plant them out yet, but I was so excited about how well these are doing I wanted to share here to encourage others to grow them. Bees and hummingbirds love them, they are gorgeous, so what are you waiting for!

All vine, no bells

4 out of 5 stars Jul 13, 2021
Reached the end of my 60" trellis quickly and climbed over it. Two plants out of the entire packet germinated and survived. Not a single bloom, yet, but definately not dead at least. The two plants look different, presumably one is significantly more sunscorched but its a pretty red rust color so that's cool.
Owner Response: Hello, This variety normally blooms beginning in mid-summer (August), so they just need a tad more time, unless there is an overage of nitrogen which will delay flowering. Happy gardening!

Great germination

5 out of 5 stars Oct 23, 2021
I had near 100% germination with these. They do like a protected location best. I planted a handful of vines and any exposed to wind didn't do too well. The one climbing up my front porch has done amazingly and is still flowering through a handful of frosts thanks to its protected spot.
Amy from UT

beautiful but too all season to bloom

3 out of 5 stars Nov 21, 2021
The seeds came up just fine and vines seemed healthy but I only had about 3 blooms that were very late in the season? Maybe not suited for zone 5b?
Cathy from IL
Owner Response: Hi Cathy, These vines do take a while to mature which can be a challenge in short-season areas however your zone (which indicates your average coldest winter temperature) won't impact these since they are annuals.

Germinated very well. Survived neglect well. Didn't transplant in time for flowering
Marie from WA

50% germination in 2 days!

5 out of 5 stars Feb 20, 2022
After an 8 hr soak and then a 1:5 peroxide rinse, half the seeds germinated overnight - moist paper towel, in dark, warm spot. I fully expect a 100% germination termination after 3 days.
Carolyn from CA

Late blooming

5 out of 5 stars Mar 2, 2022
Started indoors, moved to larger containers before transplanting outside. They were lush, vigorous climbing vines. However, they didn't start blooming until September. Bloomed September until November. Gorgeous, fascinating blooms if you can wait for them!
Robin from VA

Not so good

1 out of 5 stars Mar 21, 2022
only 2 seeds sprouted out of entire packet. One seedling does well, the other is still straggling. Very disappointed.
Natalia from MA
Owner Response: Hi Natalia, We are sorry you had difficulty germinating these seeds. A customer service agent will reach out to you by email to help. They are tricky and you can find some specific tips on the seed packet. We are always happy to help troubleshoot issues. Rest assured, quality is very important to us and our seeds are tested frequently to ensure germination rates meet federal and our own standards.

great germination, but did not survive transplant

3 out of 5 stars May 27, 2022
I had great germination and strong seedlings, but they did not survive transplant in 3 different locations. Have no idea why not.
Jessica from ME
Owner Response: Hi Jessica, I'm sorry your seedlings didn't make it once transferred. It is important to allow your plant to acclimate for 7-10 days before transplanting to reduce transplant stress and the chance of sunburn. Please reach out to us for help whenever you would like.
