gakaren asked me to post a picture of my "blacke"
sweet potato bloom.
each time, I have bought a starter plant of this.
after summer, brought it inside (pruned back) under plant lights. in the spring put it back out.
yes, it looks ratty.
ta da....it blooms! I have kept one plant for over 5 years...

2nd

well how about that!! beautiful blooms too. Never saw one bloom before...maybe it's because I always consider them an annual and let the frost kill them. So you save your vines from year to year? I tried saving a tuber one year, unsuccessfully, I might add.

Thank you so much for sharing this.

TFS. I wondered if anyone ever got them to bloom. And if anyone ever brought them in for the winter. I have the green one and might try to bring it in.

I always get some purple and some of the green/chartreuse color. I've had the purple ones bloom, but never the green ones. Have you?

never the green ones

Thank you Phinny!

I have 2 of the ones like Phinny's and had them in hanging baskets...they both bloomed this year. But the blooms are small & were only there for one day & then fell off. And they were all kind of hidden in the foliage.
I have another plant with the heart shaped leaves, same color and it hasn't bloomed...and neither of my light green ones have either.

they are related to morning glories.
so the bloom only lasts a short while.
they are beautiful though

I've had blooms on my dark purple vines but not on my green vines.

That's pretty! I need to get some black and green plants.

Pretty flower! I've never had them bloom, probably our season isn't long enough.

joy--just bring the plant inside. I cut mine back to less than 1 foot, and bring the whole pot in.
you could try it, the flowers are well worth it.mine is under plant lights from october to april

OOOHHH thanks phineas. I cut both of mine back last yr. and saved them. That's what you see in my pics. I jsut kept them in water. I'll save some this yr. but not in water all winter!

I just bought my plant this year and it is blooming like mad and I am in zone 3. So apparently it has nothing to do with age.

The blooms were under the leaves and I only noticed them when I moved the leaves to water the container.

really I haven't had any under two years bloom.
were yours small when you bought them?

We don't plant till June but with the warm spring I am sure the nursery plants were larger than normal but I would not call them big.

My SIL, in the next town over, has the same plant, bought at a different place and right now it is much larger than mine and it has no blooms. Go figure!!

Phinny mine that bloomed this year were small ones I got at Lowes. They have quit blooming now since I changed my pots and moved them, but they are still growing.

maybe metwo...
you just have it in a better spot!
oh, and SKILL! LOL
