I'm trying this sweet potato this year... not very many plants, as we haven't tried to store them before.
Anyway, we have a lot of wild morning glory here, and I have a sweet potato question... can these cross? And if they can, will it affect my slips for next year? The only other time I grew sweet potatoes, I had only a minor yield, and there were no wild morning glory plants nearby, so I never really thought about it...

Lav, in his book, ( Sweet Potatoes for the Home Garden with Special Techniques for Northern Growers, Green Spade Books, Kingston, Ontario 1998) Ken Allan speaks about Morning Glories in mass-selection breeding programs to produce flowering in non or poor flowering varieties of S.P's, so I'm going to guess that if they cross, it's not a really big problem?
Also, did you know that there are 1,000 species in the Convolvulacae family and that SP's and Water Spinach are the only two used as food. Bindweed and Morning glory are probably the most common.
BTW, the Asian Purple varieties are very tasty IMO
Hope this helps.

It shouldn't affect your slips only the seeds, I"d imagine, if they do cross though I would think that would be a wide cross so not terribly common.
I second Ken Allan's book as an excellent resource particularly for far north / short growing season locations.

It depends on what species of wild/feral morning-glory. Some wild morning glories are actually feral sweet potatoes (hmmm, these could be valuable...). But many belong to different species (less likely to cross) and even different genera (extremely unlikely to cross).
IN NO CASE WILL IT AFFECT YOUR SLIPS AT ALL. It would only affect seed.
>>zone 9a/SWGB zone 7
Is that "sunset western garden book zone 7"? Willamette Valley, Rogue River Valley, foothills of the California coastal range? If it rates a 9a you're probably south of Oregon, or at least as far south as the Rogue River Valley. There's actually a native California Ipomea, but it is rare, and I would guess your wild morning glories are actually Calystegia sepium var americanum. Look at the leaves. Are they "arrowhead shaped" or "heart shaped"?
Okinawa Purple almost never produces seed anyway. It rarely blooms. Debbie Falkenberg of Mericlone Labs says she only carries it because people ask for it. She thinks there are better, more vigorous purples. I'll be able to evaluate some of them once they tuberize for me. Okinawa purple is sluggish and not very productive.

Okinawan Purple is a very long season sweetpotato with 140+ days to maturity. It is relatively low in production. Tubers do not store well over winter and large tubers almost never sprout.
Gather tubers 1 to 1.5 inches diameter to save for next years sprouts.

lav, we're trialing the Purple Okinawan this year also. so far so good. we're also growing Korean Purple, Purple, and Uala. i was planning on saving slips of each to overwinter for next year instead of seed.

I embarked on a search for morning glory relatives that would form tubers a few years ago. My interest was in finding something that would grow tubers from seed. I found a couple.
The problem I ran across in growing morning glories near sweet potatoes is that morning glories serve as reservoirs for a variety of diseases that will infect sweet potatoes. I have not read Allan's book (it is impossible to find) so I don't know what he says about the disease issue.

I wish bindweed would cross with sweets so gophers and voles would eat the stuff!

Hello I live in Barbados and am very interested in growing this sweet potato. We grow the red and cream skin types. It is very difficult to bring in plant material without a permit however seeds will be easier. Do these potatoes seed?

I would expect that most sweet potatoes will produce seeds in a long season area like Florida or Puerto Rico, I don't know if there is a seed company that would carry them although B&T World Seed Co. Speaking of morning Glories there is a wild white flowered one that has a large deep tap root that comes back from the roots. I have no way of knowing if it can cross with sweet potatoes or if it can be used in a breeding program. Its pretty rampant growing into the tops of twenty foot trees.
It would be great if it could be crossed with a edible sweet potato that way you could have them come up each year with out having to plant them each time.

If it's the one I'm thinking of, the root on that morning glory is edible. |

So who can recommend a good variety of purple sweet potato?....it can be long season, no problem. I'm planning on next year and Patty likes the purple ones. John |
