|Sweet Potato Blossom|
So my first thought, "I want to collect the "true seeds" they will produce, and then next year just plant the seeds rather than starting slips ".
It turns out that if the bloom becomes pollinated its seeds if planted will not be true to parent, or will grow "junk" tubers. Just like if you plant the seeds from an apple core you may end up with 1 in 100 or 1 in 1000 that makes a good eating apple similar to it's parent. This is why apples and so many other plants are propagated with cuttings, grafting or in the case of sweet potatoes, slips. For now I will stick to growing my own slips for sweet potatoes, but I will enjoy the blooms when they come.
