No way to insure it as there are simply too many variables but from what I have read Group VI (your variety) is approx. 2.5 to 3 weeks between pod formation and maturity. However if your plants are already 6' tall something is out of whack (likely insufficient sun or over-crowding) and that will delay them more. See article below for more details and all the variables that affect it.

Hello Mad Woman, I would say 20% is a little low. I'm at around 50% now and expect to drop to around 30% after it gets really hot. I suspect the cause for your low rate may be that your plants are still fairly new. I have had lots of plants that won't set a pod until they've been established for a couple of years. I've never used the term HOT pollen, so I'm not sure. It's ether very fertile or from a flower you accidentally broke off at the Hybridizer's garden and took home with you! ;0) I think you're probably right; fertile. I have seen very little to even suspect stray pollination, so I don't go to any extra steps to eliminate the possibility. I know some people do remove the sepals and petals and the stamen with them, but that's to keep the pollen away from the bugs and bees that steal it, and make the flower unattractive. It is still easily to pollinate the pistil. Looks like some nice crosses you have made. The dip to tet cross will result in a pod, but in time it will dry up and fall off. I sometimes pollinate a tet with a dip to set a pod, getting the tet in the mood, so to speak. Sometime it works and it will start taking tet crosses. Good luck, sounds like you are doing very well.

Wow! Ya'll are sure worrying a lot over these moon vines! I had never heard of putting peroxide into the water with the seeds before. I let mine soak for 2-3 days, when the weather is warm outdoors, then they grow like weeds! They get the occasional shot of miracle grow with the rest of the garden, but other than that, they just grow and bloom like they're supposed to. It sounds like ya'll must be in a colder zone. I'm in zone 7b.

There are three species of moonvine (that I know of) that are pink or lavender. Ipomoea turbinata - lavender I. muricata - pink I. macrorhiza - pink; from the pictures I've seen, looks much like I. muricata, not sure what the difference is. I'm growing the lavender this year. It's interesting, but as Arum said, the flowers are smallish. I had traded for a pink variety, but didn't get them planted this year. The seeds were cool though - they were covered in "fur"!
