searching for seeds of Antigonon leptopus alba

Hi, am wondering if anyone here may be able to help me find seeds of this one. (white queens wreath aka coral vine)
..did post on the seed trading forum with no luck (have tried a couple times)Dale a gardener suggested posting here says there's a couple big ones growing at Ft Sam botanical gardens in san antonio which produce seed..if someone here is able to help it would be much appreciated ...as I would dearly love to find it...have been unable to find it here ...I have lots of large flowered canna seeds to trade also podranea and pink pandorea .I am also searching for orange Jubilee aka orange tecoma ,I have the yellow version tecoma stans.Thanking you.

I not sure they would trade, but may have seed for sale, good luck

I know where I will be able to find the seeds when they ripen. It is a little early for them to do so now. They germinate very quickly.

Hi lulu,I had a look but it doesn't appear they do....thanks for the info anyway.Thankyou also htop,when would be the best time for me to search again on this forum?.I have the pink one and love it ...I thought the white would look good growing with it.

I will send tou a D-mail when I find some seeds.

Thank you so much...that will be wonderful!
