Really having a hard time locating this beautiful flower. Does anyone have any ideas where I might find them?

There's a few 5 packs of seed on eBay, and I found one or 2 live plants there, about $40 each, and look pretty small, the seller has good reviews but I've always avoided them for several reasons, over priced, reselling plugs from wholesale suppliers, and generally not the best looking plants, their Chilean bellflower looks ok, I guess, I'm not experienced with that plant.

It seems they are in peril in their native range.

Looks like they stock them too but are overseas

Hi! I have a Lapageria rosea, (Chilean bellflower) that has done just OK in my garden and I now have more time to devote to making it flourish. I have read that it does not do well when 'lime' is given to the plant. I recently realized that perhaps lime means calcium carbonate. I know that my water supply is hard and probably contains high amounts of calcium carbonate. So am concluding this is a culprit holding the Lapageria from doing better. I also read that adding small amounts of vinegar to water (1 tsp of 5% per quart water) will provide a more acidic environment.
Does anyone have any experience with Lapageria and can comment / make suggestions on the above? Plant background: its about a 25-30 year old in the ground vine. Produces flowers every year, the vine is 'scrawny' at best, not really something you would expect with a 25+ year old vine. Its root ball was planted in clay soil, but a large hole dug first with organic amendments. And is in moderate to heavy shade. The vine is in moderate shade with lightly filtered sunlight. Its located in the San Francisco Calif Bay Area. There is new growth every year, but not a lot. Hoping someone can make suggestions. Thanks for helping

I got some seed from Top Tropicals in FL earlier this year. I planted 5 and only two germinated. I gave one away and the one I kept is about 6" tall now.

@ardesia remember all those seeds I got from TT? Only TWO out of about 20 packs pf different seeds germinated. I have 2 Delonix regis seedlings. Nothing else took. I was so disappointed. I wonder if they were too old

Pretty much the same here, very few germinated. Old or not kept under good conditions, who knows.
