The suaveolens types open the widest, but they are usually only flared wide at night and kind of closed during the day. Check out Morgensonne, Delta Dawn, anything with suaveolens genes....

thank you! that's tremendously helpful :)

Ria

Insignis has the widest flowers.

If you find one get me one too and I'll pay you $500 for it.

Here is a link that might be useful: Insingis

I'm not sure I'm understanding the significance - there are a ton of insignis for sale across the internet. do you mean a wild pure one, or something?

Ria

Ria,

Most, if not all, of what are claimed to be insignis are actually Suaveolens or Suaveolens hybrids.

I am not sure why these plants were considered Insignis in the first place.

Did you check out the link in my post above?

This is now what's thought to be typical Insignis. The corolla tube flares quite wide, but is normally folded during periods of lower humidity, and those long graceful tendrils that point downward are also a sure sign. Also, the calyx is longer than Suaveolens and the leaves are long and narrow.

I've provided a link to some more pictures below.

I also forgot to mention, not only is the calyx longer than Suaveolens but the corolla tube also extends further out of the calyx.

Here's another link to a pic of a white one below.

really now! I'm so glad you posted that link! tropicalgardener1 commented that they grow wild in toro negro - I'm going to puerto rico in july, so I might actually be able to help you out with a wild specimen.

I'll be going for my boyfriend's sister's quinceanera (at least, that's why my ticket has been purchased for me :P) but I plan to spend the entire week in the jungle, heh! let me know if there's anything else worth looking out for and I'll do my best. the prospect of this trip just got twice as exciting!

Ria

Thanks Ria.

I am in contact with him already. Hopefully he will send me some pics.

The only things I have heard of growing there are Suaveolens and double white Candida's.

But it would be awesome if there were some Insignis.

Either way. take lots of pics!

I certainly will! I'll be bringing my rebel no matter how much of a pain it'll be to travel with, heh, and my itty bitty acer so I can upload photos and pester everyone for IDs, lol. I've also been reading up on what kinds of passiflora are native to the region - I've always had a keen interest in them.

also I just realized how odd it sounds that his sister is so young. LOL. no, I'm no cradle robber - they're almost ten years apart :P

Ria

He's only five?! LOL

Matt... that's a great flower. I love the slender tube, in relation to the rest of the flower... and the flower seems really long, in relation to the calyx. Very pretty. I can see why it is so prized.

Bob

ROFL BOB. well played. XD

I was admiring those particular qualities, too... I really hope I find some native pretties of the flowering sort that I recognize :)
