Passion Flower Jewelry

I have a 400 jeweler and I've been trying to discover all my recipes. I've accomplished this except for two jewelry lines: the final mithril passion flower set and the orichalcum passion flower set.

Each piece of the mithril set requires 3 embellished brilliant passion flowers, each of which requires 5 passion flowers, for a total of 45 passion flowers to discover the entire line.

Each piece of the orichalcum set requires 5 exquisite passion flowers, each of which requires 15 passion flowers, for a total of 225 passion flowers.

I have already farmed the mithril and orichalcum needed, but the passion flowers are another story. I've been farming Southsun Cove for 2 weeks now. The first week I didn't get any passion flowers and the second week I got 3. If I could be guaranteed 3 passion flowers every 2 weeks, it would take me roughly 3 years to farm enough to complete my jewelry lines. And, of course, I can be guaranteed no such thing.

The only other avenue I know of is to buy the passion flowers. These are selling for 50-55 silver a piece on the TP. In order to buy all the necessary passion flowers, I'd need to somehow get 135 gold.

Or am I missing something obvious here, like there are more places to farm passion flowers and I've missed that memo? Anyone know how I can efficiently accomplish this? Thanks. :)

Passion flower's are extremely hard to get, as you probably already know!

The best bet is to slowly buy them off the Trading post over a couple of months or possibly wait in hope for a patch increasing the drop rates.
