Hi FW - I had the same problem when I wanted to post a photo and actually had to go through the other GW forums to see how other people did it. I then subscribed to Photobucket, which allows you to upload photos to your account (free) which in turn gives you a code to paste into the GW forum message. You don't actually insert the photo to the message, just the code. Photobucket actually hosts your photo via the code. Once you've used it a couple of times it is quite easy. It is a pity there isn't a similar feature in GW - as you say.

Thanks for the help, everybody. I reposted this thread with pictures of the flowers in the Name this Plant forum. I'm sorry the pictures aren't ideal. This plant is somehow hard to capture with a phone camera. Here's the new thread: http://forums2.gardenweb.com/discussions/3251535/m=23/please-help-id-this-plant-coffee-plant

pigface. What a name! It could also be senecio radicans I think it's sometimes called string of bananas or something like that.

Salvia penstemonoides has larger calyxes, a square stem, sessile upper stem leaves and a lemon/lime fragrance. Salvia penstemonoides is very rare, and was once thought to be extinct. Though this plant does resemble Justicia spicagera,(Mexican Honeysuckle), this plant has long petioles, whereas Justicia spicagera has winged petioles. Compare with Dicliptera sexangularis, Acanthaceae. Dicliptera sexangularis has been classified as Justicia assurgans in the past and one of it's common names is False Mint. https://www.flawildflowers.org/flower-friday-dicliptera-sexangularis/
