Very healthy looking Aeschynanthus Lobbianus.
Yes - you can reroot the pieces - they will grow roots from the leaf nodes - so make cuttings, they can go as short as 2 nodes, remove the bottom leaves and stick them into the loose soil - like for AV - and they will root. You want to enjoy the bloom though - they bloom for months one bunch of flowers after another. They need the same or more light as AVs, they like to be potbound and mature - means = just let it be.

You will enjoy this vine a lot - just do not get too upset when it will start dropping the spent flowers on the floor. If they get pollinated - they develop a long skinny seed pod - I had one 15" - then they crack and miniscule seeds have long hair to travel with the wind.

Thank you Irina. I'm keeping this plant outside, hanging it under a small three together with some hoyas. So it's getting 'dappled light' all right. But we're now approaching the rainy season. I wonder if I should bring the lipstick inside to avoid getting water-logged or not?

No - just be sure that it has a really good drainage and water flashes through. It is a native plant.

You can get some cuttings and start them inside just in case.

Cuttings root very easily--probably even easier in your climate than in the temperate zones. Aerial roots make it even easier, as you have a head start. Potting up lots of cuttings together makes a really nice full pot. If you want, you can start lots of new pots and have them hanging everywhere. It sounds like you have a large mature plant for the size of the pot. So, I suspect it will handle the rainy season well. They do like a lose epiphyte mix, similar to a hoya.

Thanks irina and jon.
I've already put some cuttings to root. The vine was so brittle that one of them 'broke' when I tried to 'get it to behave' (you know what I mean - LOL). I planned to have some more pots as you suggested. I'm thrilled to see if they will flower for me in time.
Jon, does this plant have a flowering season? Or does it flower all the time? I saw different pots at the vendors, some flower some don't.

A little used term I would apply to it is a "chronic bloomer", meaning it will go in and out of bloom, with no specific season. I think it, therefore, may have two or three flowering periods during the year. They take a long time to develop the red corolla, but the colorful dark calyx colors up for quite a long time before the corollas emerge, so the effect is that you will have color for much of the year.

Thanks Jon... that's good to know.
Have a nice weekend. (It's Friday in Vietnam already!)
