In winter, you might just want to set it in front of your balcony doors. I'm assuming you have some sliding glass doors that open onto the balcony, right? You'll probably have to cut it back some to bring it indoors, and provide it was something to climb on as well. Three stakes set in the pot like a "wigwam", should work just fine. It will probably slow down it's growth during that time anyway. Now, don't blame me if you coddle it so much it wants to climb all around your living room, up over the curtain rod and around your furniture! LOL! Passion vines are vigorous vines IMHO! I planted a 3' P. caerulea about 5 weeks ago and it is already about 12' long! Your incarnata is probably going to behave a lot like mine. Once the weather REALLY heats up, it will take off. Until then, it grows in small spurts. Mine is up from the ground about 4-6", but as the weather gets "consistently" warm, it will take off like a bat out of....well, you get the picture! You may have to give it a good size pot eventually - up to 16-18" at least because I think passifloras have a good-sized root system. Just follow the plant's lead on that. Once you see roots peeking out the bottom of the pot, it's time to give it a larger pot. Got from 4" to 6", and then from 6" to 8", and then from 8" to 10", and so on. You may be able to skip a size and to to the larger pot, say 6" to 10" with this vine because of it's vigor. Just don't overwater it then. My passi leaves droop when they need water. Passi's are good at conveying to you what they want and need - much better than some plants. Passi's like lots and lots of sun, so give it the most sun exposure you can. They will take some shade, preferably in the late afternoon or evening. My gets shade from the West sun, and it does fine. Probably doesn't bloom as much, but if I do get buds, the Gulf Frits usually eat them anyway, so it's no big loss to me. Hope this helps! Susan

first off ... resins idea of winter is about 40 degrees F .... so anything on a windowsill will do just fine ... cool and bright ... in my z5 .... with winter hovering around zero .. [both C and F .. lol] ... ANYTHING YOU PUT ON A WINDOWSILL WILL DIE .... especially if it gets frozen to the moisture on the window ... once you move the plants away from the window ... you have little or no light that is intense enough for the plants ... ergo .. supplemental light is requisite .... i dont understand why you are having so much trouble with this???? plants need 4 things... LIGHT .. WATER ... FOOD and MEDIA ... master them all .. you you will grow things... omit one.. and you fail .. i am simply talking about the light needed for the plant to maintain itself ... most houseplants.. are tropical in origin.. and under-canopy plants... that can 'live' in the low light found indoors ... conifers are basically FULL SUNLIGHT plants ..... with a few exceptions .. so you are starting in a big hole.. if you dont add light .. you can go to both extremes in making a light system ... in my experience .. hosta, annuals and rooting conifers indoors ... the $12 light fixture ... with two plain lights.. run 16 hours per day ... is about as cheap as you can go .... no special bulbs are needed ... and the plants should be about 2 or 3 inches from the light .... personally .. i know nothing about the rarities listed by resin .... all i do know is that plants need sufficient light .... now.. once you have enough light.. lol ... you will have to figure out how to keep water from drowning the plants ... since you humidity is so high .. since.. most conifers are not swamp plants ... they need water.. but they dont like wet feet .... and that is all wrapped up in the media.. or potting soil .... #3 .. i would never fertilize a conifer .. unless it had been in the pot a year or two .... and i would make sure that the media does NOT have fert in it ... light.. water.. food .. media ... now go do the right thing .... ken

I know that this is old, but a couple of addenda for those running across this in a Google search: you can actually coat over glossy paint with flat, but you first have to sand the glossy paint until it's dull (thus creating a porous surface that the new coat of paint can stick to), or use a primer that will stick to glossy paint. The primer rickyk22 is referencing is probably Bullseye 1-2-3, which does indeed do a good job of sticking to gloss (I've tested this up to semigloss). Latex paint will hold up on a windowsill, but a high quality paint is recommended for anything that's going to take regular wear - aside from the issue of pulling paint off, you may notice lower quality paints flaking or cracking due to humidity, UV, and temperature changes from the window. Glossy finishes will be more resilient to this than flatter ones.

Just seeing this. Did you have any luck with Passiflora? A really good vine for indoors that has amazingly scented flowers would be Stephanotis.
