Passion fruit saplings

My neighbour gave me 3 stalks of passion fruit from her plant - it seems that they can grow via stem cutting. I left them in a bottle of water for 1 week - they are really growing... no roots in sight yet - guess they are growing because there is water supply to the stem.... It is starting to sprout as you can see from the picture below... Also, near the edge of the leaves, there seems to be some liquid secretions... wondering what's that... it is a bit sticky.... I hope the roots will appear soon so that I can transplant them... But anyway, their plot is not ready yet!! Still changkoling away this morning .... I am dead tired from all the changkoling this morning......... hopefully no aches tomorrow!!
