Bottle Plant Yellow Do you like flowers? Then we recommend this tropical bottle plant (Jatropha Podagrica)! Because if you water and fertilise this eye-catcher in its growth-period you’ll be spoiled for flowers for the rest of the year! The plant gets its name from the peculiar shaped stem which looks like the top of a bottle. The stem will thicken each year and new flowers will appear. Taking care of the bottle-plant is very easy!
