I planted an incarvilla in a round bed in my lawn four years ago. It has made quite a lot of leaves but no flowers have appeared. I feed and water it. It does get quite a lot of sun where it is, although it is partly sheltered by a freemontidendron which occupies the same bed. Do you think I should move it? The only other positions I have free are in partly shaded beds.
I believe they like sun but not direct sun iI would have thought the position you have it in would be ok unless the freemontidendron is too close, sorry it isn't much help
I think I would stop the feeding and watering, after four years it should be established and able to look after itself, maybe things are just a bit too lush for it.
Did it ever flower? I have several types of Incarvillea in full sun and they flower their heads off. It will have been grown from seed and sometimes you can get plants that just don't seem to be keen to flower. Sometimes you wonder whether it is worth giving such plants house room. You might as well move it because it is not doing anything useful there. However if you want to give it another try dig it up in the winter and dig down deep. They have a long tuberous root. They are easily grown from seed. If you sow in spring they will flower just over a year later. I have one on my patio that grows to 3 1/2 feet and had over 16 flowers/ spike. I am not sure which specie it is as I have had it for a long time and label went walk about many years ago. I also have Incarvillea maireii, Incarvillea delvayii alba and one called 'Bee's Pink' which is a lovely shade of pink.
