It *may* be it's getting too much nitrogen & not enough phosphorus.. Nitro = lots of leaves, phos = more blooms.

Since there's some rabbit "presents" in there with it I'd let it go- The more it grows the faster it uses that up (and yes the bigger it gets) but eventually as the N level drops it'll start to flower.
At least I'm pretty sure that's what'll happen.

I feel your pain tho- Some of mine haven't bloomed for 2 or 3 years. Not sure they ever will.

Krstofer's right. Many passiflora have evolved to thrive in poor soil, so when they get abundant fertilizer, they go nuts with vegetative growth at the expense of blossoms. Avoid adding any fertilizer and it should eventually reach equilibrium.

I would suggest that your problem lies in the plant being grown from seed. When you grow out seeds, many plants will turn out to be shy-blooming. Get a cutting propagated named clone that has been selected to flower and fruit freely.

Thanks! I will try to be patient. Gladys
