Discovering hidden flowers in my jungle garden

In the tropics everything grows so well, that sometimes I have to think about a certain plants aggressive nature.  I like to be able to see that all the plants are surviving ok, but still have a full tropical look to the garden. I am often torn about removing certain plants that have become too aggressive for my small garden.

A plant at the back has huge leaves, rounded, and very firm, and I love the way they scratch against each other in the wind.  I planted two of them - one against the fence and the other at the back, next to the sexy pink lady. Hubby loves the feeling that we live in the middle of a lush tropical rainforest.  I worry that the plants are crowding each other out. Is there too much now in that corner?

The difficulty is that some of those plants will go dormant in the dry season.   I see more turmeric has come up, so have to be careful I do not create bare patches..  I have that in the veggie perennial bed now, so will remove it from the corner, leaving more room for flowers.  My large heleconia is starting to flower, but I wonder at my logic of planting this - I think it is too big for this area.

 This flower doesn't look big, but as it unfolds will be about 3ft high!  It is upright, as opposed to the sexy pink lady which is hanging down. Each stalk will only flower in its second year. - do I have enough room for this to hang around two years before getting a flower?   I moved some of this to the central island, but it is not doing well.  I can see why - those plants compete with palm roots, have to rely on whenever it rains to get watered, and occasionally get a little compost flung at them.  Not like these pampered babies!

  This little anthirium was started from a piece of my neighbours plant, and I love the deep red colour. I hope it doesn't get lost in amongst the bigger, more robust pink anthirium.

 The beehive ginger has not enjoyed the neglect I have shown it, but then again it might already be going dormant for the dry season.  This area really needs a clean out, and I have a friend who needs some plants for  a garden she is creating. Then again the beehive goes pretty mcuh dormant in the dry season too.

 I like the way the ground orchids are framing the side path, and am thinking of  replacing all the roheo along the front edge with ground orchids - so much prettier and well-behaved.

 I have this salad bowl that I never used and thought it would make a good extra birdbath, and to stabilize it a put in a  few rocks, and this little ceramic bird.  I think I may have overdone it though, as the birds have not come near.

 The butterflies might like it though - they like to sun themselves on rocks alongside the water, so I have heard.

This small heleconia in front of the birdbath is probably much more suited to my garden.   Notice how the grasshoppers have chewed along the edges of these leaves....

How come other gardeners seem to manage to plant plants that stay the size they are supposed to and don't run rampant through the garden, obliterating other plants as they go.
Oh yes!  They don't live in the tropics.
