such interesting seeds.. to me anyway, not familiar with tropicals.

Nothing like that in Central FL, really neat looking.

We have a huge one on the pool deck in Miami Fl. There's quite a few of them here in landscaping. They flower and fruit too.
and drop seeds and they sprout on top of the soil. I picked up one and planted it.
It is still a very small plant .
I used to have a big one as a houseplant: total mite magnet and very spiny.

I have grown P. utilis in ground here in Central Florida for about 15 years. It started flowering a few years back. I was looking forward to seeing the fruits on my plant. I quickly learned at flowering time that pandanus are dioecious and my plant was male.
