While doing my 'Spring Cleaning' in the backyard today, I found these three seeds...or maybe berries under some leaves.
They are a grey/aqua color...about half inch long...and bright orange inside.
At first I thought they must be artificial...the woman that used to live here had alot of fake plants around...even outside, but when I cut off the tip of one, I realized they were real.
There may be some sort of seed inside, but until I find out what they are, I'd rather not compromise them.

Any ideas on what they might be?

The only thing nearby would be Palms.

Thanks!
