My haiku poems

Can you guess what my poems is about

Haiku number 1

I am very long


You can wear me how you want

I go on your neck

What am I?

Haiku number 2

I grow in gardens


I am healthy and orange

You can eat me up

What am I?

Haiku number 3

I come up at night


I shine brightly in the sky

I am bright silver

what am I?
