篇1

My Plant Friend the Sunflower

Do you have a best friend that is a plant? I do! Her name is

Sunny and she is a big, beautiful sunflower. Sunny lives on my

family's balcony in a pot of soil. We've been best friends for a

whole year now!

When I first planted Sunny's seed last spring, I wasn't sure if

anything would happen. But after just a few days, a tiny green

sprout poked up from the dirt. I watched her grow taller and

taller each week, reaching up towards the warm sun. Her stem

got thicker and her leaves unfurled, bright green and shaped like

hearts.

After a couple of months, a bigflower bud formed at the top

of the stem. It just looked like a green lump at first, but then it

started opening up. The petals emerged one by one, a vibrant

sunshiny yellow all around a big chocolate brown center. Sunny

was finally a sunflower!

Sunny makes me so happy every morning when I see her

bright, cheery face glowing on the balcony. I like to gently touch

her soft petals and tell her about my day. I think she enjoys

listening! Sunny reminds me to always look on the bright side

and be positive, just like how she naturally faces the sun.

I make sure to water Sunny regularly and my dad helps me

put plant food in her soil sometimes. I can't wait until next spring

when I get to plant her seeds again and watch new sunflower

friends bloom. Sunny has taught me so much about being

patient, optimistic and appreciating the beauty in nature. Plants

really can be great friends!
