Field Notes
It was a warm sunny day. It was very windy. My dad went to the beach not knowing what it was and brought it to our house. We planted it in our front yard not thinking it was going to survive for long but we were very surprised. Before our house was built it was a gravel pit so there is almost no nutritious dirt. Once we realized it was their to stay we surrounded it with a black net type thing. It kept it in one spot for a while but in the past couple year it has went outside of the net and has several pop ups where it has started to spread like crazy. I looked at the pictures on the internet and thought it was invasive so I decided to do my project on it. It was planted about eight-ten years ago.

You've done a good job of identifying this plant. Your photo of the leaf is very clear, and your photo of the thorns is great. But ... what really made me think that you've correctly identify this plant is your distance photo of the plant, which is very characteristic of rugose rose. Nice job!

Cool artsy sketch. Great story about moving a species and trying to manage its invasive growth habits. Your details about the poor, gravely soil quality are especially interesting - many invasive species are very efficient collectors and users of nutrients and can thrive in places where native species struggle.

You could do a really neat change-over-time experiment right in your front yard to see how quickly the plant spreads. Count the number of new shoots you see each spring, or measure the area of ground the plant takes up each year... Fun to watch and learn from.

Thanks for the complement. I will do the thing where i count the amount of new shoots I see each spring.

Cool idea. Add your shoot counts right on this observation so we can all learn from your research!

I'd be glad to post my information. :)
