I just got back from a week long trip in Glasgow! I visited my boyfriend who has been there during the summer for an internship. The weather was actually pretty nice. On one of the days that was a bit overcast we stopped by Glasgow Botanical Gardens which has several greenhouses including one called Kibble Palace which is a 19th century greenhouse.
There were so many cool plants. I am not really sure which part was my favourite! My boyfriend even enjoyed the gardens.
If it was this one that you liked, then yes they grow wild. This photo is actually from an area outside of Glasgow. But they also had one in the outside gardens of the botanical gardens. I saw them growing in front of homes as well. 🙂
