That word for the idiom is perfect for spring-to-summer time like this, right? But, please beware of the idiom itself:
lead someone up the garden path
See? A Nice idiom doesn’t mean having a nice meaning. I don’t know why it used “garden path”. Is it because some garden has a labyrinth that can make you wasting your time there? Nevermind. Just never ever let someone (or something) leads you up the garden path!
ps: people also say “lead someone down the garden path”, both have the same meaning.
