What to KnowTrick-or-Treat in the GardenLos Angeles County Arboretum & Botanic GardenFriday, Oct. 174 to 8 p.m.$18 adult non-member; $15 children; garden members are free “according to membership level allowance” (but registration for all attendees is required)

The chances of a kid passing by a tree or two, or several shrubs, while wandering around a neighborhood on Halloween are pretty good, depending upon where your family likes to go trick-or-treating.

But what if you could enter a verdant world of pure tree-filled joy, a realm filled with grassy expanses, lovely blossoms, and the chirping of various birds and critters, all while enjoying a trick-or-treat scene?

It sounds like a scenario from a charming storybook, but it will come to live at the Los Angeles County Arboretum & Botanic Garden Oct. 17.

That’s when the leafy Arcadia landmark’s popular Trick-or-Treat in the Garden returns, all to give families the opportunity to savor an ethereal outdoor space while enjoying some of the hallmarks of the haunting holiday.

The afternoon-into-evening happening, which will conclude at 8 p.m., will feature “nature-based” treat stations.

And at every stop? Plant facts will be shared, giving kids a deeper insight into the flora of the historical and sylvan space.

Adding to the natural fun? Stations will feature a plethora of fascinating guest stars, including earthworms and carnivorous plants.

For sure, the tots can dress up in their costumes, maybe giving them an early run ahead of Halloween.

In fact, the Oct. 17 celebration is exactly two weeks before the eerie occasion, which makes it the perfect and pastoral moment to kick off the not-too-frightful fun in a peaceful garden setting.

Members at some levels can enjoy free entry, but everyone should register ahead of time.
