Can you feel it? Somewhere through all this heat and dust, there's the tiniest of fragrant chills in the air — it's spice and pumpkin time! (Or maybe that's just the overwhelming aroma of cinnamon brooms at local grocery stores.)

Anyway, I don't know about you but I'm more than ready for some holiday normalcy. And there are plenty of events coming up to celebrate. Just remember to have a mask handy, and note that many activities ask people to maintain some social distancing.

And for plant and nature lovers, there are great opportunities to get your hands dirty, such as removing invasive species in Lunada Canyon in Rancho Palos Verdes or potting your own herbs at the Greystone Mansion Demonstration Garden.

Here are more classes, flower shows and garden-y Halloween events to keep you busy into October. Email garden and plant-related events to jeanette.marantos@latimes.com at least three weeks before the event and we might include them in the calendar.

Through Sept. 26

"World of Bromeliads" exhibit at the San Diego Botanic Garden, 300 Quail Gardens Drive in Encinitas, features interactive displays throughout the 37-acre garden of these tropical, exotic plants, which range from Spanish moss and air plants to pineapples and houseplants with extraordinary blooms. The exhibit includes a station where visitors can use microscopes to see the biodiversity of organisms living in a bromeliad's "water tanks," the natural reservoirs where some of the plants store water. The garden is open 9 a.m. to 5 p.m. Wednesdays through Sundays (closed Mondays and Tuesdays). Admission is $18 ($12 seniors, active military and students with ID; $10 ages 3-17; children under 3 and members free.) sbdgarden.org

Roger's Gardens "Cabinet of Curiosities" Halloween Boutique, 2301 San Joaquin Hills Road in Corona del Mar, pays homage to Hollywood's classic horror movies, with lifesize depictions of Dracula, Frankenstein, the Bride of Frankenstein, the Creature From the Black Lagoon and the Mummy. Each "creature" has its own room of merchandise, from a thick archway of grinning skeletons to beakers of slimy green liquid and very menacing insects safely encased (one hopes) in resin. It's more creepy than scary, and everything is for sale. Open 9 a.m. to 6 p.m. daily. Masks are required for unvaccinated visitors (based on the honor system) and the number of people inside the store will be limited, so be prepared to wait in line.
