One of the underrated and overlooked places to see while visiting the city. The place has an amazing collection of plants in a relatively small area. Parking is paid, but entry to the park is free.
There are several different sections for flowers, vegetables and herbs to explore.
Directions via Google map may not be clear so it may help to get directions for the Envirotron Pavilion which shares the parking lot with the Botanical garden.
