Tokyo's largest botanical garden, Jindai is planted with 120,000 trees and bushes representing 4,500 different species. The 750 cherry trees in the cherry grove turn this into a major destination during hanami season, and the plum and rose gardens are also very popular.
The map you receive when you enter the gardens includes a detailed chart showing which flowers are in bloom during any given month.
One essential stop all year round is the park's greenhouse, which has six different climate zones. The Tropical Room houses numerous tropical fruit trees and a collection of carnivorous plants, and always has something in bloom. Other greenhouse rooms are devoted to orchids, begonias, water lilies and cacti.
The greenhouse's air-conditioned exhibition room is furnished with tables and chairs and drinks vending machines, making it a good spot to take a break from flower-viewing, especially on hot summer days. Other break spots include an indoor cafe at the opposite end of the park, serving drinks and simple meals like curry rice, and an outdoor kiosk near the rose garden that sells hot dogs, fried chicken and ice cream.
In addition to the sprawling main garden there's a separate aquatic plant garden located on the opposite side of Jindai Temple, with free admission. While the park isn't near any train station, there's frequent bus service from Chofu Station on the Keio line and Kichijoji and Mitaka Stations on the JR line, with bus stops right in front of the main entrance.
