This summer, the Osaka Prefectural Flower Cultural Garden (大阪府立花の文化園) in Kawachinagano, Osaka, is expanding its "Wind Chime Wall" — the lattice display of wind chimes at the event plaza that proved popular last year — and planting sunflowers at varying heights in the flower-picking garden on the roof of the event hall. Both spots make for great summer photos, giving visitors a chance to capture a memorable shot of the season. (Sunflowers are expected to be at their best from late July to mid-August.)
The event hall is also hosting the garden's popular annual "World Insect Exhibition," which this year includes tortoises among the animals visitors can get close to.
Other highlights include sprinkler water play at the lawn plaza, an "Exciting Quiz Hunt," the rain-friendly "Begonia Exhibition" in the greenhouse, ayu (sweetfish) catching, an insect specimen class and creature observation session led by Professor Hirai of Osaka Metropolitan University's graduate school, and a "Summer Kids Workshop" series in the first-floor training room of the Center Building — about 20 booths in total, well suited to summer homework and independent study projects, with some booths available on weekdays this year. The event plaza's HANARE space debuts a new "Carnivorous Plant Laboratory," and the garden is also holding its first-ever plant-based fabric pounding (tataki-zome) workshop.
The on-site restaurant and cafe are rolling out summer menus, and the shop is holding sales as well.
World Insect Exhibition
This hands-on exhibition at the event hall lets visitors get up close with insects and reptiles for a chance to learn, discover, and be inspired. This year, tortoises are among the animals visitors can touch. A stamp rally is also running in partnership with the "World Insects and Reptiles Museum" at Harvest no Oka in Sakai, rewarding visits to both venues.
Date: July 18 (Sat) to August 30 (Sun), 9:30 AM to 5:00 PM (last entry 4:30 PM)
Carnivorous Plant Laboratory
The HANARE space at the event plaza transforms this summer, letting visitors take a close look at popular carnivorous plants such as Nepenthes (pitcher plants), Venus flytraps, and Sarracenia, as if browsing a living field guide.
Date: July 18 (Sat) to August 30 (Sun) (free admission)
Location: Event Plaza
Begonia Exhibition
About 120 varieties and 300 pots of begonias, centered on shrub begonias and including wild species, are on display — a chance to see the large begonias only a botanical garden can offer.
