Tegarayama Conservatory Botanical Garden

Located 1.8 km southwest of Himeji Station, the botanical garden has two large and small dome-shaped conservatories as the main buildings. An admirable N. trunkata is on permanent display in the large conservatory. In the backyard, historical hybrids of Nepenthes (Koto series: N. wrigleyana, N. coccinea, N. henriana, etc.) have been cultivated for many years. Also, egret flower (Habenaria radiata), the city flower of Himeji, can be observed in the dedicated greenhouse through the year.

Hyogo Prefectural Flower Center

This garden has the largest collections of carnivorous plants in Japan. There is a greenhouse dedicated to carnivorous plant, in which many kinds of Nepenthes, Drosera, Pinguicula, Roridura, etc. are displayed under superb conditions all year round in the 2 green houses. You can see the giant N. clipeata and N. pervillei, introduced in the 2018 ICPS Conference. The Sarracenia collection in the courtyard is amazing. The Nepenthes collection was certified as the National Collection in 2020. Furthermore, the 55.5-cm tall pitcher of N. truncata was certified as the Guiness World Record in August, 2022. The area originally used to be a swampland and habitats of carnivorous plants. D. lunata and D. tokaiensis growing wildly can be found in a few spots.

5. Field trip to the local habitats

May 30 (Tue)

We will visit the habitats in Hyogo Prefecture (Abiki Marsh and Nishiwaki City) by rental cars from Himeji. D. lunata, D. tokaiensis and D. rotundifolia will be seen there.

Please note that the destination of the field trip may change depending on the condition of the habitats.

Participants of field trip to the habitat of Pinguicula ramosa will travel to Shinagawa by “Hikari” Shinkansen train, then move to Kitasenju by train and stay at hotels in Kitasenju. (Train fare and accommodation fee are your own expense. Japan Rail Pass can be used.)

6. Field trip to the habitat of Pinguicula ramosa

May 31 (Wed)

We will move to Tobu Nikko Station from Kitasenju by Tobu Line train. Large luggage can be checked in coin lockers at Tobu Nikko Station. We will take taxies from the station to the entrance of the climbing trail, then we walk a gentle ascent for 2 hours to the habitat of Pinguicula ramosa.

Please note that it might be too early to see the full bloom in this season.

Nikko is a world-class tourist destination. The Nikko Toshogu is a part of the World Heritage Site, “Shrines and Temples of Nikko”. It might be worth it to stay in Nikko that night for sightseeing on the next day.
