Visitors to Franklin Park Conservatory and Botanical Gardens stop at the front desk then head up the stairs to the right. Then, they are presented with options: the north or south greenhouse, the gallery, the gift shop or the caf茅.
It takes a bit more exploring to find the Dorothy M. Davis Palm House. From the outside, the elegant building looks like a glass castle. Inside, it鈥檚 filled with big, leafy, green plants and a fountain.
But Franklin Park Conservatory President and CEO Bruce Harkey says sometimes, visitors miss it entirely.
鈥淭hey never see this really amazing, iconic building, which is one of the oldest significant architectural masterpieces in the city,鈥 Harkey said.
Under the conservatory鈥檚 new North Star Master Plan, the Palm House would be one of the first places visitors see. The plan lays out how the conservatory hopes to grow in the next 25 years.
One major change listed in the plan is building a new entrance on the west end of the gardens. That way, visitors could enter from Franklin Park. Coming out of the center, they鈥檇 find themselves in what is now the grand mall way, looking at the historic palm house.

Planting the seeds
The Palm House was built in 1895. At that time, wealthy Victorians often had greenhouses in their backyards. Inspired by the City Beautiful movement, an urban reform of the late 1800s, Columbus built the public glasshouse.
鈥淎nd it became a place for people who live in Columbus to kind of go on a trip around the world by coming to the conservatory,鈥 Harkey said.
Today, Franklin Park Conservatory and Botanical Gardens sees around 400,000 visitors a year. They can still travel the world, as they walk from the cool, rocky Himalayan Mountains, through the dense rainforest, and into the arid desert.
Those geographic biomes are expected to change under the North Star plan, but visitors will still see plenty of the world. Harkey said the walls between greenhouses will be removed, creating a larger biome focused on plants from dry environments all over the planet.

Harkey said the palm house, after renovations, would also have rare and endangered palms from all corners of the globe.
鈥淥ur vision is a world that celebrates nature as essential to the human experience,鈥 Harkey said.
The conservatory last broke down walls between biomes to create the large Pacific Island Water Garden on the south side of the building.
The North Star Plan also calls for the creation of two new greenhouse areas. One would house a permanent butterfly exhibit. The other would be combination gallery, garden and 鈥渉ot shop鈥 for glass blowing. It would showcase the conservatory鈥檚 collection of Chihuly sculptures.
Dave Chihuly is an American artist known for large, colorful glass artworks that spiral and flair. Franklin Park Conservatory owns more of his work than any other botanical garden. Harkey said the conservatory鈥檚 collection is also one of the top five Chihuly collections in the world.
Growth
The Chihuly collection hasn鈥檛 always been here, of course. Neither has the children鈥檚 garden nor the community garden.
Until the 1990s, the conservatory was just the Palm House and the Show House. It underwent a $14 million expansion for Ameriflora 鈥92, a six-month-long international horticultural exhibition. When the event was over, the modern Franklin Park Conservatory bloomed with more additions over the years.
One of those is a water area where kids 鈥 and adults 鈥 can take off their shoes and splash and play in the waterfall and faux rocky pools.
鈥淢y daughter absolutely loves the water area here. And now that the butterflies are out, she loves coming to see the butterflies,鈥 said Leah Korman.
Korman has been a member of the conservatory for three years, but she also remembers spending time there as a child.
鈥淭his whole area is new,鈥 Korman said, speaking of the Children鈥檚 Garden. 鈥淲hen I grew up, it was just the indoor, exhibits that we came to.鈥

Feeling nature
On a field trip with Dublin鈥檚 Chapman Elementary, 9-year-olds Estelle Pina and Claire Tiefenthaeler said the Nature Play Zone and Canopy Walk in the Children鈥檚 Garden are their favorite parts of the conservatory.
鈥淎nd we鈥檙e just, you know, looking around, feeling nature!鈥 Pina said.
鈥淲e can, like, be kids, run around, and play with things that you normally don鈥檛 get to play with and experience,鈥 Tiefenthaeler said.
Bianca Aiub and Amreen Karim 鈥 9 and 8-years-old respectively 鈥 seconded Tiefenthaeler鈥檚 thoughts. They said they can鈥檛 play with sticks at school.
Aiub and Karim think the conservatory is already pretty perfect, but they might have a few additions to suggest. Aiub wouldn鈥檛 mind a movie theater that showed movies about nature, and Karim wants to see a bird area.
Those things are not in the current plans, but the North Star Master Plan does include more gardens, including formal European gardens and underground parking.
Big changes may still be far off, though. Harkey guesses that the restoration of the Palm House and the attached Dorothy M. Davis Showhouse may begin in 2026 and would take about a year and a half to complete.
Other aspects of the North Star Master Plan would follow.
