Public gardens provide a quiet oasis in the midst of many large cities in the world and they are typically on our list of tours whilst on holiday with my children – even now that they are in the 20s, (though they usually travel by themselves now :-(.
The Royal Botanic Garden in the heart of Sydney, Australia, Missouri Botanical Garden in St Louis, MO, Kumpula Botanical Gardens, Helsinki, Finland and so many others provide a relaxing retreat from the noise of car and public transport.
Powell Gardens, though calling itself the botanical gardens of Kansas City, is actually located some 43 minute drive from Kansas City in the town of Kingsville, MO. (actually closer to Lone Jack, Missouri)
Currently, Powell Gardens is a nonprofit 501 (c) 3 organisation operating on gifts and donations. It is a beautiful place with seven themed gardens, the Marjorie Powell Allen chapel (available for weddings, funerals), educational center, picnicking areas, and year round organized educational and art events, activities, programs, featured events, and annual festivals. If you have time and can schedule a tour, it will be worth the time. If your legs cry for a rest, hop on the free tram which runs daily to the various gardens and is wheelchair accessible.
Please bear in mind, the gardens are closed for daily admission in January and February. As far as i can tell, the only way to get to the gardens is via car (no public transport), so your visit will need to be well planned.
Powell Gardens maintains a Facebook page as well as other social media outreach.
