Always take the time to stop and see the beautiful flowers in each place you visit. Depending on the season, it can be the best show in town. For an example, when I was in Amsterdam in Spring, Keukenhof Gardens was in full bloom with Spring flowers. I don’t think I have seen that many flowers all in one place! It is really hard to beat Spring.
And then there is Cameron Highlands in Malaysia where it is “eternal spring” in the mountains. A site to behold. Of course don’t forget the English Cottage Gardens, in Great Britain. The English Garden with the natural look, filled with flowers and herbaceous borders will make you come back again and again to England. And here in the USA, we have some of our own gardens to visit such as the Biltmore Gardens in Asheville, North Carolina and Old West Bury Gardens in New York.
