Visiting Oahu--Wahiawa Botanical Garden, Tropical at 1000'

Heliconia flowers

In the center of the island of Oahu is the Wahiawa Botanical Garden. Part of the Honolulu Botanical Gardens system, it is at about 1000' above sea level and contains tropical plants that like a lot of rain at cooler temperatures.  Conveniently located half way between Honolulu and the beaches of Oahu's North Shore, it features heliconias, figs, and economically important tropical plants such as coffee, chicle (source of chewing gum) and cinnamon, as well as spectacular ornamentals.

Plant Story--Daylilies, From Asia, Beautiful and Not Lilies

day lily Hemerocallis
Everyone always has grown daylilies and their story is well-known. It seemed. When I looked carefully, I totally rewrote this blog post.

Daylilies have been in U.S. gardens since the 1600s. It is commonly reported that both Dioscorides and Pliny in ancient Rome (1st century AD) wrote about them, but careful analysis has shown they were describing a lily, not a daylily. Daylilies came to the West from China, after 1500.

Visiting Hawaii--HIstoric Foster Botanical Garden

Path, Foster Botanical Garden, Honolulu
I recently took an off-season holiday in Honolulu, Hawaii. Inevitably, my steps took me to botanic gardens. One of Honolulu’s highlights is Foster Botanical Garden. In the heart of modern Honolulu, it was once part of the estate of the Hawaiian Queen Kalama (1817-1870), was planted with tropical trees that might become cash crops on the Islands by Dr. William Hildebrand (1821-1886) in the middle 1800s and ultimately donated to the City and County of Honolulu in 1930 by Mary Robinson Foster (1844-1930), of royal Hawaiian descent and widow of sea captain Thomas Foster (1835-1889). 

Many of the trees are huge, for example:
Queensland kauri, Aganthis robusta, an Australian tree in the Auricariaceae, a family of Southern Hemisphere conifers. They can grow 150 feet tall and 24 feet wide and produce lots of desirable wood.
