Visiting Hawaii--Cactus Garden in Honolulu


Kapi'olani Community College cactus garden and the farmer's market

A farmer's market gathers each Saturday in Honolulu, just below Kapi'olani Community College. It was fun shopping there: macadamia nuts, kona coffee, guavas, pineapples and chocolates. But I was distracted and spent most of my time in the garden behind the farmer's market, Kapi'olani Community College's Cactus Garden.

Plant Story--Evening Primroses, Beautiful Whereever You Meet Them

evening primrose
There are 145 species of evening primrose, Oenothera, 80 of them native to the United States.While there are more different species in western North America, the common evening primrose, Oenothera biennis, can be found in all but the Rocky Mountain states.

Evening primroses have big flowers. If you find them open after 7 am or before 7 pm, the flowers are likely yellow. Night-flowering species are often white and close in daylight, so if you are to see them open you need to go out in twilight, wander with a flashlight or get up early. On a cloudy morning they stay open longer, but the white species tend to grow in drier places, where cloudy mornings are less common.

Visiting Australia--Remote, Central, Alice Springs

Hills around Alice Springs

I knew almost nothing about Australia when I read and loved Nevil Shute's A Town Like Alice. So, like generations of tourists, when I visited Australia, I was eager to see Alice. Alice is of course, Alice Springs, a small city in the center of Australia. Australia, the world's smallest continent or largest island, is generally warm and dry. Alice, in the center, is in the middle of the sort of desert where they tell you in October, "before this week, our last good rain was in January."

Plant Story--Evening Primroses, Names and Relations

Evening primroses were one of the first midwestern wildflowers I learned. Partly because they are so spectacular
Missouri evening primrose Oenothera missouriensis

I quickly figured out they were not roses or primroses (more on that below). The evening primroses are some 145 species native to the Americas, in the genus Oenothera, in the evening primrose family, Onagraceae. The U.S.D.A. lists 80 species of Oenothera native to North America. With beautiful flowers!

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.
