While we were visiting the Big Island of Hawaii, Dave and I took a trip to Hawaii Tropical Botanical Garden. Located north of Hilo in a real tropical rainforest, the garden is a lush paradise of exotic plants from rainforests around the world, including lots of orchids.

We spent half the day soaking in the stunning floral beauty. Innumerable tropical flowers, a koi pond, waterfalls, jungle birds, and ocean vistas kept our cameras clicking away. The garden is a non-profit sanctuary for many rare plants, helping to preserve them against the threats of habitat destruction and climate change. Hawaii Tropical Botanical Garden also provides educational programs, and spreads Hawaiian beauty by shipping tropical flower bouquets within the USA.

And to prove that we actually did take pictures besides orchids, below are a baby pineapple, a pink ginger flower, and a yellow heliconia flower. In the last photo, Onomea Falls rushes through the garden valley. What a paradise!

February may be the shortest month, but it’s jammed-packed with orchid shows to enjoy. Don’t miss these opportunities to see amazing flowers, meet other orchid enthusiasts, and learn lots about growing fascinating plants.

The Big Island of Hawaii has perfect growing conditions for many tropical orchids. One type frequently found there is Spathoglottis plicata, or the Philippine ground orchid. Unlike most commonly cultivated varieties, it’s a terrestrial, meaning that it grows in soil.

This orchid is native to a large area of south Asia, stretching from India through Thailand, Malaysia, Singapore, Indonesia, northern Australia, the Philippines, Taiwan, the Japanese Ryukyus, Fiji, Samoa, and other south Pacific islands. Although not native to Hawaii, it has naturalized there, and enjoys growing where it receives full sun, regular water, regular fertilizer, and warm temperatures.  It has also naturalized in other tropical areas of the world, including the Caribbean and southern Florida.

One reason the Spathoglottis has spread around the world is due to its ability to self-pollinate. This species is one of a handful of orchids that don’t need a pollinator to carry pollen from one plant to another. Instead they can fertilize themselves with their own pollen. Many plants we saw on the Big Island were full of seedpods like those shown below, demonstrating the success of this adaptation.

I can’t think of any better way to escape the winter doldrums than to head to a warm and beautiful tropical paradise. Dave and I just returned home from such a place, the Big Island of Hawaii. We stayed at Art & Orchids Bed and Breakfast in Kea’au, south of Hilo. True to their word, the B&B has hundreds of orchids all over their beautiful gardens. Hosts Markie and Jerry provided a very comfortable garden room, delicious breakfasts with exotic tropical fruits, and lots of helpful info about enjoying the local sites. There were dozens of orchid plants blooming on their grounds while we were there, but Markie told me that most everything comes into bloom in spring, so that’s the absolute peak for orchid lovers. We took zillions of pictures around the island, and I’ll have plenty more in future posts. For now, I’ll start with a few orchid pictures from the B&B’s own gardens.

It was an extra special time to be in Hawaii, as we joined the state in celebrating the  inauguration of its native-son, President Obama. As ardent environmentalists, we are hopeful that our new President’s policies will help to heal the damage we have inflicted, and help to preserve orchids and other joys of the earth. And if you’d like to escape a cold, gray winter, we can highly recommend a stay at Art & Orchids.

While the rest of the country has been frozen, California is having a winter heatwave. Yesterday San Francisco set a new record high for the date at 74F (23C,) and there may be another record high today. Since I’m fortunate to live someplace with a mild climate, and I’m able to grow orchids outdoors all year, I won’t complain about my wintertime garden work. But I wasn’t expecting watering to become a new winter chore. Even though most orchids are dormant, they’ve needed a little drink to keep from totally drying out.

Other more typical winter chores include weeding and picking up fallen leaves and flowers. It’s best to be proactive about weeds. If they flower and set seed, your weeding tasks will multiply, so get them beforehand. Leaf and flower debris can provide hiding places for unwelcome pests, so these should be cleaned up too. They make great additions to homemade compost.

And speaking of pests, watch for aphids, scale, mealybug, and spider mites. Many natural controls work well and are safe for the environment. I go after pests by mixing a couple spoons of rubbing alcohol, a spoon of mild dish soap, and tepid water in a spray bottle. I spray the mixture on the plants, making sure to get the undersides of the leaves, too. This mixture is effective against most plant pests. Neem oil is another natural product that can be sprayed onto plants to kill most overwintering insects. You can find neem at most garden centers and plant stores.

To top off these winter chores, we’re pulling together some great new blog material in the next couple weeks, so check back again soon!

Dave and I decided to welcome the new year with a visit to Strybing Arboretum in Golden Gate Park. The Botanical Garden at Strybing Arboretum has thousands of varieties of plants from all over the world. We didn’t see any orchids, but we enjoyed some of the other sites of the park.

First, there’s a beautiful Princess Flower against a background of ferns. In the middle, this great Heather shrub is a South African native. On the right, a large bromeliad sports a bright red bloom.

I don’t know what this flower is on the left, but I loved the shape and structure. The aloe in the middle is another fascinating South African native, with a hypnotic spiral growth pattern. On the right, a bed of ferns adorns the base of the new de Young Museum.

A young boy walking near us at a pond thought this was an evil red-eyed duck. I’m not very good at identifying birds, but I think it’s a coot. It could still be evil, though. On the right, 2 park residents warm up in the winter sun.

Looking more like a hyacinth than an orchid, Arpophyllum giganteum has dense clusters of pretty purple blooms. This orchid can tolerate a wide range of temperatures, but needs cool nights in  winter in order to bloom. Here in San Francisco, I grow it outdoors all year with bright light and regular water. Its native habitat stretches from Mexico to Venezuela.

Close-up photos show that the mini flowers do resemble other orchids, just upside down. The lip of the flower is on top, and a hint of yellow color shows the location of the pollen. Dozens of 3/8 inch (1 cm) flowers spiral around a spike that can reach 16 inches (40 cm) in length. Dave photographed a particularly nice specimen a few years ago at the San Francisco Orchid Show, shown in the final picture.

If it’s feeling cold and dark where you live, there’s no better escape than a very tropical orchid show. Welcome in the new year with beautiful flowers that take your imagination away to warmer, sunnier lands.  This is a partial listing of shows, so if you don’t see one near you, check your local orchid society or botanical garden.

This mini Masdevallia relative, with a flower smaller than a pea, has a long name, Scaphosepalum. Despite its diminutive size, it’s capable of staying in bloom for months or even years at a time. The new flowers emerge in succession along a lengthening spike, while the older flowers fall off.

Several years ago, this orchid bloomed continuously for over 2-1/2 years, and had a flower spike that reached over 3 feet (0.9 m) before it finally stopped flowering. This year it’s been in bloom a mere 8 months. I’m hoping to keep it happy enough to challenge my previous record. For this plant, that means regular water and high humidity, similar to its native home atop the Andes in South America.

An insect managed to pollinate one of the flowers. This seedpod matured quickly in a few weeks (compared to many other orchids whose seedpods take months to mature.) The photo on the right shows the tiny burst seedpod resting on a bed of moss. The seeds look like tiny white fibers, and are easily picked up by the wind and scattered like dust. Maybe next year we’ll have some Scaphosepalum weeds growing in our garden.

I’ve been loving this orchid book I got, a great gift from Dave’s grandmother Audrey. It’s The New Encyclopedia of Orchids: 1500 Species in Cultivation, by noted botanist Isobyl La Croix of the Royal Horticultural Society. Within its 500 pages, there are lots of interesting and unusual orchid species, many not commonly seen. You’ll find Masdevallia relatives Dracula and Platystele, Oncidium relatives Capanemia and Rodriguezia, and bizarre Australian orchids like Chiloglottis and Corybas.

This book supplements beautiful photography with detailed care information, from Acampe to Zootrophion, and also reflects recent scientific research and name updates. There are hundreds of  gorgeous pictures, and more stunning flowers than you could ever imagine.

To all, “Happy Hanu-kwanzaa-mas,” as I like to say. Dave prefers “Merry Knish-mas” from his favorite cartoon Chowder. To Audrey, thanks so much for the wonderful book. We both love you very much.
