Garden Improvements – The Welcome Pond

Water Lilies thriving in the Welcome Pond

Water Lilies thriving in the Welcome Pond

The Garden is always growing and improving! Behind the Garden Entrance Gate was an area densely packed with various trees and impressive rock formations surrounding a natural blue-rock pond. In order to better highlight the pond and rock formations, several trees were removed to expand the viewing area. Garden staff excavated the pond and populated it with an array of eye-catching water lilies. All around the pond a beautiful groundcover Hemigraphis colorata was planted and several Medinilla magnifica are now perched upon the rocks, showing their bright pink flowers. Visitors now have a new feature to enjoy as they first enter the Garden. We call it the “Welcome Pond”.

The Garden has also added many Vireyas or Tropical Rhododendrons to its collection. Vireyas have exotic, wonderfully scented, vibrant flowers. Most of the 300 species grow in tropical but mountainous regions in New Guinea, Borneo, Sulawesi, Sumatra and the Philippines.

Many grow epiphytically (without soil) in tall trees in cloud forests and are cold hardy to about 40 degrees Fahrenheit. We have planted our Vireyas on the lava cliff side of the Boardwalk.

The common name "Cannonball Tree" comes from its large, spherical fruits.

The Garden’s Magnificent Heliconia Collection

Heliconia

Heliconia Latispaha X Heliconia imbricata cv. “Jose Abalo”

When the world’s foremost expert on Heliconias, the late Mr. Fred Berry, visited Hawaii Tropical Botanical Garden he marveled at the size of our Heliconia mariae and wondered aloud how Garden Founder Dan Lutkenhouse could possibly have gotten them to grow so large. Mr. Berry had traveled the world collecting and naming Heliconias and had never seen such grand specimens. He was co-author of the first book on the genus, Heliconia an Identification Guide, which includes many photos taken of specimens in the Garden.

Mr. Berry’s remarks are a testament to the magic of Onomea. Few places on earth can rival the growing conditions found here. The valley’s constant warmth, high humidity, 160“ of annual rainfall and rich volcanic soil lend an exuberance and vigor to these plants they seldom achieve, even in their native habitats.

From the inception of the Garden, Dan Lutkenhouse began collecting and displaying Heliconias. Today the Garden’s collection includes over 200 varieties of rare and wild collected specimens, and has gained International notoriety among botanists and taxonomists as one of the finest and most extensive collections of Heliconias on public display anywhere.

Heliconias are conspicuous for their inflorescences made up of bracts, modified leaves which come in a vast array of bold colors, shapes, and sizes, and can contain as many as 50 of the tiny true flowers inside. Each Heliconia shoot will produce one inflorescence with multiple bracts that are arranged in one even plane (distichous) or spirally arranged due to the twisting of the rachis. Inflorescences are either erect or pendant. After flowering a shoot will wither and die.

Heliconias are mostly native to Tropical America along with a handful of species from the Pacific Islands. An easy way to recognize a Pacific Species is by the lack of color on their bracts. They are a dull green in color resulting from the fact that its pollinators are night feeding bats that use certain chemical cues and odors rather than sight to locate food sources. Their more numerous American cousins are pollinated by hummingbirds drawn in by the colorful bracts. In Hawaii, earwigs replace the hummingbirds and bats as pollinators.

Heliconias have banana-like leaves and were formerly classified with the banana family but are now classified as their own family, Heliconiaceae. The family name Heliconiaceae and its single genus Heliconia are a reference to Mt. Helicon in Greece, home of the Muses, because of their similarity to the banana family, Musaceae, which refers to the Muses.

Heliconia longissima

During the Summer months, our Heliconia collection is in full bloom. Some highlights include the rare Heliconia longissima. Standing at the Head of the Heliconia Trail, visitors are dwarfed by its inflorescences dangling over 10’ long containing as many as 50 bracts and foliage towering 20’ feet above.

Located by the Founders’ Birdhouse, the aptly named Heliconia regalis cultivar “Barnum and Bailey” produces hairy, bright orange and yellow bracts that could really be “The Greatest Show on Earth” to the Heliconia enthusiast. If only these bracts kept and traveled well, they would surely have taken the cut-flower industry by storm.

Another rare specimen is Heliconia reptans which displays its inflorescence on the ground like a snake, can be seen across from Fern Circle.

Anthurium Corner

A beautiful new addition to the Garden is Anthurium Corner. This area was made possible in part by our newest Benefactor, Marian Kobayashi who, as a tribute to her late parents, (Anthurium farmers for many years on the Big Island) donated $10,000.

Anthurium Corner

Anthurium Corner features every shade of Anthurium andraeanum nestled under a large Mulesfoot Fern (Angiopteris evecta).

This magical corner features every shade of Anthurium andraeanum (Araceae family) nestled beneath a large prehistoric-looking Mulesfoot Fern (Angiopteris evecta). The giant fern provides shade that these Anthuriums need to thrive. A bench across the path from this colorful bounty provides a quiet place to sit and admire the beauty.

Anthurium cupulispathum.

Anthurium cupulispathum

In addition to Anthurium Corner, the Garden has a large collection of species Anthuriums on display. One eye-catching species is Anthurium cupulispathum. Native to Ecuador, this Aroid has become a favorite of garden visitors. Its huge inflorescence is a sight to behold; the petal-like spathe forms a cover or “cupola” over the enormous hanging flower-bearing spadix. The spadix can reach up to three feet long and can host thousands of tiny flowers.
