Yellow Hibiscus IV

anthers and stamens

Evening breezes brought to a halt my series of hibiscus bloom photographs, that bloom faded and shriveled, to be replaced by another. I captured the images of this post on a very quiet summer evening. This bloom was facing up closer to vertical that the previous.

A key identification for all 300 species of hibiscus is the long stamen tube. I have yet to see a local insect interacting with the stamen, always they are in the flower throat. In the tropics, pollination is thought to proceed from large butterflies and birds.

Here are three macro photographs of this bloom, all from the Canon 100 “macro” lens. I learned by experience to tamp down the diaphragm to the smallest setting, f / 32 for this lens. The different aspects were achieved by moving the lens objective closer to the bloom. This is a “fixed” lens, it has one focal length.

Yellow Hibiscus III

anthers and stamens

Nyctinasty (flower response to light: opening with or closing without light) in hibiscus plants is a mechanism to protect against adverse conditions such as cool temperatures that can be damaging. Through a lack of light stimulus and circadian rhythms the plant is able to trigger the molecular movement of ions to allow for the closing of the flower.

Here are three macro photographs of this bloom, all from the Canon 100 “macro” lens. I start with the shutter diaphragm open at 4.0 (“F-stop”), a little narrower at 4.5 and a bit more at 9.0. For this lens the maximum opening is at 2.8, the narrowest is 32. As the opening narrows (F-stop increases) the exposure time needed to capture enough light lengthens and the range of the image in focus increases.

Yellow Hibiscus II

flower and buds

This is a perennial, commonly known simply as “hibiscus”, or less widely known as rose mallow. Other names include hardy hibiscus, rose of sharon, and tropical hibiscus.

The hibiscus flower is traditionally worn by Tahitian and Hawaiian girls. If the flower is worn behind the left ear, the woman is married or has a boyfriend. If the flower is worn on the right, she is single or openly available for a relationship.

Yellow Hibiscus I

flower, buds, bee

Yellow hibiscus, the state flower of Hawaii was recorded in ancient Greece. In the photograph is captured several unopened buds, behind the flower, and a bee in the flower throat, attracted by nectar there. It is a small bee, of the Halictidae family, that lives alone in a ground nest and also called a “sweat bee,” from being attracted to perspiration.

Spider Orchid Grand Flowering

grand flowering of an anniversary present to my wife

Here in Ithaca we have a greenhouse specializing in orchids. Several years ago if visited and picked up several for my wife, Pam, as a present for our wedding anniversary. Pam’s orchids site in our east facing bay window. This Caladenia, or spider orchid, has bloomed several times under her care. This bloom was especially successful.

These flowers are an achievement. Caladenia are difficult to maintain and cultivate outside of their native environment. Most are endemic to Australia and New Zealand.

Woody Peony 100 mm

Macro series

See my May Woody Peony postings for background on this peony variety.

These photographs were taken with a Canon EOS 5D Mark IV dslr and the Canon EF 100mm f/2.8 Macro USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head.

The morning breezes of May caused me to “up” ISO to 1600 for a faster shutter speed at higher f-stop.

Taking full advantage of the macro lens, the higher ISO helped to maintain sharper focus on the highlighted feature, in this case the stamens.

A gallery of macros with various settings and aspects of the bloom.

Woody Peony Reader Query

“It is difficult / to get the news from poems / yet men die miserably every day / for lack / of what is found there.” Asphodel that Greeny Flower WC Williams

Here is a Sunny Sunday reader assignment. Which handling of this woody peony blossom do you prefer? Please leave your preferences in the comments section with details of your reasoning. Thank you!!

These photographs were taken with a Canon EOS 5D Mark IV dslr, new for me as of 2020, and the Canon EF 50 mm f/1.2L USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head. This setup allowed me to fiddle with camera settings, here you see a variation in the width of the shutter diaphragm opening, or F-stop. The smaller the opening (higher F-stop) less light is let through to the image sensor, longer exposure time (allowing the subject to move, as in the morning breeze) offset by greater depth of field, more of which provides sharp focus as the subject elements are further from the lens.

In this first photograph, the F-stop is moderately high. The entire blossom and plant are in focus, the background moderately blurred though still recognizable.

For the second photograph F-stop is low, opening up the shutter diaphragm, allowing more light in for a faster shutter release, less time for the morning breeze to rise up and ruin the shot. The beautiful background blurring, bokeh, is a feature of this 50 mm lens. At the same time, at F/4.0 the shutter diaphragm is not wide open. The blossom is entirely in focus, many plant leaves and the other blossom, to left, are out of focus. This places emphasis on the primary subject of the photograph while providing a feel for the surroundings.

Here are the same photographs, click on one to open a gallery for you to flip back and forth to compare.

Woody Peony, Yellow Still Life 50 mm

Yellow for this last day of May 2021

This yellow woody (also called tree) peony blooms later than our red varieties. The first set of three were photographed May 26, 2021 have unopened buds. Yet, these are early compared to those photographed June 6, 2019 used in the last still life.

These first photographs were taken with a Canon EOS 5D Mark IV dslr, new for me as of 2020, fitted with a 600EX-RT Speedlite (flash) and the Canon EF 70-300 mm (variable) f/4-5.6L USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head.

Our Itoh yellow tree peony has flowers on stalks too slender to hold the heavy blooms upright. The flowers open hidden among thick leaves. Here they are a still life of cut blossoms and leaves. The cultivars of Paeonia, the mouton, or hua wang, king of flowers, are ofe of the classic ornamental genera of China. By the 11th and 12th centuries the center off cultivation was in Sichuan, and there yellow-flowered varieties appeared.

Crossbreeding of yellow-flowered P. delavayi with traditional double-flowered P. suffruticosa cultivars by Victor Lemoine in Nancy, France has led to the introduction of the color yellow into the cultivated double-flowered tree-peonies. These hybrids are known as the Paeonia × lemoinei group. In 1948 horticultulturist Toichi Itoh from Tokyo used pollen from ‘Alice Harding’ to fertilize the herbaceous P. lactiflora ‘Katoden’, which resulted in a new category of peonies, the Itoh or intersectional cultivars. These are herbaceous, have leaves like tree peonies, with many large flowers from late spring to early autumn, and good peony wilt resistance. I am guessing our Yellow Wooden Peony is a type of this hybrid because the long stems are more herbaceous than woody, the heavy flowers droop so the best form to capture them is the still life.

Compare the above two exposures to appreciate the effect of the f-stop and excellent bokeh of the Canon “L” lens.

This still life from the 2019 bloom was taken with a Canon EOS-1Ds Mark III dslr and the Canon EF 50 mm f/1.2L USM lens used above. Stabilization provided by a Manfrotto 3036 (studio) tripod with the 468MG hydrostatic ball head. That room is bright from large, east-facing windows. Late afternoon light is soaked up by the black velvet backdrop leaving the lemon yellow leaves to shine.

Woody Peony 50 mm

An Early Spring for 2021

Spring 2021, though cold, is early. As I write this the peony blooms presented here, photographed May 20, 2021 are seeding, the gorgeous purple magenta petals strewn beneath the woody stems. In my last posting, from Memorial Day 2019, the plant is in full bloom the end of May.

These photographs were taken with a Canon EOS 5D Mark IV dslr, new for me as of 2020, and the Canon EF 50 mm f/1.2L USM lens stabilized with the Manfrotto BeFree Carbon Fiber tripod with ball head. Color results from the Canon dslr are impressive, the first time the unique purple magenta is accurately represented here. I found a slight under exposure captured the plum – fine burgundy wine nature of this Japanese cultivar, “Shimadaijin,” planted in the 1970’s or 1980’s.

Here is the last unopened bud of this season, enclosed by a calyx of 5 green sepals with reddish highlights . In the wild, woody (also called tree) peonies favored cliffs and scrub of western and central China, eastern Himalayas (southeastern Tibet).

The bud is toward the back, slightly out of focus, of this overview. The woody stems hold the profusion of large flowers each one erect. “Tree” is a misnomer as this plant is a shrub growing mid-thigh high. One of the classic ornamental genera of China, known there as moutan or hua wang “King of Flowers.”

Cultivation in China began in Chekiang in the early 4th century AD. By the early Tang period (circa 700 AD) hundreds of varieties were grown.

Dawson’s Magnolia?

A 2021 Blessing

The Magnolia genus has been around for eons, come characteristics are protective from beetles as they existed before bees and relied upon beetles for fertilization. Our’s may be the species Magnolia dawsoniana (Dawson’s Magnolia), it shares many of the published characteristics: among them tolerance to our hardiness zone 5, flower color and shape, tree growth pattern.

This was an exceptional year for blooms. starting late April, lasting into May. The fence around trunks is for protection against bucks (male deer), from rubbing their horns in autumn.

For most of these 2021 photographs I used the lens Canon 24 mm f/1.4L II USM, the one captioned 50 mm I used Canon 50mm f/1.2L USM. The Canon EOS 5D Mark IV dslr with the Manfrotto Studio tripod with hydrostatic ball head for all.

The last great year was 2018……

For these 2018 photographs the Canon 24 mm and Canon EF 100mm f/2.8L “Macro” lenses with Canon’s EOS-1Ds Mark III dslr.
