Vibrant Blooms of Zinnias and Gazanias at Cornell Botanical Gardens

Join me in admiration of these Zinnias and Gazanias at the Cornell Botanical Gardens, highlighting their vibrant beauty and rich botanical history.

As I stroll around the Nevin Center at the Cornell Botanical Gardens, my eye is drawn to a bed of bright, cheerful flowers that seem to beam with personality. Here, amidst the lush plantings, Zinnias and Gazanias bring their vivid colors to life, each bloom a tiny celebration of nature’s artistry. These flowers, from a family spanning two continents, share a surprising harmony that only the language of color and form could convey.

The Zinnias (family Asteraceae), little fireworks exploding in hues of yellow, red, pink, and orange. They belong to the daisy family, which includes many well-known wildflowers and ornamental plants. Native to the warm regions of Mexico and Central America, Zinnias were first documented by Dr. Johann Gottfried Zinn, an 18th-century German botanist. Dr. Zinn initially set out to study human anatomy, but he turned to botany after inheriting the job of garden inspector at the University of Göttingen. His study of these cheerful flowers was eventually immortalized when the genus was named in his honor. Every time I see a Zinnia, I think about Dr. Zinn’s unexpected journey into botany and how these resilient, sun-loving flowers carry on his legacy.

Growing alongside them are Gazanias (family Asteraceae as well), which, despite their similarity in form, come from an entirely different part of the world. These stunning blooms are native to South Africa, thriving under the intense African sun. Also known as “treasure flowers,” Gazanias have radiant, striped petals that look like they’ve been painted by hand, with shades of fiery orange and deep red. The name Gazania honors Theodorus Gaza, a 15th-century Greek scholar who translated many important botanical works from Greek into Latin. I can’t help but feel that these flowers, with their bold, jewel-toned colors, live up to the name “treasure,” each one a small gem in the landscape.

As I stand here, admiring these blooms, I’m struck by the way they bring a sense of vibrancy and warmth to the Nevin Center. Both Zinnias and Gazanias are sun-worshippers, thriving in full sunlight and well-drained soil, making them ideal for this bright spot. Their colors seem even more dazzling against the verdant greens of the surrounding plants, and they attract bees and butterflies, adding another layer of life to this already lively space.

In a way, the planting here feels like a dialogue between continents, with the Zinnias representing the New World and the Gazanias embodying the spirit of Africa. It’s a conversation that reminds me of the global heritage of our gardens, how each plant carries a story, a name, and a lineage across borders and centuries. Here at the Cornell Botanical Gardens, they’ve found a new home, far from where they first bloomed, but as vibrant as ever.

I leave the Nevin Center with a sense of joy and gratitude for these botanical ambassadors. Zinnias and Gazanias, each named for pioneers in botany, remind me that discovery often comes in unexpected forms, just as beauty does. They teach us to look closely, to celebrate color and form, and to appreciate the living history all around us.

Epiphyte

Discover the enchanting world of Epiphyllum, where the “Night Blooming Cereus” thrives without soil, capturing moisture and nutrients from the air. Explore its unique beauty and ecological significance. Read more to delve into this fascinating plant’s story.

The Epiphyllum genus, which includes my “Night Blooming Cereus,” consists of epiphytic plants. The term “epiphytic” comes from the Greek epi- (meaning “upon”) and phyton (meaning “plant”). Epiphytic plants, sometimes called “air plants,” do not root in soil. However, this term can be misleading, as many aquatic algae species are also epiphytes on other aquatic plants (seaweeds or aquatic angiosperms). Therefore, it’s essential not to confuse the genus root word “phyllum” (leaf) with the generic term “phytic” (plant), even though they share the common prefix “epi.” A plant can be epiphytic without being part of the Epiphyllum genus.

These were captured with the Canon EOS 5D Mark IV dslr on a Manfrotto tripod.

An epiphyte is a plant or plant-like organism that grows on the surface of another plant, deriving its moisture and nutrients from the air, rain, or debris accumulating around it. The host plants on which epiphytes grow are called phorophytes. Unlike parasites, epiphytes use other plants merely for physical support and do not negatively impact the host. Epiphytes can also be called epibionts when growing on non-plant organisms. Common in both temperate zones (mosses, liverworts, lichens, algae) and the tropics (ferns, cacti, orchids, bromeliads), epiphytes enhance biodiversity and biomass in their ecosystems. They make excellent houseplants due to their minimal water and soil needs and create rich habitats for various organisms, including animals, fungi, bacteria, and myxomycetes.

Epiphytes are not connected to the soil and must source nutrients from fog, dew, rain, mist, and decomposing organic material. They have an advantage in the canopy, where they access more light and are less vulnerable to herbivores. Epiphytes also benefit animals that live in their water reservoirs, like some frogs and arthropods.

Epiphytes significantly affect their host’s microenvironment and the broader ecosystem. They hold water in the canopy, reducing soil water input, and create cooler, moister conditions, which can decrease the host plant’s water loss through transpiration. Non-vascular epiphytes, like lichens and mosses, are particularly efficient at rapid water uptake.

Keuka Terroir

Pam and the author visited Dr. Frank Winery on Keuka Lake’s west side, observing how local environment and genetics, particularly epigenetics, influence vine growth. The west side has more sunlight exposure, due to geological conditions creating a microclimate favorable to the vines.

Red Near and Far

Yesterday, Pam and I headed to the peneplane behind our home to enjoy the Finger Lakes terrain graced by fall colors.  The day before I noticed the Japanese Maple leaves had turned from maroon to vermillion.  While waiting for Pam to get ready, I capture the following two shots.

This tree was planted by my father and mother in-laws.  Developed over the centuries by the Japanese, specimens reached England in the 1820 and spread from there.  It is not strictly accurate to call the color vermillion, since cinnabar finely ground produces the pigment for which the color is named, when the sun strikes the leaves vermillion is a metaphor for the impression made.

The scientific name for these trees is Acer palmatum with common names Palmate Maple (for the shape of the leaves “like a palm tree”, as for the scientific name), Japanese Maple or Smooth Japanese-Maple (for the bark).

We drove under the clouds, enjoying the rare dramatic shafts of sunlight and I gave up, finally, tying to time my shots.  Here is the view from Connecticut Hill.

The previous photos were taken with a hand held Sony Alpha 700 with variable lens.  The next two are with an Apple iPhone I had a hand when Pam and I returned home for a walk around the neighborhood to witness the transformations.

We were surprised by this orange maple, never recalling this shade before.  Like our Japanese Maple were assume it is a non-native ornamental.

Our Japanese Maple is a challenge to capture photographically as it grows beneath a larger “nut” (don’t recall the kind at the moment) tree.  We are working together to improve that, so I don’t have an overall photograph.

Here is our neighbor’s Japanese Maple.  They have a story of carrying this tree, as a sapling, on the bus from Long Island.   I love the impression of dark limbs among the clouds of red foliage. 

RedNearAndFar-3

This photograph (the “far” of the “near and far”) is from a remote corner of Chiricahua National Monument, during the trip mentioned in my post, “History and Ghosts of the Triangle T Ranch”.  To get there, I drove over a mountain pass to a location was featured in an “Arizona Highways” I read long ago.

I call this photograph “Red Dragon,” the formation is known as a “maple “

dragon”, from the long sinuous form of the tree limb.  Known for this reddish orange autumn color, this is a Big Tooth Maple, AKA Canyon Maple.  Scientific Name Acer grandidentatum (as in “big tooth”).  It is a wild specimen, living along the north fork of Cave Creek.  It is a area well know to avid bird watchers and ornithologists.
