Tunicate bulbs are some of the most familiar bulbs we come in contact with both in and out of our gardens.
Many underground plant structures are generally named bulbs. A definition of a bulb is a plant that incorporates its entire life cycle in an underground storage unit. Technically true bulbs are compressed stems surrounded by fleshy leaves acting as food storage organs. They are in the Monocot family of plants.

Bulbs can be further classified by looking at their various growth habits. Some of these “bulbs” are actually further classified as “true” bulbs, corms, tubers and rhizomes. Examples of these bulbs respectively are: narcissus, crocus, dahlia and canna.
True bulbs are represented by two classifications, tunicate and imbricate as represented by onions and lilies in that order.
Tunicate bulbs have a dry thin paperlike sheath surrounding them which helps to prevent them from drying and improves their storage capability. The basal base plate along with the tunicate sheath hold the bulb together. Roots emerge at the bottom of the basal plate.
We enjoy these bulbs both in the kitchen and in our gardens. Our cooking is enhanced by the addition of the tunicate bulbs of onions, garlic and shallots. The joyous colors in our early spring gardens are presented by our daffodils, tulips and hyacinths.
The term “bulb” is used by most people to refer to plants that have underground, fleshy storage structures. Only some of the plants commonly called bulbs actually are bulbs. The general definition of a bulb is any plant that stores its complete life cycle in an underground storage structure. These underground storage structures store nutrient reserves to ensure the plants’ survival.
Tubers, rhizomes, corms, and bulbs actually all serve the same purpose, just in a different way. They are each a storage unit for food that gives the plant the energy it needs to grow, bloom and complete its lifecycle each and every year.
The energy is created and stored by the foliage’s photosynthesis. You’ve probably heard that it’s important not to cut back the foliage after the bloom has died. That is because the leaves need to have time to absorb energy for next year’s bloom. Each storage system takes differing amounts of time to perform this task. Examples would be Alliums and Daffodils.
Bulbs or bulb-like plants are usually perennials. They have a period of growth and flowering. This is followed by a period of dormancy where they die back to ground level at the end of each growing season.
As with perennials, there are bulbs that are hardy in our climate and others that must be overwintered as house plants or placed in dormant storage.
Bulbs can be broken down into five types of storage structures. These include: true bulbs, corms, (stem) tubers, tuberous roots and rhizomes.

Bulbs (which are referred to as “true bulbs”) grow in layers, much like an onion. At the very center of the bulb is a miniature version of the flower itself. It is composed of a shortened stem covered with modified leaves called scales. Helping the bulb to stay together is something called a basal plate, which is a round, flat area that are the beginnings of the roots on the bottom of the bulb.
Many plants such as daffodils form new bulbs around the original bulb. These bulbs, called offsets, develop from buds within the base of the mother bulb and produce new plants. When these bulbs become overcrowded, the flowers start to diminish in size. This is an indication that it is time to dig up and divide the bulbs.

My Garden and my Art go side by side. Both require me to make aesthetic judgments about composition, scale, color, texture and style. When I’m deciding where to plant the flowers I’ve hauled home on my endless trips to the nurseries it doesn’t seem that much different to me then when I’m deciding how to compose them on a two-dimensional surface.
I think about what style I’m looking for, what colors will work together, whether the scale of the placement works for me. I think about the type of flower and texture of the leaves. I make decisions about the 3D composition of the garden much like the 2D composition decisions on a painting.

The garden adds so many additional layers of complexity since the artwork is moving in time with nature, the seasons, the elements, and time. The painting remains caught in a moment.
Capturing that ephemeral moment is so gratifying to me in my Fine Art. I control it, unlike my Garden which is usually out of control.
This watercolor painting is available directly from me, Mary Ahern, as an archival print on Fine Art Paper, double matted and ready for framing.
Grape muscari, otherwise known as Grape Hyacinths live close to the ground. For years I never took much notice of them except for the little spots of brilliant purple that bounced so nicely against the bright yellow daffodils they bloomed along with in April.
Then I got down. Hands and knees down.
What a surprise! How intricate the little flowers are. Little bells dance around a central stem forming a small pyramid. This inflorescence changes shape as it ages and can be more and less tightly knit.
The individual purple doesn’t seem to change on each bell but the overall purple varies when viewed at a distance based upon the tightness of the overall flower.
I enjoyed these 4″ bulbs so much in my garden that I bought a bag of them from Costco one year and low and behold the next spring the flowers that bloomed were very different from my originals. They were more blue than purple and were more rounded than pyramidal.
So I googled Grape Muscari and found a world of cultivars I didn’t previously know existed. That’s one of the things that is so much fun about gardening. You are constantly in a learning mode. You are in for surprises every year and every season. The knowledge and information you acquire just keeps on growing, along with your garden.
So now I know that so far in my garden I have Muscari armeniacum and M. azureaum. Next year I’m sure to have more.
When I made my Digital Mixed Media Painting of my Grape Muscari I was careful to recreate the basal growth of the leaves. It would not have been accurate if I’d placed the leaves higher on the stem. The painting would have looked like a plant Frankenstein. As a Garden Artist, that is not what I’m trying to create.
You can view this Grape Muscari piece in my Store.

At midlife, taking lower pay to begin more satisfying careers
By Arlene Gross

Mary Ahern had dabbled in art for many years, but had never been able to actually make a career of it. Until four years ago, that is, when she made the switch to full-time artist.
“I had always been a creative artist,” the Northport resident, 60, explained. “Life, however, intervened, and as a single parent, I was never able to create my art on a full-time basis.”
Changing careers at midlife is no small feat, and switching to one with substantially less earning potential is more difficult still. According to Randy Miller, founder and president of ReadyMinds, an online career counseling service, downsizing a career can be a source of great anxiety.
Yet for some people, any fear or hesitation is mitigated by the yearning to follow a dream. Seeking more spiritually uplifting endeavors can be the ultimate challenge, and Miller said any attendant loss of income is often compensated with a renewed sense of purpose and newfound happiness.
“There are a lot of people who go through life and think, ‘What if?'” Miller said. “With a strategic plan, coupled with the new passion and ultimate objective of doing something different, one can more easily achieve their ultimate goals.”
For Ahern, a new husband provided the impetus and financial support to move forward. Income, the couple concluded, was less relevant to the quality of their lives than the legacy they wish to leave behind.
“When we married, Dave urged me to follow my dream,” she recalled. “The hard part at first was trying to find inside myself what that dream actually was. You spend so much time marching forward and doing what you do, you lose the essence of yourself.”
Once their five children — all from previous marriages — were finished with college, Ahern felt it was OK to follow her calling.
“My income from my art doesn’t yet come close to the money I’m used to making in either my career in computer graphics equipment sales or my own graphics design firm,” she said.
One of her greatest sacrifices was a big dip in retirement savings, which now come exclusively from her husband’s salary.
“We have a comfortable nest egg,” she said, “but by coming out of a conventional career, I no longer have the extra cushion to add to my existing portfolio of tax-advantaged savings vehicles.”
Despite her diminished earnings, Ahern says she is happier. “I am living the life I am meant to live,” she said.

Artist cultivates her livelihood like a garden

Northport resident Mary Ahern is a successful artist who practices a unique technique she describes as. “Digital Mixed Media Painting”.

But Ahern, who… (was) among the exhibitors at Arts in the Park in Northport July 8, (2007) was not born an artist. “I didn’t come to paint until I was older,” she said. “I didn’t even know I had a facility for it.”
As a young girl, she focused on music: playing trumpet and saxophone for the high school band and conducting her Fort Hamilton High School graduation in Brooklyn with a rousing rendition of Beethoven’s Fifth Symphony.
“I’ve been in the bleeding edge of those kinds of issues,” she said. “In those days, girls didn’t conduct.”
A life-changing moment came in her 20s, when a friend gave her a coffee table book of Georgia O’Keeffe’s paintings.
“I opened it up and turned the pages and wept,” she recalled. “It was completely transforming. I could only look at 10 pictures a day, it was so overwhelming.”
From that moment, Ahern knew she must study art and, then a resident of Queens, attended Queens College.
Although she was influenced by O’Keeffe and painted similar subjects, such as close-up and sensual florals, Ahern said she did not mimic her idol’s technique. Whereas O’Keeffe painted with direct and rapid strokes, Ahern’s traditional paintings were created in grisaille, or gray scale, and layered with washes of pigment on top, giving the subjects a glow through the optical blending of glazes of pigment.
After divorcing her first husband, Ahern took a job at Barnard College’s career counseling office, where she herself was able to get some career guidance. Through her Barnard position, she attended Columbia University for free by working there while raising sons, Chris and Michael, then ages 10 and 8.
“I knew if I couldn’t stay home and be a mom and paint, I had to make a decision: I’m going to make as much money as possible,” she said.
With profit in mind, Ahern went into technology sales, selling computer graphics and eventually becoming Northeast regional sales manager at Chyron Corporation in Melville. Then she started Online Design, a digital graphics company.
For Ahern, feminism was not a word to bandy about but, rather, her day-to-day reality – working as a single mother in a male-dominated industry.
“My single-minded focus on providing a good life for my sons enabled me to ignore the tremendous obstacles, prejudice, emotional assault and loneliness that comes from breaking through social barriers,” she said. “I, like my father, pulled myself up by my bootstraps. As a woman in a male industry however, I, like Ginger Rogers, did everything in high heels and backwards.”
In 1989, Ahern fulfilled her dream of buying a house with a spacious garden in Northport, which she said, “was like a step back in time to a slower and more gracious lifestyle.”
“The center of town with a Main Street embedded with trolley tracks leading to the harbor breezes and music in the gazebo captured my attention and insisted upon my attendance. I needed to move here.”
Eleven years later, she renovated her home, adding an airy, second floor art studio, and now natural light trickles throughout.
The garden, which Ahern designed, encircles the house, with its artfully designated focal points and meandering paths, everything flowing gracefully.
“I practice nonviolent gardening – no rose bushes to stab you – all soft inviting plants,” she said.
Seventeen years after her first marriage ended, Ahern married David Ruedeman, an engineer at Chyron. The couple worked together there but got to know one another only when he became a client of Online Design. This year will mark the couple’s 10th anniversary…
Early on in the second marriage, wishing to reinvent herself, Ahern got a degree in horticulture from SUNY Farmingdale in 2000, with the idea of becoming a landscape designer, which she did for a year. “It was too much for my … body,” she said, of the many hours spent working on bended knees.
From there, it was a two-year course studying botanical illustration at the New York Botanical Gardens in the Bronx.
Her (Mixed Media) painting, a culmination of expertise paralleling her life’s progressive journey, combines a passion for the fine arts, gardening, computer graphics and botanical painting.
“To be creative, you need to know your medium,” Ahern said of her computer graphics skills. Through her paintings, she seeks to make people look around them and become more aware of the nature surrounding us.
Dr. Roberta Koepfer, her friend since 1971, said, “She’s like a phoenix. I have seen her rise up from a fair number of devastating experiences. Every time she comes back, she comes back more dynamic, more focused on her art and with an increased zest for life and personal growth.”
When it came time to sell her art, Ahern’s business savvy came in handy; she started in Northport as an exhibitor at the annual Arts in the Park series (in 2004) and now participates in about 15 art shows in New York and Connecticut between May and September, with her husband lending a hand.
Ahern’s work has also been the focus of several gallery exhibitions, including a one-person show at Greenlawn’s Harborfields Library this past February.
Susan Hope, gallery coordinator for the library, noted that Ahern’s exhibit was well timed: her cheerful florals brightened the gloom of winter. “It has an eye catching appeal,” she said. “People really enjoyed it, whether they were art savvy or just seniors on their way to their meetings.”
Today, Ahern is either painting her botanicals, selling them or lecturing on the business of art at libraries or schools, although her business persona has changed radically over the years. “I did trade shows in high heels and silk suits,” she said, “now I’m doing business in Birkenstocks and shorts.”
To anyone seeking career guidance, Ahern advised, “Don’t throw away anything you’ve done because you want to transform yourself. Take the good portions, the positive elements and try to incorporate them into this new self you’re creating. That’s how I’m living my life.”
