Biography

Deborah’s interest in orchids was sparked by a trip to Hawaii and has been under their spell for over 30 years. She started with a few plants and her mixed orchid collection expanded exponentially with the construction of a greenhouse in 2014. She joined the Windsor Orchid Society in 2013 to gain more orchid knowledge and found herself in the Presidents position six months later. She is very active member of the WOS, involved in fundraising and publicity and has recently taken on the role as Show Chair.

She is an Accredited judge in the AOS judging program at the Great Lakes Judging Center, Ann Arbor, Michigan and enjoys presenting and educating audiences about orchids. She was the recipient of the Orchid Digest Diamond Award in 2016 and invited speaker to the WOC Tainan in 2024.

Academically, Deborah has a degree in Chemistry and spent her first years of work as a researcher in medical microbiology and infectious diseases at both the University of Calgary and Foothills Hospital in Calgary, Alberta. She recently retired from St. Clair College in Windsor, Ontario, Canada, where she taught chemistry for over 28 years. She now has time to enjoy her passion for orchids, gardening, photography and travel.

Talks and Abstracts

1

Tiny Slippers aka Miniature Paphiopedilums

Miniature Paphiopedilums are not only stunningly beautiful but small enough that you just might find space to fit a few in your collection. This presentation will discuss the breeding for the perfect miniature plants, what species are used by hybridizers and showcase many of the recent miniature crosses that have been created. After this talk, you may be tempted to collect a few of these beauties at the next orchid show so, I will also talk about cultural requirements.

Sobralias The Exotic Ephemerals

Sobralias are beautiful reed like plants with exquisite flowers yet are not common in many orchid collections. This presentation will enlighten the hobbyist about this genera, the species and hybrids, where are they are from and how to grown them. Don’t be surprised if you feel the need to have a few in your collection after seeing an array of these stunning plants and how easy they are to culture.

Stanhopea tigrina The Tigress of the Mexican Plateau

Central and South America have a rich diversity of Stanhopea species, but it is the eastern slopes of the Mexican plateau that are home to one of the most alluring of them all: Stanhopea tigrina. This species’ exotic appearance and impressive size have made it both the most awarded and the most hybridized member of the genus. This presentation explores its floral morphology as it relates to the pollination process and the fragility of the relationship between pollinator and flower, an interdependence that underscores the importance of thoughtful cultivation and hybridization in preserving the species. Hybridizers have relied on tigrina for decades in the pursuit of striking, award‑winning progeny. What makes Stan. tigrina so popular, so decorated, and so influential—as well as the traits it reliably passes on to its hybrids—will all be discussed, along with practical cultural guidance to help growers succeed with this remarkable orchid.

Orchid Expedition on the Rio Negro, Brazil

A captivating journey deep into the Amazon rainforest—this presentation chronicles my orchid expedition along the Rio Negro aboard the Otter Houseboat. Beginning in Manaus and winding through the river’s remote tributaries, the journal follows days spent spotting monkeys, sloths, parrots, macaws, and of course, orchids in their native habitats. Organized by the Orchid Conservation Alliance, this trip offered an intimate look at the Amazon’s extraordinary biodiversity. Join me as I share the discoveries, surprises, and unforgettable moments from this remarkable adventure.

Tolumnias: Small but Mighty

These tiny equitant orchids may be small, but they produce remarkably delicate flowers in an impressive range of colours and patterns. Their compact size makes them ideal for indoor growers, perfect even when space is limited and as an added bonus, they’re wonderfully easy to grow and bloom. In this presentation, I’ll explore the species most often used in hybridization, showcase some of the most striking modern hybrids, and outline the cultural requirements that help these charming miniatures thrive.

The Allure of Paphiopedilum sanderianum and its Hybrid Legacy

This can be done as a two part series or condensed into one 45-50 minutes presentation. Few orchids command attention quite like Paphiopedilum sanderianum, a species whose impossibly long, ribbon‑like petals and dramatic presence have made it a legend among slipper orchid enthusiasts. This presentation explores the irresistible allure of this extraordinary species—its discovery, its mystique, and the traits that have made it one of the most coveted plants in the genus. We’ll also trace its hybrid legacy, looking at how breeders have used sanderianum to create striking new lines that carry its elegance forward in surprising ways. And because growing this species can feel intimidating, I’ll also cover its cultural requirements, showing how thoughtful care can bring out the very best in both the species and its hybrids.
