Lobelia’s namesake: Mathias de l’Obel and the botanical tale of beauty and toxicity

Dearest reader,
On this day, the botanically inclined world welcomes the arrival of Mathias de l'Obel ("ma-TEE-us dew Lew-bell"), a Flemish physician whose gentle wisdom forever changed our understanding of the plants beneath our fingertips and feet.
Picture Mathias tending to his medicinal garden in England, amidst the mists and mysteries of a country eager for both healing and discovery.
What might he have whispered to his lobelias, as he meticulously observed what others had missed—the elegant distinction between monocots and dicots?
It is odd, isn't it, how the smallest nuances bloom into revolutions? The scientific split that Mathias espoused—sorting grasses from lilies, tulips from roses—still shapes garden borders and botanic books today.
Did Mathias realize, as he parsed the veins of leaves, that his work would ripple outward, touching future generations of garden lovers, one root at a time?
Today, we celebrate Mathias with the Lobelia, that irresistible confection of a flower, dazzling in shades of pink, light blue, and royal blue. Yet, one must admit, dear reader, that Lobelia’s beauty belies her sinister aliases: Asthma Weed, Bladderpod, Gagroot, Pukeweed, Vomit Wort, Wild Tobacco—the sort of names that would make one’s tea curdle if served with polite conversation.
Are these monikers not worth pondering? Why do the prettiest in our borders wear such unfortunate titles?
The answer, of course, lies in Lobelia’s potent toxicity, a reminder that the garden’s sweetest faces are often the most cunning.
Still, how enchanting it is to see Lobelia’s delicate blossoms hosting bees, butterflies, and moths each summer! Each flower becomes a miniature ballroom for pollinators, a parade of color and motion, and, dare I say, a living tribute to Mathias himself.
Each year, two flats of light blue lobelias grace the modern gardener’s containers, outshining their ominous nicknames and dazzling those who pause to observe.
And as Martha Stewart would remind us, there is wisdom in pronouncing Lobelia as "LEW-beel-ya," honoring the man whose name shaped the plant. It is a small but poignant adjustment—one that honors heritage and knowledge in the act of gardening itself.
Are we not stewards of memory when we speak a name rightly in the garden?
So, dear reader, as you plant your lobelias—light blue, pink, or royal—ask: What hidden stories pulse beneath their roots? What secrets do their toxic foliage and dazzling petals keep?
Will you, too, honor Mathias de l'Obel, and seek the subtle differences that change everything, one stem at a time?
