ONE OF “perhaps the most primitive plants still in existence” and another that is a relative of Irish moss are two tenacious and odd-looking little creatures that like to inhabit my driveway and other crack-and-crevice spots. Maybe you have liverworts (above) or birdseye pearlwort at your place, too?
You know me: I like to know my weeds—rather than just have a fit about some infestation or other, to actually find out what they are, and where they are native to, and what their role for better or worse is in the bigger picture is (other than to irritate me).
I don’t know which liverwort I have, but it is what’s called a thallose species—made up of flattened tissue that looks almost rubbery to me. You might think at first they were some kind of moss or algae, and in fact like those other Bryophytes the liverworts have no vascular system, and they reproduce by spores.
Liverworts are “perhaps the most primitive plants still in existence,” says the Slater Museum of Natural History at University of Puget Sound in Tacoma, Washington.
One such thallose liverwort, the globally widespread species Marchantia polymorpha (above video), is a familiar problem on container plants in nurseries, on the potting-soil surface. It loves the moist environment with ample fertility. You may have purchased a nursery pot with this in it—look familiar?
“These plants without roots or vascular tissues for nutrient transport are living links to the transition from the algae that found its way out of the ocean to the established multitude of land plants,” says the Joint Genome Institute at Lawrence Berkeley National Laboratory, which created the video.
Liverworts are an important organism of their native habitats, but as for mine growing in the gravel here,

Hay fever and Asthma attacks can be brought on by Scented Plants as well as pollen or Fungal Spores. Histamin problems can also be exacerbated by scent and smells in the garden.
Potato blight, also called late blight, is a destructive fungal disease that is caused by spores of Phytophthora infestans. Potato blight spores are spread on the wind and may also contaminate potato tubers in the soil. It can ruin a crop in 10-14 days and there is little that can be done to save an infected crop. It was the original cause of the Irish Potato Famine.
The Rowan or Mountain Ash, Sorbus aucuparia is a member of the same family as the rose and is part of the large Sorbus genus (50+ distinctive species). They are highly variable with several regional sub species. The trees can be quite singular in appearance when shaped by wind on high moors and mountains.
Our transatlantic cousins still benefit from the Pilgrim fathers gardening knowledge taken to their shores centuries ago. The potato famine of 1845-50 caused Irish farmers to discover the Idaho potato. Now these and other horticultural favours can be returned by this book of organic homespun tips.
I nearly shared a photograph of monstrous Rudbeckia ‘Irish Eyes’ on Six on Saturday, but had too many images for it to make the cut. It is a variety I have grown from seed for six or seven years or more, but never has it grown so tall – at least 4 feet or 120cms! Not only that, but the blooms have lasted on the plants for a good month with no deadheading required, although one or two are now just on the turn. If any bloom deserved a shout-out in a Vase on Monday it is this rudbeckia and, accordingly, its blooms make up the majority of the contents of today’s IAVOM.
As health and sustainability continue to take precedence for consumers across the globe, the popularity of edible aquatic plants has shot up like never before. Enter sea moss, a sea green that addresses these concerns—and then some. Here’s what to know about its health benefits, eco-friendliness, and how to use it cooking and in all of its forms.
St. Patrick’s Day, March 17, is a popular celebration in the United States, due to the number of Americans, 10.5%, with Irish heritage. One million Irish emigrated to North America, Australia, or other parts of Great Britain in the mid-1800s because of the potato disease now known as late blight. Late blight, caused by the water mold, Phytophthora infestans, destroyed the Irish potato crops in 1845 through 1849 and caused the Irish Potato Famine. Another one million people died from hunger or disease.
If you visit your favorite garden center in late February or early March, you’ll likely find shamrock plants to coincide with the St. Patrick’s Day holiday. The myths and folklore surrounding St. Patrick are quite fascinating, although perhaps not factual.
