I hadn’t planned on spending any time botanizing… and yet, these interesting plants kept appearing and reappearing. Our guide Elis had a folding brochure with some of the very most common and conspicuous plants of Iceland, but midway through the trip I felt the need to pick up Hörður Kristinsson’s Flowering Plants and Ferns of Iceland (2017, 3/e), with entries for 465 species (including 17 for genus Saxifraga—go figure). With the brochure, I quickly learned to recognize Yarrow (Achillea millefolium) (Vallhumall), the non-native invasive Nootka Lupin (Lupinus nootkatensis) (Lúpína), and Garden Angelica (Angelica archangelica) (Ætihvönn), a truly preposterous-looking plant.
But, provisioned with Hörður, I went looking for more. Some of the following IDs are rather provisional.
This bushy prostrate plant, with flowers gone by, was very common, and the first to catch my eye: possibly Alpine Lady’s-mantle (Alchemilla alpina).
The next day, on the grounds of our hotel in Hövn, Lady’s Bedstraw (Galium verum), a mystery plant with purple tepals, Mother of Thyme (Thymus praecox), and unmistakeable Harebells (Campanula rotundifolia) (Bláklukka).
Equipped with a search image from Elis’s brochure, I spotted something interesting and hopped off the bus in Djúpivogur to get a quick snap of the lovely daisy-like Sea Mayweed (Tripleurospermum maritimum).
So, Heather (Calluna vulgraris) is actually a thing.
In the north, at the Ásbyrgi nature reserve, peely-barked Downy Birch (Betula pubescens).
Nevertheless, there are lava fields that are in the very slow process of being overrun by lichens, mosses, grasses, creeping flowers, and taller things. I took a morning walk around our hotel at Mývatn. All sorts of green things happening. Shrubs sheltering in the potholes.
