Icelandic or Arctic?

If you’re a gardener or flower enthusiast of any sort, you’re probably familiar with Icelandic poppies, popular in the florist trade. These are not Icelandic poppies. They’re arctic poppies.

Because the two common names seem to be tossed around with abandon, I’m going to stick with the Latin here. P. radicatum has four subspecies (according to the Integrated Taxonomic Information System), which may explain why I found conflicting data from various sources. Some claim the species is endemic to Iceland. Others claim it’s endemic to Norway and Sweden. And still others say its native range includes Iceland, Jan Mayen, and North America (Greenland, Canada and the US). Probably what’s going on here is each of the subspecies is endemic or native to a particular area.

I can’t say which subspecies this is, but for sure it’s P. radicatum: the hairy leaves and stem are the signs. This species is found in the western and eastern regions of Iceland, with a few scattered occurrences elsewhere. I saw it in the Westfjords near the waterfall Dynjandi, and in the Snæfellsnes penninsula. In the US it can be found in a few counties in the Rocky Mountain states (and in Alaska).

As for the so-called Icelandic poppy of the florist trade, that’s P. nudicaule (or P. croceum in some older sources). It’s hairless – nudicaule means “naked stem”. This species is not native to Iceland, but rather to North America. Sources disagree on its range, though. BONAP shows it as a native in part of eastern Canada only, while USDA shows it as a native in Alaska, Utah, Colorado, and Virginia, and introduced in parts of western Canada.

We did see Icelandic poppies in Iceland:

 

They grow there in gardens.

Craters and Poppies

Ubehebe Crater, in the northeastern part of Death Valley National Park, is a beautiful and fascinating geological feature, the remains of a volcanic explosion that happened only 300 to 800 years ago (estimates vary).  The crater is about half a mile wide and 600 feet deep, and there’s a trail that circumnavigates the top.

The area is covered in cinders and colorful gravel and only very few plants. Actually it was a great place to get specimen photos, since the plants grew so sparsely, and almost always well apart from each other.

I was poking about, alternately admiring the flowers and gaping at the geology, when (yet another) yellow flower caught my eye.

This is Mojave gold poppy, aka desert poppy, Eschscholzia glyptosperma (Papaveraceae).  I saw maybe half a dozen of them in a small area between the parking lot and the viewing area at the top of the crater. Note the elongated seedpod above the flowers in the photo to the right.

Apparently this poppy is common across the Mojave desert, but I didn’t see them anywhere else during my trip.
