Dye Plant--Sawwort, Serratula tinctoria, Obscure Historic Yellow Dye

I like rescuing plants. You know, taking a sickly little plant, giving it good light and regular water and watching it recover. My relationship with sawwort began that way. 

I was new to Colorado in fall of 2006 and finding plants for the yard of my new house. So I was looking on the end-of-the-season garden racks for promising marked-down perennials at McGuckin's Hardware Store in Boulder ("Colorado's Favorite Store"!). I chose a pot or two and got chatting with the clerk. She pointed me to the edge of the garden shop where a couple of run-down, sad-looking plants slumped over the edge of their pots and said I could have them, no charge. How could I resist?!

Visiting Denver--The Denver Botanic Garden, the Plants as Art

Dale Chihuly's glass art, in the Denver Botanic Garden until November 2014, is very much worth seeing, but when it is gone, the plants will still be there. Influenced by Chihuly's glass, I looked at the plants and saw some fantastic shapes and colors--

Visiting Denver--Chihuly Art at the Denver Botanic Gardens

The Denver Botanic Gardens are  a glorious place.

Right now there is an art display of Dale Chihuly's glass sculpture throughout the garden.

The art makes me think about gardens and art: plants are beautiful without sculpture--in the next blog I have pictures of plants from the Denver Botanic Garden that same day, seeing it as "great art, by Nature." (link)

But the Chihuly pieces are a "must see" while they're in Denver (until Nov. 2014). I like some very much, for others I thought the garden more beautiful before they were added. And so it was great fun.

Visiting the Faroes--Grass-covered Hills and Marsh Marigolds in the Sheep Islands

The Faroe Islands are in the North Atlantic, between Norway and Iceland. (See map. ) I visited them about the first of June on a tour with the Metropolitan Museum of Art, organized by Academic Arrangements Abroad. There are 18 islands, 17 with at least one inhabitant. 

It was cool and raining when we arrived. On the same latitude as the middle of Hudson Bay, the Atlantic's Gulf Stream keeps the temperatures mild. Average highs are about 51 ( 11 C) in summer and 37 (3 C) in winter. It rains more than 16 days a month all year round, though the rain may be a passing shower or a day of drizzle. Total annual rainfall varies between islands but in the capital, Tรณrshavn, it is about 50" (1280 cm).

Visiting Southern Colorado--the Great Sand Dunes

Great Sand Dunes against the mountains
I have seen sand dunes--Jockey's Ridge in North Carolina, Sleeping Bear in Michigan, the Nebraska Sandhills--so although I put the Great Sand Dunes near Alamosa, Colorado on my "to see" list, I didn't expect to be impressed. 

I was.

The road out of Alamosa takes you northward in open sagebrush country. The mountains draw closer. At some point you realize that the light area at the base of the mountain is a sand dune!

It's a beautiful area:

I don't have pictures of the Visitor Center, but it was large and full of helpful information.

We walked from the parking lot by the dunes toward the Great Sand Dunes. We didn't realize that Medano Creek ran between us and the dunes. In retrospect it seems obvious that streams wander around sand dunes when they can. The Platte River runs along the south edge of the dune system that is the Nebraska Sandhills.

The information in the Visitor Center pointed to Medano Creek as part of the attractions. The interplay of running water and the sand it carries results in the stream repeatedly damming itself with dropped sand and then breaking through its little dams. Very cool. And of course children of all ages can play in the water and sand.

The scale of the Great Sand Dunes swallowed the people.

A dune is always a contest between plants which try to grow there and the forces of erosion that keep the sand moving and plant-free. If it is wet or the winds are light, plants invade. Drought, heat and strong winds evict the plants.

We were there in mid June. The Great Sand Dunes are at 8,200 feet (2,470 m) and the Sangre de Cristo Mountains behind them are even higher. So although the sun was bright, the wind was cool: a very pleasant experience. I was prepared for the dunes to be a furnace, and they probably are some of the time, but not when I was there.

The Wilderness Area beyond the dunes beckoned us to explore, but we hadn't allowed time for that. Soon!

Wandering Plants -- Coconuts of Medieval Iceland!

A coconut in Iceland? in the Middle Ages?

I'm sure I could find one in the market in Reykjavik today. Coconuts are tropical but lots of tropical things are traded all over the world. For example, Icelandic chocolate is a favorite across all Scandinavia.

However, looking back into history, travel was slow and often difficult. Coconuts are native far, far from Iceland. 

Coconuts are the seeds of the coconut palm, Cocos nucifera (palm family, Arecaceae). Palms, like bananas and bamboo, are not strictly trees, because they do not form wood. The tough and flexible coconut palm trunk is made of the very tightly overlapping bases of the large leaves. Coconut palms can grow 80’ (24 m) high.

Plant Story -- Colorful Columbines, Aquilegia

Everybody knows columbine, right?

Columbines, Aquilegia species, are distinctive plants related to anemones and buttercups (in the buttercup family, Ranunculaceae). 

Actually, where you live makes a big difference to what you think a columbine looks like. In eastern North America, there is only one native columbine, Aquilegia canadensis. It has red sepals and spurs on the outside with yellow petals, stigmas and stamens inside. Click on the LINK !

The situation in Europe is similar. There is one common columbine, Aquilegia vulgaris. It has blue to purple sepals with white petals, stigma and stamens. Click on the LINK ! There are almost 20 rare columbine species in the mountains of Europe, but A. vulgaris is far the most widespread. In Latin, “vulgaris” means common, so the common European columbine is aptly named.

If you live in either of those areas, you are likely to have a particular image of columbine in your mind.
