Travel Story - Landscapes of a Cruise Down the Columbia River

I took a river cruise (with Lindblad/National Geographic) down the Snake River from Lewiston Idaho to the Columbia River to its mouth on the Pacific Ocean west of Portland, Oregon. Many interesting places went by while in the bus or on the ship. Here is a tour: the trip through the window. 

My husband and I flew to Spokane, Washington, so the trip actually started with a bus ride 100 miles south to Lewiston, Idaho. It was April 7, a cloudy early spring day in Spokane.  There is a spectacular city center I hope to walk through one day.

Growing Natives in Colorado

 There is a national push for homeowners in the U.S. to grow plants native to their area (see previous posts  part1; part 2; part 3; HNPwebsite). The number of birds and insects have been dropping over the last 50 years. Lack of food is blamed because we replaced native habitat with lawns and parking lots. Rewilding our neighborhoods is not a realistic solution; what is suggested is that we each grow regional natives on our properties, making our yards contribute to local habitat.

in Denver, though the distance is only 50-60 miles.

What to grow in Colorado is a challenge. First, Colorado has unique native wildflowers, so advice from the coasts is often misleading. Second, Colorado is complex, with natives changing as you go up in elevation, over the Continental Divide, or from north to south; getting really local information is difficult. 

Strawberries, Fragaria, Beloved Fruits. 2. Uses and Folklore

Strawberries are popular fruits, eaten world-wide. This is despite the fact that fresh strawberries do not improve after harvest and cannot be stored for very long. So popular are they that we have bred them to produce fruit throughout the growing season, not just briefly in June or July, and ship them from warmer climates or big greenhouses for year-round fresh strawberries, and we freeze them or preserve them as jams and jellies to them always available.

Plant Story -- Strawberries. Fragaria, Beloved Fruits 1. Distribution and Botany

Strawberries, genus Fragaria in the rose family, Rosaceae, are a popular fruit and have been for millennia. Twenty to 24 species are recognized, with cultivated strawberries adding many hybrids and varieties. They are native around the world, mainly in the northern part of the Northern Hemisphere, plus a few Southern Hemisphere species.

Polyploidy Part 3. Patterns in Nature: Speciation

 Polyploidy is whole genome duplication, when all the chromosomes and so, all the genes, of an organism double. In plants, it is very common; easily 3/4 of plants are polyploid.

Because polyploidy is a genetic effect that takes place inside the cell's nucleus, it is not casually observed. But botanists discovered polyploidy as soon as they had microscopes to look at the contents of the nucleus and when they tried crossing polyploids and got results that didn't make sense based on diploid genetics. (Diploid = 2 copies of the genome, polyploidy = numbers over 2, like 3, 4, and 6  see previous posts in this series link link). Study of polyploidy began in the early 1900s.

Plant Story--Catnip, Nepeta cataria, a Well-Known Weedy Herb

 Catnip, Nepeta cataria, is one of the better-known little herbs because it is a drug for cats. Cats respond to catnip for about 15 minutes, with distinctive behaviors from rubbing on their faces and rolling in it to grooming and salivating. Young kittens do not respond and some adult cats never do. On the other hand, the response is widespread among cats of all kinds, lions, tigers, cheetahs, lynx, pumas and so on, but not dogs or rabbits or rats or other groups of animals. Since cats are common pets, people provide or grow catnip for them, with the result that catnip is known to many people.

April in Tokyo

Here is a photo album of pictures from Tokyo in April. Beautiful spring flowers.

The photos are from April 2017 but if you hurry, you could still get there to see what it is like in 2024:

Polyploidy Part 2. And Crop Plants

Polyploidy is whole genome duplication, where all the chromosomes double. Animals rarely survive major chromosome changes, but plants usually do, leading to aspects of plant genetics that are quite different from animals.

Even though you cannot easily spot a polyploid by looking at it, polyploidy is not obscure. Many common, important plants are polyploid, for example bread wheat (Triticum aestivum), white potatoes (Solanum tuberosum), coffee (Coffea arabica), sweet potatoes (Ipomoea batatas), strawberries (Fragaria x ananassa) and cotton (Gossypium tomentosum). Researchers estimate that 75% of all plants, and likewise, 75% of crops, are polyploids.  

Still Winter? More Flowers!

It is still winter for me. The ground is brown and cold. Oh, I can see a trace of green in the lawn and a new shoot or two on the iris, if I look carefully.  My snowdrops and crocuses are out of the ground, but not yet flowering. So, here are photos of summer flowers for cheer. Just a few more months...

Polyploidy, Multiple Copies of the Genome. Part 1. Basics

One peculiar characteristic of plants, not much shared by animals, is polyploidy, multiple copies of all the chromosomes. In plants and animals, DNA, the genetic material, is bound up in protein-wrapped bodies called chromosomes. Organisms have several to many chromosomes, usually as pairs. For animals, each species has a characteristic number--humans 23 pairs, dogs 39 pairs--with very little variation. One of the ways that plants are DIFFERENT is that chromosome number can vary a lot, between species but also between plants of the same species growing next to each other.

Plant Story--Sambucus nigra, Black Elderberry Uses and Folklore

Since prehistory times, humans all over the world have collected black elderberries, the fruit of black elder (Sambucus nigra, viburnum family, Viburnaceae) (see previous post: link). The plant has been used medicinally for that long as well. In addition, it grows into a nice tree, 20, sometimes 30, feet tall, with useful wood. The leaves were used as insect repellents. Folklore abounded, some protecting the plant, some considering it accursed. My herbal, traditional, and folklore books have long sections on elder. Here is a selection of what they say.

Plant Story--Sambucus, Elder or Elderberry, Widespread Tasty Berry

Species in the genus Sambucus are called elder. That somehow doesn't sound right to my eastern North American ear, so I always say elderberries. That name I prefer is clearly weird--the tree doesn't always have berries, or the berries are just the fruit of the elder--but I'm not alone in this speech pattern, you can see it in a lot of U.S. writing. Historically and properly, it was elder, but bear with me, I keep sticking -berry on the name.

Elderberry with berries

They are shrubs or small trees with richly green long divided leaves. They produce big clusters of small white flowers that turn into brightly-colored berries.

Flowers, Since its Midwinter

 It has been snowy and cold, icy and cold, windy and cold, and just cold the last week. So here are so plant photos to remind you of warmth.

Travel Story--Royal Botanic Garden, Edinburgh

It was a rainy September day two years ago when I visited the Royal Botanic Garden in Edinburgh. We walked from our hotel, down old streets and past local markets.

Plant Story--Lovely Fernbush, Chamaebatiaria millefolium

The plant I call fernbush is an American shrub native to the U.S. west, from eastern Oregon and Idaho south to California and New Mexico. It grows to be about 10 feet tall, spreading to 10' wide. It has leaves with lots of divisions, hence the name fernbush, with a rich spicy scent. The flowers rise in spikes of white flowers with yellow centers. The USDA plants data base calls it desert sweet. An older plant book called it tansybush, because the leaves look like, and smell a little like, the garden plant tansy (Tanacetum vulgare).

Botanical Garden Observations

Botanical gardens are zoos for plants; places where plants from around the world are conserved. Frequently they are public but they do not have to be. Frequently also the staff conduct research on topics relating to plant propagation and identification.
