August’s Yellow Flowers

Sunflowers_RedLionSWA-LoganCo-CO_LAH_2282

What is it with August and yellow flowers? Last week Pete and I revisited the Yampa River Botanic Park in Steamboat Springs. As I expected, the gardens were in full bloom—dazzling in the clear mountain sunshine. As I strolled the pathways, I noticed expanses of Coreopsis, clumps of Rudbeckia, beds of sulfur-yellow buckwheat (Eriogonum), and sprays of goldenrod. And that’s when I realized that the majority of blooms were in some shade of yellow.

Hope for Musically Challenged Birders (Like Me)

It’s early morning, too early, I groan, but the air is full of sound. Even before the sun crosses the horizon, I can hear the birds calling, singing, squawking, and chirping, all right outside my open bedroom window. Granted, that’s what I get for putting the feeders up close to the house, where they can easily be seen. But still—all that noise, just because dawn is coming?

As I lay in bed, I can distinguish the cooing of the pigeons from the two similar calls of the Mourning Doves and Eurasian Collared-Doves. I know that most of the noise is coming from the flock of House Finches that seem to spend all their time in our yard. And that harsh screeching means the magpies have returned.

pH for Gardeners

To a gardener choosing which plants to grow, pH is an important consideration. While the pH of most soils falls somewhere between 3 and 9, the majority of common landscape plants prefer a pH slightly on the acidic side, say 6.2 to 6.8. However, some plants, such as blueberries and rhododendrons, prefer an even more acidic soil (with a pH in the 5 to 6 range) and other plants, green ash trees and clematis, for example, do best under more alkaline conditions, with a pH above 7.

Mt. Evans, Revisited

Here in Colorado, when it’s hot out on the plains, we head to the mountains. And there’s no better mountain to head to than Mt. Evans. No hiking required, unless you want to reach the 14,265 foot peak, and even that is only a quarter mile up a series of switchbacks from the summit parking lot. And while the view from the top is worth the effort, most of the really good stuff is on the way there. It’s a good metaphor for life.

Campanulaceae: Beautiful Bellflowers, Lovely Lobelia

Campanulaceae is a family of plants with members ranging from the towering palm-lobelias of Africa to cottage garden flowers with names from a child’s book of fairytales: Canterbury bells, Cup and Saucer Vine, Harebells, and Fairy’s Thimbles. Two familiar genera, Campanula and Lobelia, are members of this family.

But Can I Repeat It?

Reproducibility is one of the foundations of science. If something is true, it should be true every time. While it’s exciting to create new studies with new results, it is equally important to recreate studies done by others.

It may come as a surprise to many that science never proves something to be true. We can falsify a hypothesis, but there is always a chance that our positive results are due to chance. Reproducing studies is one way to reduce that possibility.

Hydrangea Heaven

I just spent two weeks in the Pacific Northwest. Since our daughter and her family live there, we visit frequently, but typically at Thanksgiving or in mid-winter. This time we managed to arrive in July. What a treat! With blue skies, light breezes, and puffy white clouds, the weather was (mostly) perfect. All that rain during the fall, winter, and spring results in stunning summer gardens, with emerald green lawns and towering trees. And the flowers! Yes, the rhodies and azaleas were done, but the hydrangeas were in full bloom. Everywhere we looked, we saw huge flower clusters of bright pink, magenta, white, and most noticeably, pure sky blue.
