Looking down

with 33 comments

The portrait you recently saw of a bluebonnet looked up at its subject. On the same February 29th outing along the Capital of Texas Highway by the Arboretum I looked almost straight down at an Indian paintrush, Castilleja indivisa. The red elements are all bracts, not petals; the actual flowers are small and inconspicuous.

Snow-on-the-Mountain Inflorescence from Above 7046

Most of the prominent brightness in yesterday’s photograph came from the white-margined (marginata) bracts of Euphorbia marginata, a species known on account of that whiteness as snow-on-the-mountain. As I understand it, the five-segmented white collars aren’t technically part of the plant’s flowers, nor are the smaller five-segmented dull-green collars within the white ones. Only the nondescript little elements at the heart of those concentric rings comprise the flowers. Geyata Ajilvsgi notes that there are “30–35 male flowers and one female flower congested in [each] small, cuplike structure.” If that works for snow-on-the-mountain—and it clearly does—then who are we to knock it?

This downward-looking view comes from August 29th along US 183 in Cedar Park, a rapidly growing suburb just to the north of Austin.

Snow in Texas in August

Snow-on-the-Mountain Flowers and Bracts by Pond 7661

Okay, so afternoon temperatures are still in the 90s (30s C), but by the week before last the snow-on-the-mountain plants (Euphorbia marginata) in central Texas had already begun flowering. I photographed the ones shown here alongside a pond in the town of Cedar Park yesterday. All the attractive white comes from bracts; the inconspicuous flowers are much too small to see unless you get a lot closer.

Snow-on-the-prairie not on the prairie

Snow-on-the-Prairie Flowering 5091

All right, so the Blunn Creek Preserve in south Austin isn’t a prairie, but there on September 14th I found this happily flowering snow-on-the-prairie, Euphorbia bicolor. You don’t have to speak Latin to recognize that the two colors the bicolor refers to are green and white.
