Time Out

Desert Boy and I are off for a few days to visit some family, and somehow I just didn't get the Plant a Day posts ready for when we're gone. It's funny how it gets so busy this time of year! Anyway, we'll be back soon, and in the meantime I encourage you to try some of the links in the sidebar.

Flatbud Pricklypoppy-Argemone munita

This long-blooming white flower with the papery thin flower petals and the prickly stems and leaves is flatbud pricklypoppy (Argemone munita), the only member of the Poppy Family (Papaveraceae) in this area. It is native to the western United States and grows often in disturbed areas, such as along roadsides.
 
Nestled among the white petals is a yellow clump of 150-200 stamens, with a maroon stigma appearing right in the middle. 

The flower buds are also prickly.

Here's a closeup of some of those prickles on the stems and leaves. They deter animals from eating this plant.

Parry's Primrose-Primula parryi

This striking magenta flower found at higher elevations and often near water is Parry's primrose (Primula parryi), a member of the Primrose Family (Primulaceae). 

Most of them have finished flowering for this year, leaving the leafy vegetation behind.

But I looked all around and managed to find a few flowers still hanging on. This flower lends so much color to the sub-alpine and alpine scenery. It also stands out because it is so large compared to much of the higher elevation vegetation, much of which has shrunken in size to deal with the harsher growing conditions.

This species grows in dry areas and is Threenerve Goldenrod (Solidago velutina), a member of the Sunflower Family (Asteraceae). It's native to the western United States.
