Garofanino d'acqua (Epilobium hirsutum L., Onagraceae)

[stopandlook]

Scientific Name: Oenothera speciosa Common Name(s): Pinkladies, pink evening primrose Family: Onagraceae (evening primrose) Life Cycle: Perennial Leaf Retention: Semi-evergreen Habit: Forb USDA L48 Native Status: Native Location: Plano, Texas Season(s): Spring

I’m, like, irrationally obsessed with these sepals.

One peculiar characteristic of Oenothera flowers is the tendency for their sepals to fuse at the tips, forming a pennant to one side of the stem. And I think the ones in this particular patch have more swag than usual. Instead of just plain green, these are injected with yellow (chartreuse?) and bordered with sharp red stripes so they really stand out. It’s like someone who is traditional enough to wear regimental ties yet chic enough to toss them insouciantly to one side. Oh, so good.

Another Year of Pollination: Viscin Threads

While we’re on the subject of pollen-gluing mechanisms, there is another material apart from pollenkitt that a limited number of flowering plant families use to link their pollen grains together. It functions, much like pollenkitt, by aiding in the attachment of pollen to visiting animals. However, unlike pollenkitt, it isn’t sticky, oily, or viscous, and is instead more like a series of threads.…

#2319 - Epilobium pernitens

pernitens means 'shining' - presumably a reference to the glossy leaves.

A compact, creeping herb forming dense patches up to 50cm across Found in the same mountains and islands as Epilobium glabellum, but on moist slopes, usually above the bushline but occasionally lower in open springy meadows.

Epilobium canum

This plant is commonly called "California fuchsia", and although it belongs to the same family as Fuchsia (Onagraceae), it is not actually in that genus. It is common in much of California, and it also occurs in other western states of the USA, as well as in northwestern Mexico. It is much admired for the blaze of red it brings in late summer, after many other native species have finished flowering.

Garofanino maggiore (Chamaenerion angustifolium (L.) Scop., Onagraceae)

[stopandlook]

Scientific Name: Ludwigia octovalvis Common Name(s): Mexican primrose-willow Family: Onagraceae (evening primrose) Life Cycle: Perennial Leaf Retention: Deciduous Habit: Forb USDA L48 Native Status: Native Location: Plano, Texas Season(s): Summer

In spite of its common name, this plant is widely distributed in the world’s warmer regions and is considered native in the southern parts of the U.S. The reddish seed capsules here are about 2″ (50 mm) long, and their size distinguishes L. octovalvis from other Ludwigia species found nearby with similar-looking flowers. The white flowers in the background are swamp smartweed (Persicaria hydropiperoides).

Tea Time: Fireweed

lf you’ve seen one fireweed, you’ve probably seen several. As an early successional species, growing in large numbers across a vast amount of space is kind of its thing. Any disturbance that leaves bare ground in its wake, such as a wildfire or a windstorm, gives fireweed the opportunity to colonize. It grows quickly and spreads via rhizomes, producing thousands of airborne seeds in the process,…
