Toronto spring #phenology thread:

Seeing lots of flowers on the redcurrant plant, now in its fourth year since planting. Excited for the harvest.

View across a redcurrant bush, quite close in, so that not the entire bush is visible, but affording view of flowers. The bush with smallish leaves and small flowers. The flowers currently look yellowish green and hang down from the branch on small flexible stalks, about six to ten flowers per stalk. About a dozen stalks are visible in the photo.

Bottom flowers of the stalk haven't yet developed/opened so the stalk with flowers looks like it tapers down to a point, like a funnel or a narrow upside-down cone.

The photo is taken on a cloudy day and it's a tiny bit washed out. The focus is quite narrow so many of the flowers and leaves are slightly bokeh blurred. In background is a blurred backyard with other greenery and a wood fence.

Trillium in the color white. Green leaves/bracts. Plants of the forest floor in the background. “Trillium is a unique plant given it does not technically have above-ground stems or leaves. What we identify as leaves are morphologically bracts or modified leaves.“ Swihart 2023

spring isn’t as ephemeral as its flowers might have you believe, or, why I’m so obsessed with when the spring begins:

https://write.as/freeanduneasy/10-april-2025

a blue cohosh flower with leaves beginning to unfurl. The leaves look strange and almost like something dr. Seuss would draw, finger-like tendrils of green still curled tightly and not yet opened up. The flowers have deep purple petals and a yellow center.

“Harbingers of spring” (Erigenia bulbosa) flowers growing from the forest floor. The flowers have white petals and large dark-reddish anthers and are very small.

A rue anemone (or perhaps wood anemone) flower blooming from the leaf litter in the forest floor.

Some of the only Virginia bluebell flowers that were open in the entire woods. A small cluster of purple and blueish flowers, bell-shaped, and surrounded by vibrant green leaves. Some leaves have raindrops on them and there is another small cluster of unopened purplish flowers in the bottom left corner.

Trillium by the thousands today in Prairie Creek Redwoods State Park. The weather was warm enough for snakes to be out along the trails.

A warm day today in the redwood forest. Trillium were prominent, with colors ranging from white to pink to purple. This is a close-up view of a white trillium in Prairie Creek Redwoods State Park. Egg-yolk yellow anthers can be seen in the center of the flower. The shadow of the trillium falls on its green leaves.

Berberis aquifolium / Mahonia aquifolium is blooming fragrantly on campus! My neighbors cut theirs down, I’m glad I’m not totally deprived of this gorgeous native PNW plant #bloomscrolling #phenology

So great to see so many amphibians out in the park tonight. Toads and newts mainly, also heard a frog calling. Had to put on my torch to avoid treading on them, it was warm today but is now cold so they were a bit lethargic moving across the path #Phenology #Spring #biodiversity #ClimateDiary

Phenology (Climatology )

Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors. Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and...

Giant trillium, western trillium, Prairie Creek Redwoods State Park. Learn more at https://www.parks.ca.gov/?page_id=415 and https://www.nps.gov/redw/learn/nature/whenbloom.htm and #nps #nationalparks #publiclands #photography #forest #trees #flowers #phenology Image credit Kurt Angersbach / Westernlabs #california #redwood #colors

This is a close-up view of a giant trillium in red or maroon-red color. The image is from yesterday in Prairie Creek Redwoods State Park (Redwood National and State Parks). The plant was in low light and snuggled in with a variety of other plants so the image quality is less than ideal. Nonetheless, these are very interesting flowers to see, especially when one considers the size and color (frequently described as “mottled “) of the leaves as well!

The western trillium in white. The image is from yesterday in Prairie Creek Redwoods State Park (Redwood National and State Parks). Droplets of water from recent rains adorn the flower and leaves. Redwood sorrel, ferns, and other elements of the forest floor are visible in the background.

“But Thoreau also knows that the calendar, like Emerson's "tradition," has hardened into a formal and highly abstracted system, and that its present lines of demarcation are arbitrary. As categories of perception, neither the months nor the seasons, traditionally demarcated, are responsive to nature's actual currents of change because they have become distanced from perception, which no longer informs them.“

from Thoreau’s Morning Work by Daniel Peck
