Lichens have recolonized some urban areas following reductions in air pollution. These reurbanized lichen populations are ideal models of urban evolution. This image shows several urban lichens, including Physcia millegrana and Candelaria concolor, growing on an oak tree, Quercus rubra, in Long Island City, New York. See Ann M. Evankow et al.—Urban lichens as an emerging model for urban evolution, in this issue. (Image credit: Ann Evankow.)

The last flowers on my last #camassia. This one is called ‘Sweet Candle’. I planted several different camassia species and cultivars under the grass in a damp part of the garden. It got so boggy over winter I thought they might rot but most came up so I’ll add more this year.

Vibrant Camassia leichtlinii (great camas) with visiting Bombus vosnesenskii (yellowfaced bumblebee).

Triteleia grandiflora near a forest edge. A favorite (and edible) wildflower.

Blue star flowers of Frasera albicaulis. 💠

Vibrant indigo-blue & violet toned camassia leichtlinii bloom under a late April sunset. In addition to its beauty, camas is a valuable native food plant. 💙💜

I was at the right place at the right time. The sunrise was perfect! #wildflower

On #FridayBee #beefriday. I’m excited to share that we found at least a dozen Red tail #bumblebeequeens feeding on the #camassia on a #bumblebeesafari @yeoorganicgarden
#BombusLapidarius was 1 of the worst affected BBs last season. I had not seen a single example. we hit the jackpot! Still BUZZING!

Good Afternoon #bluesky
First time of growing the beautiful #camassia 💙 #flowers 🥰 #gardening #ourwildlifegarden

Good morning! The first handful of harvest for the season is Camassia l. Caerulea. I think they can look untidy after the blooms are finished but loving the color. #flowers #camas #camassia #nativeplant #flowerfeed

A white Camellia bloom, tinged with yellow and the odd pink stripe, rests against the glossy green leaves of the shrub in the morning sunlight.

A white Camellia blossom has turned almost yellowy-brown as it fades before dropping to the ground. At the corner of one petal on the lower left there is a pink section. The flower rests against the glossy green leaves of the shrub in the morning sunlight.

Pink and white apple blossom catches the early morning sun. To the left, the bright pink buds of more blossoms are ready to unfurl.

The purple spiked flowers of a Camassia begin to unfold from the tall central stem of the plant. To the right a wooden garden fence and gate cast shadows in the morning sun. The sky is blue in the background and just to the left of the plant you can glimpse the blurred sign of our village pub.
