I did my PhD at the University of Illinois Urbana Champaign, which has more Chinese students than any other US university. I had the privilege of teaching and collaborating with Chinese students there.

This makes me indescribably angry for them and for all of us who benefit from our work together

“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

A small (2”-3”) Haworthia along a garden path in early October. Unfortunately, it’s not labeled but from the size and leaf characteristics it appears to be a herbacea or reticulata. The distinctive bright yellow bloom makes an outsized statement in the garden. 🌱 #succulents
Howarthia with a yellow bloom tucked between small boulders. This is the second time I've noticed it blooming over the past half dozen years. It's hardy to at least 30 degrees, has no problem with our heavy winter rains.

Found this striking, 2-3” solitary volunteer growing in a lightly irrigated area partially shaded by a Toyon and tucked amidst Mangave, Agave and Euphorbia. Has coloring similar to Haworthia or Gastor-Aloe but the stem is not stout more like a flower stem, perhaps some NorCal native? 🌱 #succulents
Small unidentified plant or flower spotted brown with a yellow background growing in rocky, well-draining soil. In the top left corner of the photo is a Euphorbia flanaganii. The leaves are from a toyon.

This Crassula ovata 'Gollum' was part of an assorted succulent pack planted in an inconspicuous partly sunny location 6 years ago. It’s thrived through the extremes of unusually heavy winter rains and last summer’s persistent heat waves. Today it’s about 2.5 ft tall and wide. 🌱 #succulents
Pictured is a Crassula ovata 'Gollum' (Gollum Jade), rising above a variety of smaller succulents (mostly Kalanchoe). In the background are the fronds of an Australian Tree Fern and the blurry trunk of a Live Oak. This Crassula features grey bark marked by dark rings and leaves that are tubular with cup-like tips. This plant is about 2.5 feet high and wide.

Abundant diversity bordering this path - succulents to tree ferns / Japanese maples / Palms and Live Oaks. After 25 years of experimenting finally settled on a selection of plants that offer seasonal interest and minimal regular maintenance. (5/5/2025)
🌱 #succulents
Patio Path leading to backyard garden. The pathway is composed of Flagstone with railroad tie steps and is bordered by field stone. Most prominent on the left side of the path are Agave attenuata 'Ray of Light’, several fine leaved red Japanese maples / frond of an Australian Tree Fern poking out above the top left maple. On the right side of the path are succulents with a variety of Aloes, Agaves and even a Gastoria maculata which is somewhat rare in our area. Toward the top of the steps are Queen and Phoenix roebelenii (dwarf date) Palms. In the background are live oak and a Crepe myrtle.

The ‘pump shed garden’ conceived and planted winter-spring ’25 and designed around 3 yucca rostradas, a Bismarckia palm, an Agave 'Hakuro Shiro Fukurin’ , an Agave vilmoriniana and a Mangave "Kaleidoscope". To be renamed the ‘garden of relief’ when we are rid of the shambolic regime.

Kalanchoe fedtschenkoi (lavender leaf plant, floriferous, bryophyllum) - A robust and easily grown succulent in zone 9-11 gardens, nice blooms and the leaves turn lavender when the plant is stressed. It’s proliferated throughout our garden but it’s not a pest, easily controlled. 🌱 #succulents
This photo taken 03/2025 is of a blooming Kalanchoe fedtschenko growing over a boulder in our backyard garden. The flowers are pink to red and the leaves are light green to lavender.

March 2025. I’ve been removing the Woodsorrel (Oxalis) and doing light cleanup in this garden. The multi-stalked, magnificent (almost full) bloomer is Aloe Taurus. Also noteworthy are the Agaves Blue Glow and Blue Flame which are great companions. Other plants mentioned in the Alt Txt 🌱 #succulents
This garden is a mounded Noyo cobble rock garden. The mound is a mix of amended loam and succulent mix. The garden is encircled by oaks, a naval orange, pittosporum, Photinia, paths and other gardens. It was originally planted from 5 gallon plants obtained from Seaside Growers Nursery - about 475 miles south of our home in Sonoma County. The garden is full sun mid summer but otherwise lightly shaded with dappled light in winter.

Aloe glauca (Blue Aloe), mid summer 2023. It prefers full sun (part-sun in warmer valley locations). This aloe is somewhat stressed beneath a Live Oak which is periodically messy with leaf drops (early spring) and sap (late summer). It receives dappled summer sun. Very hardy. 🌱 #succulents
This photo is of an Aloe glauca against a background of field stone and Noya cobbles. The leaves are green to dark grey-blue with orange teeth along the leaf margin bed of field.

Aloe brevifolia growing amidst our regular winter clover. The brevifolia is zone 8 hardy. This plant with it's clumping offsets is about 8” wide and 6” tall. The garden location is part sun so the Aloe’s green-blue color is year round. In sunny locations it will take on a reddish tint. 🌱 #succulents
This photo was taken in Jan '25. The Aloe brevifolia (centered) is green to blue in color and has spikes around the leaves. Surrounding the plant is our winter crop of clover.

An Aloe striata situated along the top of a rock wall. Hardy into the mid 20s. This striata receives a dash of late afternoon so the plant’s appearance is slightly less robust than others in sunnier garden spots. Even so, it has nice color and is staying put. 🌱 #succulents
Aloe Striata atop a rock wall. The plant has green to slightly blue leaves (maybe due to insufficient sun exposure) with a red stripe that runs along the leaf margin. It is about 2 feet wide and a foot tall.

May of 2016 Oscularia deltoides flanked by a Aeonium arboreum(?) both potted. Regarding the name 'Oscularia' … my high school Latin was of no help. I was less than attentive as a student (apologies to Mrs Augustitus, my Latin teacher). A lesson on the naming in the Alt Image text. 🌱 #succulents
A Oscularia deltoides (ice plant) covered by pink flowers. Next to it is an Aeonium with about an 18" wide rosette. As for the Latin - from San Marcos Growers "The name Oscularia is Latin from the word 'osculum' meaning "little mouth" with 'oscularia' meaning "a collection of little mouths" in reference to the way the leaves appear as open mouths (teeth and all). The specific epithet comes from the Latin word for triangular in reference to the 3 angled leaves."

This Agave geminiflora has won the day. Years ago it was 'temporarily' placed along a walkway, never removed from its 3 gallon growers pot. Kept thinking it needed to be properly planted … somewhere. Meanwhile, it made some friends and took root. 🌱 #succulents
This is an Agave geminiflora about 2'X2' growing along a garden path. It's leaves are dark green, linear, somewhat flexible. Adjacent to the Agave are a variety of green to purple leaved succulents and landscape rocks.

Agave lophantha 'Quadricolor' brightening up a patch of green Senecio. In our location it's been a vigorous grower generating many offsets. After a few years in-ground it's ~18” tall X 24” wide . At our zone 9b location it looks best with AM sun, PM shade. 🌱 #succulents

Up close, Aeonium ‘Sunburst’ - Grows well in our Zone 9b wet winter garden, really brightens things up. In spring mature plants produce a long lasting, impressive bloom (monocarpic). Dormant in the summer when I'm light on the irrigation, might benefit from consistent weekly water. 🌱 #succulents
This is an Aeonium 'Sunburst' (Copper Pinwheel) rosette from above. It is about 8 inches wide and a foot tall. The leaf margins are lined by a thin copper stripe, the leaf color is dominated by yellow with a trip of green up the middle. In our garden we grow it in sun to part shade, it's said to be hardy to 28 degrees F.
