An interesting species differing from others in entire leaf margins, obtuse to emarginate leaf apex; shrub with leaves clustered at tips of short branches, oblong-obovate, 3-5 cm long, rounded to emarginate at apex, margin entire, base tepering to short petiole, pubescent beneath; flowers white, 6-9 mm across, in small clusters; calyx slightly pubescent with triangular lobes; fruit depressed globose, red.
Closely similar P. coccinea differes in elliptic leaves, crenate-serrate margins and orange red fruits.
Seen in Fremont in Sept 2014.

Climber full of red berries seen in Fremont on 28th Sept,14.
I hope it is a climber, not a tree.
Id please.

It seems to be a shrub and not a climber as I initially thought.

Another Pyracantha with lighter Orange berries seen in Fremont.
Pyracantha koidzumii?
efi page on Pyracantha koidzumii (Cultivated- USA) For me also Pyracantha koicampus.dzumii ‘Santa Cruz’ syn. Cotoneaster koidzumii Hayata. I have seen this in many places of California and University of Berkely .
Thanks for the id.
I hope you meant to say Pyracantha koidzumii ‘Santa Cruz’.
A typo error…..you meant to say University of Berkeley campus ?
What … was implying was University of California, Berkeley. or UC Berkeley …
and yes the plantings at the campus would be many many varieties. And … would remember these spectacular plants. .
And Cotoneaster plants are a popular species for the winter birds’ food Thanks for the correction. I meant Berkely campus, UC only. I enjoyed visiting the campus as well as the Botanical garden. I have photographed several plants. Interesting thing is: I was about to step on a snake which was crossing (criss-crossing) the narrow road and I was dragged by my son who noticed the reptile !
what a scare because some snakes in the dry california areas can be rattlers too
so its always nice to stay away good quick reaction on your son’s part, good for you. == May be you’ll show us some of your pics from UC Berkeley ? Rosaceae Fortnight: Pyracantha coccinea from California-GSSEP69/69 : 1 post by 1 author. Attachments (2)

A relook at this post was mandated today by a post on a WhatsApp Group, which may need checking our plants in cultivation. Two species which I have from California, initially mixed up but now clearly distinguished. The fruits in both turn from green to yellow, orange and finally nearly red as they fully matured. They are differentiated as:
Pyracantha coccinea: leaves narrowly elliptical, finely crenate-serrate along margin, tip acute, inflorescence pubescent.
P. koidzumii: leaves obovate-oblong, margin entire, apex obtuse, nearly rounded to emarginate, inflorescence glabrous.
This plant is clearly P. koidzumii.
I will upload real P. coccinea separately.
