This plant is in our garden in Santa Monica, CA, about a mile from the coast At some point we'll need to prune the lower limbs (for visibility - safety)
Does anyone know the best time of year to do this
The flowers are spectacular this year---- we're having a lengthy drought with humidity----

Nice plants, very pretty leaves, but painfully slow growing, at least here in Florida.

I planted the stenocarpus sinuatus from a five gallon pot about 5 years ago.

No damage at 24 degrees. It is getting ready to bloom for the first time. I noticed the flower wheel buds throughout the tree today. I live in Newark, Ca. which is between Oakland and San Jose.

Just discovered this tree last week at local botanical garden when it was in full flower. Creepy flowers- look like neon tarantulas poised and ready to drop on your head as you walk under them. Pretty incredible flowers!!
