Keep an Eye Out for Summer Limb Drop

As the afternoons here get hotter and more humid it is the well irrigated trees that can become a threat. Summer limb drop affects trees like the Floss silk tree, The Italian stone pine, and other susceptible varieties. Here is a news interview I did on the subject several years ago after some children were injured by a falling pine tree :

What's Blooming at the L.A. Arboretum and Botanic Garden, October 14th 2016

Ceiba (form. Chorisia) speciosa

Floss-silk trees as they are commonly known can be highly variable as to when they start blooming, but since I've been here (1998) they have always been consistently blooming when the World Series comes around.  In the photo below you will see at least two of the four varieties that the Arboretum introduced around the early 1980's; September Splendor and Arcadia.

Ceiba speciosa 'Arcadia'

Tabebuia avellanedae var. paulensis 

Identified here as Tabebuia impetiginosa 'Paulensis', this seems a miniature version of Handroanthus impetiginosa. It usually blooms several months earlier than the latter and its blooms can be far more dense. For more info on these beautiful trees see Matt Ritter's article in Pacific Horticulture.

This tough, salt resistant native to the Canary Islands and the west Atlantic coast of southern Europe and northern Africa blooms Spring and Fall and in between.
