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.

Pallenis maritima the 'Gold Coin' plant

Pallenis maritima the 'Gold Coin' plant

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.
