In 1994, when I first saw the tree yucca, Yucca filifera, growing in the mountains of Northern Mexico, it immediately went on my plant lust list. My first plants, acquired under the old name, Yucca australis, all met with a demise as untimely as The Late Show with Stephen Colbert. I thought our garden spots were dry enough for this denizen of the bone dry mountains, but our 46″ annual rainfall proved too much.
It wasn’t until our tenth attempt, in 2006, that we sited one in a dryer space near a row of agressive-rooted dawn redwoods. In 2017, we transplanted our surviving plant to our newly built crevice garden, where it has continued to thrive in near perfect drainage. Our 19 year old specimen has reached 19′ in height. Skirting our yucca like a sequined see-thru dress, is JC Raulston’s introduction, Campsis grandiflora ‘Morning Calm’.

Tony, please post on your Yucca treculeana sometime. Thank you!
Campsis ‘Morning Calm’ was named by the late Darrel Apps and introduced by me. The plant in the photo above is not ‘Morning Calm’
Thanks for the correction. Our plant came from the JC Raulston Arboretum as such, but looks more like a C. radicans x grandiflora hybrid. I remember that JC Raulston grew this in 1991 prior to it being named. Any chance you remember where Darrell collected it, and when it was named and introduced. Many thanks.
