What's this tree?

[MattyB]

A friend of mine posted this on facebook, wondering what it was. I thought it looked like a Tabebuia. Eric, Ken, Jerry, any other tree experts have an idea?

My friend wants to plant one in Denver, CO. Is the pink one hardier to cold (assuming it is a Tabebuia)

Definitely a Tabebuia, T. chrysotricha. The pink T. impetiginosa is the other more commonly seen species here in California. The genus name has been changed again, they're no longer considered Tabebuia. Both can take some freezes and do well here in the SF bay area, there are some large blooming trees of each out in Walnut Creek at the Ruth Bancroft Garden, where it is a USDA zone 9a, and almost each winter will drop into the low to mid 20'sF. No way any Tabebuia would survive outdoors year round in Denver. They bloom best up here with locations with hotter summers, but I've got some T. chrysotricha planted right by the bay in Alameda which bloom.

I agree, T. chrysotricha, now known as Handroanthus chrysotrichus.

thanks guys

Pink and yellow grow really well in SoCal. I prefer the yellow. The yellow flower are bigger and stands out more. My yellow tree produces lots of volunteers too.

Could this be the same species as Matty's? Been meaning to post these photos figure might as well piggy back on this one.

That is a completely different tree. It is Guerilleana moosiflora.

The reference books all seem to say that both these species can repeat bloom in southern California as the get larger, blooming again in the fall on occasion. Is this the case in your area? I'd be hardpressed to say which is more beautiful, I've seen some pinks that were phenomenal in bloom, and the glossier and denser foliage on T. impetiginosa gives the tree a different look. We're still months away from blooming here in Berkeley, usually more like late March/April around here.

I doubt that it can bloom more than once a year. Mine have bloomed three years and I don't see the second one. The Safari Park has many older trees and they bloom only once per pear. Yes, the pink variety has more flowers but they're slightly smaller(flowers). There are about half a dozen at nearby Palomar College and every branches are just full of pink flowers every year. They are indeed very nice. The better looking is just my opinion

Jerry - are you sure? I can't locate that botanical name?

Handroanthus genus appears to be an annual bloomer in So. Florida from what I have observed.

[Eric in Orlando]

Usually they are just annual bloomers. But sometimes Handroanthus umbellatus (Tabebuia umbellata) will have a 2nd bloom. We have a few at Leu Gardens that will flower heavy in March like they normally do then late April/early May a 2nd lighter bloom.

There is also H. heptaphyllus (T. heptaphylla). It was once lumped into T. impetiginosa but is now a valid species again. It is a purple flowering species and flowers heaviest in fall, Sept./Oct. but then usually again lightly in spring. We have one older tree that does this. But a seedling grown off this tree has flowered almost every month for the past 2 years. Heavy in fall, a 2nd lighter bloom in spring then it has had sporadic flowers in between. But has flowered every month for the past 2 years.

Eric - Out of curiosity, is it possible to air layer the Handroanthus umbellatus with the unusual continuing flowering characteristic?

Blooming has increased. Updated photo taken last night.

a talk about tabebuia? Where is Peter?
