Maybe mexican white oak or montezuma cypress.

Rather cliche for the South, but there are many crapemyrtles, especially the largest ones such as Lagerstroemia faureri (really pretty orange bark iwth white flowers, 20-30' when mature and rounded canopy) or the 'Natchez' cultivar of Lagerstroemia indica (or a hybrid of) that is also white flowering and gets about 25-30 tall and 25' wide with a oval and spreading canopy when mature, also with pretty bark that is cinnamon in color.

Crapes are usually always disease free and NEVER hatrack a crapemyrtle tree--there are clueless landscapers all over the South that still do this.

SOrry, I wish I would have posted this link in my last posting, but here is a link to a database showing lots of different crapemyrtles. Click on the diffferent names or ones with photos (and make sure to click on the green "details" tabs to learn of mature tree heights).

'Dallas Red' has a pretty photo of what a large crapemyrtle looks like in a suburban yard!

Here is a link that might be useful: listings of crapemyrtle varieties

You don't state where you are located. You need to contact your county extension office and speak to a Master Gardener. They should have information on which plants do best in their particular county.

Here is the NUECES COUNTY LANDSCAPE PLANT LIST. It has recommendations for all plants and trees for the CC area.
