Do you know which Tecoma it is. The leaves are really distinctive and nice. I do not know how variable the T. stans is.

Yep! Some trees are really strong.
They just removed a 25-30 year old Ficus close to our residence, which grew almost as large as a house. Same problem, roots uplifting the road, (and probably there were some major complaints by the flat inhabitants 5-10m away from the tree.)
I spent a couple of minutes on the net but got no Tecoma with those leaves. I suspect a hybrid, but not yet game over.
I know for sure that there exists the lanky, droopy-leaf type like yours and mine, and also a more compact / robust variety - not sure if the latter is actually T. stans but at first glance very similar.
One the other hand one might consider the fact the there are a number of Tecoma species named for the shape of the leaves, thus giving a clue that the shape of the eaf is somehow important. (Wikipedia)
I really like you link and I am taking part of the site and paste the text here for educational purposes:
Source: FLoridata.comCommon yellow elder (Tecoma stans var. stans) is a Central and South American tree that grows to 25 ft (7.6 m). It has bright yellow flowers and dense, lushly green foliage that is evergreen in tropical climates, but deciduous in chillier places. It is reliably hardy only down to 28ºF (-2.2ºC), though the roots may survive temperatures into the low twenties. Arizona yellow bells (T. stans var. angustata), which comes from the Chihuahuan Desert in Texas and New Mexico, is a 10 ft (3.1 m) deciduous shrub, which is hardy to 10ºF (-12.2ºC) and can be grown as a herbaceous perennial to Zone 7. It has relatively small flowers and lacy foliage made up of narrow, deeply toothed leaves. 'Gold Star Esperanza' is intermediate between var. angustata and var. stans. It grows to 3-4 ft (0.9-1.2 m) as an annual and is marketed as a Zone 9 patio tub plant. Whereas other yellow elder varieties do not bloom until they are medium-sized shrubs, 'Gold Star Esperanza' begins flowering even as a liner and is therefore more readily marketable in the nursery trade. T. alata is a very similar Argentine native that is root-hardy to at least 6ºF (-14.4º C). It looks like T. stans var. angustata, but has orange flowers. It is sold under the name 'Orange Jubilee'. 'Burnt Out' is a hybrid of T. alata and T. stans var. stans. It has burnt orange flowers and can be grown as a perennial in Zone 7. 'Orange Bells' (Tecoma x smithii) is a cross of T. arequipensis and T. stans. T. chrysantha has larger flower clusters and more dramatically serrated leaf margins. T. gaudichaudii (a.k.a. T. castanifolia), which has naturalized in the Miami area and the Dry Tortugas, has similar flowers but simple leaves.

Would be nice to hear the German experts opinion.
