I saw a small/medium tree, with a growth habit very similar to a Poinsettia, (E. pulcherrina) also the size, etc - in fact from a distance they are so similar in shape (long stems, etc) that one could think it was a different type of P. - but which most certainly is not, it is not a Euphorbia, no milky sap, and true flowers.
The flowers in this specimen are pinkish, double, and about 8cm diameter. The leaves are slightly downy, 8-15 cm, angular/rounded in shape.
The tree is deciduous, currently bare except for dried flower heads, (about 3-5 per stem tip) and located in Zabbar, in a garden.
A pic of the plant will be informative for the members - only if you have time.
In the meantime I leave a link of images of Hibiscus mutabilis (never seen it.)
