Bignoniaceae. Could be any of a number of them; even the flowers of Paulownia tomentosa are similar. Without seeing leaves I couldn't say more.
Podranea ricasoliana? (via Plantzafrica, the South African National Biodiversity Institute's plant information website)
Hi, I'm with Daniel = Podranea ricasoliana (Bignoniaceae) = "Pink Trumpet Vine". Commonly grown here in southern Portugal (just across the water from Morocco). A vigorous climber that flowers for quite a long period - perhaps 6 months. Grows best in full sun. Tolerant of wind and some salt. Needs little water but grows better with some irrigation in summer. A great plant ! Podranea, the genus name has no scientific meaning - it is just an anagram of the related Pandorea !! Ciao Brian
