Climbing plant with pastel coloured flowers (5,3)
I believe the answer is:
sweet pea
(Other definitions for sweet pea that I've seen before include "Eat, weeps and gets climbing flowers" , "Pew tease (anag) - flower" , "Climbing garden plant - saw tepee (anag)" , "Fragrant bloom" , "Peseta we paid for climbing garden flower" .)
