1. Sweet Pea lathyrus odoratus must rank near the very top of any list of favourite annual flowers. they will grow 6-10 feet tall and if the flowers are picked regularly they will give endless scent and pleasure.
2. Morning Glory Ipomea purpurea or convolvulus major has purple funnel-shaped flowers from summer until the frosts. Or tricolour ‘Heavenly Blue’ is a great variety
3. Cathedral Bells Cobaea scandens may be half hardy perennial but it is best grown an an annual each spring for the purple veklvety bell shaped flowers.

9. Lophospermum scandens also looks like a snapdragon with nlarger more colourful flowers.
