Also known as bower plant, pink bower vine (Pandorea jasminoides Rosea) is a fast-growing vine that reaches heights of 20 to 30 feet at maturity. The vine adds color to the landscape all summer, displaying soft pink, bell-shaped blooms with dark pink throats.. Water bower vine regularly during the first year. Water deeply to saturate the entire root zone. Avoid shallow irrigation, which creates shallow roots rather than deep, strong roots. Allow the top of the soil to dry between each watering.
