Although most often grown as annuals, nasturtiums are, botanically, herbaceous perennials; that is, they die to the ground in fall and grow again the next spring. In frost-free areas such as coastal California, they grow like weeds, with 6-inch diameter leaves atop 20-foot-long stems sprawling year-round.Do nasturtiums need to be deadheaded?Dry leaves and wilted blooms signal the need to clean bushy nasturtiums. Deadhead blossoms and pinch flower stalks back to a cluster of leaf stems whenever you find wilted or dead flowers. Regular deadheading can extend the blooming season.
