Rocket White Snapdragon

Rocket White is an upright snapdragon with white flower spikes for spring and autumn displays. The [PanAmerican Seed cultivar page](https://www.panamseed.com/Products/057701271005863/snapdragon-rocket-white/) lists plants 30–36 inches tall and 16–18 inches wide, with flowering in early spring, spring, and autumn; the series is described as vigorous and heat tolerant for garden beds and cutting. ## Garden Use Snapdragons bring upright flower spikes and seasonal color to grouped beds and borders. Depending on cultivar, they can also be used in containers, edging, or cut-flower arrangements. The University of Florida describes snapdragons as annual bedding plants in common landscape use, with some plants acting as short-lived perennials in warmer zones. [UF/IFAS](https://ask.ifas.ufl.edu/publication/FP044) gives species-level context; choose placement according to the documented mature size of this selection. ## Site and Care Grow in sun and moist, well-drained soil. Snapdragons prefer cooler growing conditions and have low drought tolerance, so provide water during dry periods, especially while new plants establish. The University of Florida recommends good drainage and notes that drought tolerance is low; seasonal timing varies with climate. [Illinois Extension](https://extension.illinois.edu/flowers/snapdragon) describes snapdragons as cool-season flowers and supports spring or fall use in many northern gardens. ## Maintenance Remove faded flower spikes to keep plants tidy and encourage rebloom when conditions are suitable. Tall varieties may need staking in exposed sites; compact selections usually need less support. Avoid treating snapdragons as drought tolerant. [Illinois Extension](https://extension.illinois.edu/flowers/snapdragon) recommends deadheading and notes that tall cultivars may require support.
