Megawatt™ Rose Bronze Leaf Begonia

Megawatt™ Rose Bronze Leaf is a vigorous interspecific begonia selected for its rose-colored flowers held above bronze-toned foliage. Its upright, mounded growth and substantial size create a long season of color in beds, large containers, baskets, and border plantings, where it can be used as a bold seasonal accent. ## Flowering and placement The [PanAmerican Seed product profile](https://www.panamseed.com/products/009207585004677/begonia-megawatt-rose-bronze-leaf/) confirms the exact selection and PAS1438018 code, with a 20–28 inch height, 16–24 inch width, mounded upright habit, and flowering from spring through autumn. It recommends the series for landscapes, baskets, containers, and borders, and lists sun or shade exposure. The [RHS begonia trial report](https://www.rhs.org.uk/plants/trials-awards/plant-trial-results/begonia) also names the exact PAS1438018 selection; its 2025 trial notes continued flowers into October in the UK. ## Growing conditions Use fertile, moisture-retentive but well-drained soil and shelter from cold; begonias are tender and should be planted outdoors after frost danger has passed. The [RHS outdoor begonia guide](https://www.rhs.org.uk/plants/begonias/outdoors) recommends sun or partial shade and regular watering during dry periods while avoiding wet foliage. This cultivar is grown as a warm-season annual in cold-winter climates. ## Maintenance Keep the root zone evenly moist during active growth without leaving pots waterlogged. Remove spent or damaged flowers and leaves as needed to maintain a clean display, and protect or replace plants before frost.
