B. ‘Mini City series’

The Mini City Series is a marketing collection, supposedly of smaller growing Rex Begonias. In 2015 there were 4 cultivars in the series: Mini Miami Storm, Mini Portland Picotee, Mini Tuscaloosa, and Mini Boston.

• Classification: Cultivar
• Plant Type: Rex Cultorum
• Origin: USA
• Originator: Booman Floral

Growing Conditions: Light: Bright, indirect light year-round. Because they are not aggressive bloomers, they can tolerate less light than other begonias and will thrive under fluorescent lights. Water: Rex begonias like even water, but hate being overwatered, and they thrive on humidity, but don't like direct misting, which encourages powdery mildew. Temperature: Average to warm (and humid). They cannot tolerate freezing, and some types of Rex begonias go into a dormant period during the fall. Soil: Airy, light, fast-draining soil. Fertilizer: Use liquid fertilizer weekly at quarter strength or biweekly at half strength. Propagation: The vast majority of begonias offered in the trade are hybrids and thus cannot be accurately propagated from seed. Rhizomatous begonias can be easily propagated by rhizome division during repotting, while almost all begonia species will readily sprout from leaf-tip cuttings. A rooting hormone can help the cuttings sprout. Rex begonias can also be propagated by pinning a leaf bright shade
