When grown in small containers, its tubers need to be de-eyed before planting, and they take 2 to 5 more days to sprout than those of other cultivars such as ‘Freida Hemple’ and ‘Postman Joyner’.

Royal Flush was evaluated for tuber production and plant performance at the Florida Gulf Coast Research and Education Center. Results showed that it was significantly more productive than other commercial cultivars in 2005.

Still, in 2006, it was comparable to different cultivars in terms of tuber weight, number of marketable tubers, and production index. Its size distribution of tubers was also similar in 2005 and 2006, with approximately 60% of the tubers graded as No. 1 and Jumbo and approximately 20% in the Mammoth size. In a greenhouse evaluation, Royal FlushTM ‘UF-18-49’ was found suitable for container forcing, with growth parameters compared to other cultivars.

Caladium Royal Flush care

Caladium Royal Flush is a beautiful plant that requires specific care to thrive. It can be planted in either sunny or shady landscapes and in large containers, but it prefers partial shade and moist, well-drained soil. The soil should be kept consistently moist, but not waterlogged, to avoid root rot.

When planting Royal Flush, it is important to ensure that the tubers are planted facing upwards and about 2 inches deep in the soil. The plant should be fertilized regularly with a balanced fertilizer to promote healthy growth and vibrant foliage.

To maintain the plant’s appearance, it is recommended to remove any yellow or damaged leaves as they appear. Deadheading can also encourage new growth and prevent the plant from going to seed. In addition, Royal Flush can be propagated by dividing the tubers during the dormant season, which is usually in the winter months.

Suitability for container forcing

Caladium Royal Flush is a popular ornamental plant that is often used for container forcing. The plant has large leaves with a red center and is a vigorous and tall plant, making it a great choice for container growing. The Royal Flush cultivar is particularly well-suited for container forcing due to its adaptability to different light conditions, including both sunny and shady environments.

In terms of soil requirements, the Royal Flush caladium prefers well-draining soil with good aeration and high organic matter content. It is important to choose a container that is at least 8-10 inches in diameter and has adequate drainage holes to prevent waterlogging. Caladiums also require frequent watering, especially during periods of hot weather, to prevent the soil from drying out.

Fertilization is also important for container-grown caladiums, with regular applications of a balanced, water-soluble fertilizer recommended every 2-3 weeks during the growing season. Royal Flush caladiums grown in containers may also benefit from occasional pruning to maintain a compact shape and to remove any damaged or yellowing leaves.

Overall, the Royal Flush caladium is a suitable choice for container forcing, offering beautiful foliage and adaptability to a range of growing conditions. With proper care and attention to soil, water, and fertilizer requirements, container-grown Royal Flush caladiums can provide a stunning addition to any indoor or outdoor space.
