Rosemond Coles

Canna Rosemond Coles bulbs, also known as rhizomes, are easy to plant and can provide a stunning display of large, tropical-like leaves and vibrant flowers.

• Begin by selecting well-draining, fertile soil in a location that receives full sun, as these plants thrive in warm and sunny conditions.
• Plant the bulbs in spring after the last frost, placing them horizontally in the soil about 4-6 inches deep and 18-24 inches apart.
• Water the newly planted bulbs thoroughly and consistently throughout the growing season, ensuring the soil remains moist but not waterlogged.
• As the plants grow, provide a balanced, slow-release fertilizer to promote healthy growth and flowering.

Canna Rosemond Coles bulbs will reward your efforts with a spectacular garden showpiece, attracting hummingbirds and butterflies with their vivid colors.

Canna Rosemond Coles bulbs typically bloom from mid-summer to the first frost in fall, with a flowering period that lasts around 8-12 weeks. These plants are renowned for their stunning, large, and vibrant flowers that come in shades of red, orange, yellow, and pink.

The exact timing of their blooming period may vary depending on local climate conditions, but they generally perform best in warm, sunny environments. To encourage an extended blooming period, deadhead the spent flowers regularly, and provide consistent moisture and nutrients throughout the growing season. With proper care, your Canna Rosemond Coles bulbs will produce a breathtaking display of tropical color in your garden.

Canna Rosemond Coles bulbs are not frost-hardy in USDA hardiness zones 6 and below, as they are native to tropical and subtropical regions and require warm temperatures to thrive. In areas where temperatures fall below freezing during winter, it is essential to lift and store the bulbs to protect them from damage.

After the first frost, cut back the foliage to around 4-6 inches, carefully dig up the bulbs, and gently remove any excess soil. Store the bulbs in a cool, dry location with good air circulation, such as in a cardboard box filled with peat moss, perlite, or vermiculite. Make sure the bulbs do not touch each other to prevent rot. Replant the bulbs in spring after the risk of frost has passed, and enjoy another season of spectacular Canna Rosemond Coles blooms.

In USDA hardiness zones 7 and up, you can leave Rosemond Coles canna in the ground and just add an extra layer of mulch during the colder months.

Propagating Canna Rosemond Coles bulbs is a simple and effective way to increase your stock of these stunning plants. The best time to propagate is during the dormant period, typically in late fall or early winter when you lift the bulbs for storage. Carefully examine the rhizomes and look for healthy, well-developed "eyes" or buds, similar to those on a potato.

Use a clean, sharp knife to divide the rhizomes, ensuring that each section has at least one eye. Allow the cut surfaces to dry and heal for a day or two before planting or storing them for the winter. When spring arrives, plant the divided rhizomes in well-draining soil, following the same planting guidelines as for mature Canna Rosemond Coles bulbs.
