Description of Nymphaea 'Mangkala Ubol'

Nymphaea 'Mangkala Ubol' is a hardy water lily bred for large, warm-toned flowers and a strong garden-pond presence. It grows from a rhizome and forms a broad raft of pads, then produces showy blooms through summer. Many listings describe it as peach with a pink exterior and warmer orange tones inside. The cultivar name Mangkala Ubol is the term people use when buying it, and it suits ponds where you want a softer, two-tone flower rather than a flat yellow or solid pink.

Appearance

Mangkala Ubol makes rounded floating pads and can build a substantial surface patch. Several UK suppliers list leaf spread around 90–120 cm, and some allow more in strong growth, so it is best treated as a medium to large lily. The flowers are described as large and double, with a peachy to creamy yellow base and warmer pink or orange tones, depending on the stage of the bloom and the light. Multiple sources mention fragrance, which adds to the appeal if you view the pond close up. The overall look is warm and slightly antique rather than bright and sharp.

Care Guide

Give it full sun and still water. Plant in a wide basket with heavy loam based compost and cap with washed gravel. Many suppliers recommend a planting depth around 30–60 cm of water over the crown. Start on the shallow end in spring and lower gradually as the plant establishes. Feed with aquatic fertiliser tablets during the growing season, especially if you want repeat blooming from a large-flowered cultivar. Remove old leaves and spent flowers so they do not sink and add to pond muck. It is hardy, so leave it below the ice line in winter.

Suitability for Garden Ponds

Mangkala Ubol suits medium to large ponds where it can make a generous pad raft without taking over the entire surface. The leaf cover provides shade for fish and can help reduce algae by limiting light. The two-tone flowers look best when you can see them from above, so position the basket where you have a clear view from the edge. In smaller ponds, you can keep it contained in a basket, but be ready to divide once it fills the pot so you keep open water visible. Keep a patch of open water next to Mangkala Ubol so you can enjoy the flowers properly from the edge. A wide basket helps Mangkala Ubol root evenly and usually improves the flower count.
