No bloom in cool water
As a tropical it will not flower until water is warm, above about 20°C. Delay planting out until early summer or grow it in heated water under glass.
Frost damage and winter loss
Frost-tender; the crown dies if frozen. Lift the tuber before the first frost and overwinter it warm and just moist, or keep the plant in a heated conservatory pool.
Pests on lush foliage
Vigorous tropical leaves draw aphids and china-mark moth caterpillars. Spray aphids off with water and remove mined or rolled leaves by hand rather than spraying chemicals.
Weak flower colour or quantity
Shade, cool water or under-feeding dulls the violet-blue and cuts bloom count. Maximise sun and warmth and feed every few weeks through summer.
