About Vanda 'Robert's Delight'

Vanda 'Robert's Delight' · also called Robert's Delight Vanda · tropical

Vanda 'Robert's Delight' is a large, sun-loving hybrid famous for its big, flat, tessellated flowers in shades of blue-purple, red, and pink. A monopodial orchid with thick aerial roots, it is usually grown bare-rooted in slatted baskets. It demands very bright light, high humidity, warmth, and daily watering to flower repeatedly through the year.

Mature size: Stem and foliage 45-90 cm tall; flower spikes carry 6-12 blooms up to 10-12 cm across

Watch for — No flowers despite healthy growth: Almost always too little light. Vandas need very high light — move to your sunniest spot or add strong grow lights to trigger blooming.

Indoor size vs how big it gets in the wild

In the ground with no restriction it is a completely different plant — flower spikes carry 6-12 blooms up to 10-12 cm across — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It builds steadily in both height and spread to a medium, manageable size, filling a pot and a corner over a few years.

Its feeding profile backs this up: heavy feeders in active growth — apply a balanced orchid fertiliser at quarter to half strength with most waterings during warm months (the classic weakly, weekly approach), flushing with plain water periodically. reduce feeding in cooler, lower-light spells.
