Tolumnia Jairak Firm 'Big Bang' lives up to its name with an explosion of color! The bright yellow flowers with big red flares make these little flowers a great show-off piece. Plants are flowering size in 1.5" net pots. We grow our Tolumnia in empty clay pots or net pots being watered as frequently as our Cattleyas. We suggest growing them on the dry side, but you should adjust your care based on your conditions.
