Ruellia

Native to the tropical and subtropical regions of the Americas. Five species of Ruellia occur in nature. This is a fast-growing houseplant that can be grown in hanging baskets or pots.

Ruellia Devo - Ruellia devosiana - a herbaceous perennial about 40 cm high. Stem with grayish pubescence, leaves up to 7 cm long, elliptic in shape, velvety, dark green on the upper side, lighter along the veins, underside purple. Flowers up to 2 cm in diameter, solitary, axillary. The corolla limb pale lilac or white.

Ruellia Portellae - Ruellia portellae - a herbaceous perennial about 50-60 cm high. Stem with grayish pubescence, leaves up to 8 cm long, oblong in shape, velvety, dark green on the upper side, lighter along the veins, underside purple. Flowers up to 2.5 cm in diameter, solitary, axillary. The corolla limb bright pink.



Temperature: In summer preferably not above 22°C. Minimum in winter 14°C.

Light: Ruellia is light-loving but in spring and summer requires shading from the midday sun. To prolong flowering, in autumn additional lighting is used so that the day length is at least eight to nine hours.

Watering: Abundant in summer; the soil should be kept slightly moist at all times. In winter moderate, but the soil should not dry out completely.

Fertilizer: From April to August Ruellia is fed with liquid fertilizer for indoor ornamental flowering plants every two weeks.
