Ti Plant Cordyline 'Glauca'An eye catcher! Maybe it's because of the shape of the leaves, or the deep green colour We can't take our eyes off the Good luck plant (Cordyline fruticosa) 'Glauca'! This tropical plant needs very high humidity. That is why we spray the leaves at least once per week. This prevents the leaf edges from drying out. Always keep the potting soil moist, without letting the plant stand in water. The plant does like light, but not strong, midday sunshine.
