The New Guinea plant is vigorous, has dark green lanceolate leaves and emits bright, medium-sized flowers in shades ranging from white to pink to red.

More moderate irrigation for plants grown indoors. Harmful in the same way is drought, so always fresh soil.

The multiplication of these plants is very easy, by sowing or by cuttings, indistinctly. The only downside to cutting is that modern cultivars propagated in this way will hardly retain flower characteristics over time. From this point of view, the seed certainly gives more guarantees, that said if you want to propagate your new guinea plant you only have to take the cuttings in autumn or spring or in autumn or at the end of winter if you have opted for the seed, the ideal substrate is composed of half peat and half peat. when night temperatures no longer fall below 15°C, be careful because the cold kills New Guinea, as for the soil, it must be rich in organic matter, light and fresh.
