DESCRIPTION:

Both parents of this hybrid have very deep scarlet flowers. P. quadrifaria differs in its light orange hue, while P. vitifolia tends towards vermilion red.

The flowers of P. x piresae could not differ too much from those of its parents: the result is a bright red with, in my opinion, perfect luminosity.

The two parents also have flowers of different shapes.

Those of P. vitifolia are very large, have slender petals and sepals with a lanceolate shape; on the contrary, those of P. quadrifaria are smaller, at least 8-9 cm in diameter, and its petals and sepals are linear, with their apices folded slightly inwards.

The hybrid from the two species has essentially intermediate characteristics. The flower is larger than that of P. quadrifaria and has the advantage of not completely retroflecting within a few hours, as is the case in P. vitifolia.

The result is a plant that elegantly produces bright flowers in a lively, brilliant red. Not only that, but this easy-to-grow hybrid offers generous and continuous flowering, which, contrary to P. quadrifaria, also occurs in smaller specimens and in recently rooted cuttings.

Its leaves have a shape similar to those of the mother, since they are whole and not trilobate; however, they have a similar texture to those of P. vitifolia.

P. x piresae is a pot plant, to be treated as a houseplant with the needs and charm typical of exotic and tropical plants. Indeed, it is not very hardy and in winter, it should not be kept at temperatures below 10 °C.

Propagation is done with cuttings.
