Carnivorous plant to 30 °C to thrive. Carnivorous plants require appropriate nutrient-poor soil. Most appreciate a 3:1 mixture of "Sphagnum" peat to sharp horticultural sand (coir is an acceptable, and more ecofriendly substitute for peat). "Nepenthes" will grow in orchid compost or in pure "Sphagnum" moss. Carnivorous plants are themselves susceptible to infestation by parasites such as aphids or mealybugs. Although small infestations can be removed by hand, larger infestations necessitate use of an insecticide. Isopropyl alcohol (rubbing alcohol) is effective as a topical insecticide, particularly on scale insects. Diazinon is an excellent systemic insecticide that is tolerated by most carnivorous plants.
Aspasia (plant) active growth. They need at least 75% of humidity and good ventilation all the time. Moderate weekly fertilizing with a balanced formula is beneficial during active growth. They may be potted in a compost of half-chopped Sphagnum, vegetable fiber, and some medium-sized lumps of charcoal, or mounted on plaques of vegetable fiber, however, if mounted, they will need more frequent waterings. The genus "Aspasia" was proposed by John Lindley in 1833 when he described its type species, "Aspasia epidendroides". The name of the genus is a reference to Aspasia of Miletus a friend of Pericles. Its original description is very
