This plant is similar to and often marketed as Passiflora amethyst.
Passiflora Lavender Lady performs best with full sun exposure. It is best outdoors where it can receive sunlight all day unimpeded. It requires full intensity sunlight to avoid issues that keep it from reaching its full potential.
Symptoms of a lack of full sun include:
Spindly, leggy growth
Failure to thrive
Indoors, Passiflora Lavender Lady may not get enough light unless it is in a solarium, greenhouse or next to bay windows.
