Lady Margaret Passion Flower is a species with large red flowers, among the most sought-after passionflowers. It is a hybrid between Passiflora coccinia and Passiflora incarnata. Although the flowers are not the brilliant blood-red of the Red Passion Flower, they nevertheless stand out dramatically, a deep purplish red, with prominently marked corona not found in other red-flowering passionflowers. Flowers are 7-9 cm across. Sepals are green outside, deep purplish-red inside, oblong, 3.3-4 cm long. Petals are oblong. Leaves are 3-lobed, 6.5-15 X 7.5-16 cm, with toothed margin.
