Graham's butterfly orchid

In cool temperate regions, grow outside in summer in containers or in a sheltered sunny border in light, fertile, well-drained soil, or in a conservatory or cool greenhouse (ventilate when temperatures rise above 7-10°C) in a coarsely draining, medium-fertility, loam-based mix, in full light with shade from hot sun or in bright filtered light; water sparingly in winter and plentifully when in full growth but without overwatering, and apply a dilute high-potash liquid fertilizer every two weeks; unlike other Schizanthus, S. grahamii is better grown on without pinching out

No pruning required, but good as cut flowers

Propagate by seed sown at 13-16°C in mid-spring for plants flowering in summer, or in late summer for plants grown for winter flowering under glass, and pot on regularly so that plants are in their final pots by late autumn

Generally pest-free, but may be affected by aphids

Generally disease-free, but may be affected by wilts, leafy gall, powdery mildews, crown, foot and root rots, and virus diseases such as tomato spotted wilt
