Pansies through the year
Against the frost risk in Lahore
Why these dates
Start indoors twelve weeks before the last frost and plant out four weeks before it - pansies want cool soil and stop flowering in summer heat. For winter and early spring flowers, sow in midsummer and plant out in early autumn, six weeks before the first frost, so the roots establish before the cold.
Hardy to about -15C and flowers whenever the temperature rises above about 4C, which is why it blooms in midwinter in zone 8. Dies out in summer heat above roughly 30C rather than in the cold.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Pansies are timed from 12 weeks before that frost for an indoor start, with planting out 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Lahore.
Lahore sits in zone 10b, which is milder than this crop wants, and a winter that never really arrives is its own problem. The dates below still describe the right time of year; the open question is survival rather than timing.
