They can be propagated by either seed or cuttings. Both are easy. For seeds, just take ripened pods and let them dry. Sow after the last frost in spring.

For cuttings, scroll down to the last page. It was intended for the propagation of varieties that can't set seed, but works fine for common varieties.

My yard is filled with Memories...... The onion chives my grandfather used daily, The Peony of my grandmother, the Queen Ann rose of a great aunt. the grape vine of my father the list goes on and on but each plant reminds me of good times spent with this person. IT is not important that it be the EXACT plant or clone of the plant BUT that it be the same type... so growing nasturtinus from seed or cuttings of the plant is not as important as the memories that will flow over you when you see any nasturtin from any source.
