Harvest Tips
Cut flowers in early morning when stems are fully hydrated; choose stems with several flowers already open and many buds remaining; cut at a 45-degree angle; strip lower leaves; immediately place in cool water. Stocks make exceptional, long-lasting cut flowers (7-14 days in a vase) and are ideal for arrangements. For seed saving, allow a few flower spikes to fully mature and dry on the plant; harvest seed pods when brown and papery; dry indoors and extract seeds.
