Clematis flower seed is a long lived perennial, normally living at least 25 years. The top of the vine should be exposed to full sunlight with the roots shaded by either a groundcover or a mulch such as barkdust. It is tolerant of poor soil but needs to be well watered, and will flower within 3 - 4 months of planting. The 3 inch yellow blooms also produce feathery silver seedheads. It is great for trellises and arbors, and also does well in containers as an annual.
Clematis flower seed takes about 30 days to germinate. You can plant in trays indoors and transplant, or plant directly outside. A hole needs to be dug about 18" deep by 18" wide and filled at least with a third compost. This will allow the roots to develop well and spread out.
