Clematis (Clematis Tangutica) - Clematis seeds produce a wonderful, vining flower that is a long-lived perennial, normally living at least 25 years. The top of the Clematis vine should be exposed to full sunlight with the roots shaded by either a ground cover or a mulch such as bark dust. Clematis Tangutica is tolerant of poor soil but needs to be well watered. This Clematis plant will flower within 3 - 4 months of planting the flower seeds, and the second year it will produce significantly more blooms. The 3 inch yellow blooms also produce feathery silver seed heads. This vine is great for trellises and arbors, and also does well in containers as an annual. This Clematis plant will both summer and fall. Sometimes it is called Golden Clematis.
Clematis flower seed takes about 21 - 28 days to germinate. You can sow the flower seeds in trays indoors and transplant the seedlings after frost season, or sow the flower seeds directly outside after danger of frost has passed. Before sowing Clematis seed, refrigerate the seed for 2 - 3 weeks. Some gardeners prefer to start the flower seed outdoors in the late fall or in the winter in a cold frame. The cold helps to break the dormancy.
