Sunflowers are annuals or herbaceous perennials from open spots in prairies and sunny mountain meadows throughout North and Middle America. They develop numerous and very colorful, usually bright yellow flowers on medium to very all stalks throughout summer. Many species are excellent cut flowers. Helianthus are easily cultivated in any rich, well drained soil in a sunny spot. They are fast growing, very robust and adapt very well to various soil types.
Sow flat in any rich, well drained soil. Keep pots in a sunny , protected spot outside. Several perennial species require a cooling period of several months prior to germination. If these species are sowed late in the year, they do not germinate before spring in the following year. Transplant annuals to the final spot in the garden after the last freezing nights in late spring, perennials are best transplanted as soon as the leaves have withered in late summer to autumn.
All are USDA Climate Zone 6.
