About this cultivar:
Helianthus 'Capenoch Star' is a 1938 introduction name after a grand estate in Dumfries, Scotland (Apparently the pronunciation is "cape-nck"). It is similar to Helianthus 'Happy Days except it is taller, and the petals are larger. RHS Award of Garden Merit. We have it in one of my favourite parts of the garden (hence the multiple photographs!)

About this genus:
Helianthus (he-le-an-thus) from Greek helios (the sun) and anthos (flower), commonly known as the sunflower! Widespread natives to the America's that are primarily summer and autumn flowering perennials. Almost without exception, Helianthus blooms are yellow-flowered daisies.
Helianthus species are native from drought-prone prairies to boggy swamps and are renowned for their durability and adaptability. They are tough, low maintenance plants which makes them perfect for any garden. They'll grow almost anywhere that isn't a pond or full shade. The perennial Helianthus range from tall, back of the border plants to short front border specimens that really light up any garden. They have a reputation for being childish and in bad taste; I don't give a $#*! - That reputation might even be why I like them so much! I often toy with the idea of collecting all 70 of the species...
Helianthus flowers look amazing when the setting autumn sun shines through them...many insects agree and can't stay away. For non-insect companions try another Helianthus cultivar or tall grasses like Miscanthus. Late flower Aconitums. Daisies like Aster.Perhaps even Knipfohia.
