Helianthus Capenoch Star with Helenium Konigstiger © 2010 SpecialPerennials.com All rights reservedHelianthus:

Common Name: Perennial Sunflower.

These are the perennial relatives of the well-loved, towering sunflowers of our childhoods. They make great  long flowering, trouble free subjects for the back of a sunny border. They will also grow well in dappled shade. 

Most are great in dry soils.  

Great for bees.

Most spread slowly - some do run a lot (e.g. laetiflorus). Cut down the stems in early winter. Lift and divide every 2 or 3 years otherwise the plants can be very difficult to break up.  Some are said to be less hardy than others. In very cold winters the new buds at the soil surface can be damaged, but in my experience the plants recover well but may be a little later to flower. 

Some species have chocolate scented flowers. This is only really noticeable if you get your nose right into the bloom.

Helianthus Capenoch Star © 2010 SpecialPerennials.com  All rights reservedHelianthus Capenoch Star 

Large anemone-centred yellow flowers on 5ft, self-supporting plants. The outward facing flowers clothe the plants from July until autumn.

One of the most talked about flowers at our garden open days.

Capenoch is a grand estate in Dumfries. I'm (quite forcefully) told by a Scotsman that the pronunciation is "cape-nck"

RHS Award of Garden Merit.

Helianthus Happy Days 

Flowers exactly like Capenoch Star (above) but on short - 2ft 6in - plants that remain compact. This one has Plant Varietal Rights, which means we have to buy in young plants to grow on, so when they're gone, they're gone.

 

Helianthus Lemon Queen

Masses of pale yellow rayed flowers each 2-3in across. The upright plants are 4-5ft tall and self supporting. In flower from August to October.  Spreads to form a 2ft wide clump in two years. 

RHS Award of Garden Merit.

Helianthus Lodden Gold © 2009 SpecialPerennials.com  All rights reservedHelianthus Lodden Gold

Double golden yellow flowers from July onwards.  About 3 - 4ft tall depending on soil and position. Flowers well in sun or part sun. 

RHS Award of Garden Merit. 

Probably raised by Thomas Carlisle in the 1930's

Helianthis Monarch is great for a sunny, well-drained spot and bery attractive to beesHelianthus Monarch 

Large single golden yellow flowers from July onwards.  About 4-5ft tall. Flowers well in sun or part sun. If you want really large flowers you can remove some of the side-buds to concentrate energy into the central flower. Personally I don't have time!. 

RHS Award of Garden Merit.
