Heleniums are fast becomi g a favourite for me.
No don't divide until spring. I,wouldn't plant out now until spring either
There are a couple of helenium specialists out there...just the in heleniums and they are there.
Look through the descriptions and narrow,down your choices with regard to neighbouring plants likely to be there.
Good soil produces good plants. Soil that won't get waterlogged in winter but will hold some moisture in spring and summer Then you can grow them in the sun. Their foliage can get tatty so think about something to grow in front of them....yes, rudbekias are good. Aster frikartii monch too, lobelias like Tanya, Hadspen purple, Queen Victoria , anemone wild swan, deschampsias. Acteas, dahlias and tall grasses like miscamthus, and Calamagrostis plus veronicastrums and tall salvias like uliginosa will create equal or taller height too.
Moreheim beauty, sahins, el dorado, hot lava, ....well a few others too....all add different colours to my garden and have been for,most of,the summer.
Did I say? I'm quite fond of heleniums
