Veronicastrums and heleniums
I am growing for,the first time veronicastrum and heleniums. Potted them up into 3 litre pots today for plantIng out in redesigned border Later. The veronicastrums are grown for their spikes in summer....grow tall grasses and other spikey subjects....and wonder what members think of them. Heleniums are a bit of a gamble ....slightly invasive I think and not too convinced about the wisdom of growing them. Do I kindly give them away, if invasive, or do I keep them?
