Helianthus ‘variety unknown’

To swap with Woolysage

This grower is sure of this plant identification.

This is a perennial variety (comes up every year) - an amazing herbaceous plant that grows over 6' tall and is smothered in yellow flowers from late summer till the frosts. Easy in full-sun, but beware - it can become invasive.

Grower Notes

These will be available as soon as they show themselves above ground - but that won't be for a few weeks yet. They die down over the winter, and only the root survives, but they will reach their full height this year.

    I am particularly interested in perennial edibles and scented plants. I grow perennials from seed, so often have seedlings of these. I also divide established plants so have these from time to time.
