I had 'Twilight' for several years, a lovely old rose scent. I've tried to replace it along with 'Razzmatazz' another favorite of mine but it seems it's a.... in with new and out with the older introduced varieties, flash in the pan is what comes to mind with these ones so I've given up on them altogether.

I actually found an older post about the "secret" series after I had purchased and planted mine with people saying they aren't as robust, care-free or lush as other older varieties. It seems they don't care about those qualities which is very important in my garden so if it doesn't do good, it will go but hopefully I'll have a beautiful fragrant plant instead next year! :) here's hoping! and Thanks Annette, I love the smell of roses :)

I generally use Swallowtail Garden Seeds as my barometer for Echinacea cultivars. Since they rely on happy customers to buy their seeds, it suggests they have some idea which seeds deliver the desired results.

I've given up on most of the "designer" Echinacea cultivars simply based on my own experience: even winter sown seed-grown plants don't appear to survive beyond their first season. That says 'annual' to me.

I garden to sustain pollinators so fragrance isn't high on my list of priorities. If it smells good and attracts bees, butterflies and birds, I want to grow it in my garden.

Perhaps there are other, more reliable fragrant perennials that would suit your purposes. Impulse buys don't always return the expected results. Ask me how I know this to be true.

Echinacea Sombrero 'Hot Coral' smells good!
