What flower is this?
 

I would like to get some for my garden next year. They are very tall. I would say 6 feet at least. Saw them at the Castle in the clouds on Saturday. Looked like a daisy of some type.

Coreopsis?
 

Looks like one of the taller varieties of coreopsis. I have one similar in my garden, but I also have the moonlight variety which is shorter (and I like much better).

I Agree with beagle
 

This looks like a variety of Coreopsis. They are a wonderful flower, but require dead heading or stalking for longer blooming.

The heart shaped foliage and form makes me want to pin it down as being some form of perennial helianthus (sunflower family).

I'm only aware of one coreopsis type that gets anywhere near that tall and it's actually a pretty ugly plant. :emb:

Helianthus tuberosus or . . .
 

Jerusalem artichoke. When I was a kid, living on a farm, we had these growing in many different spots. They were taller than I was back then and came up year after year with no care at all. My kind of perennial, plant it and forget it!

Jerusalem Artichoke
 

Quilt Lady has it right. Grows 4+ feet tall, and you can harvest the edible roots to eat. They are like mildly nutty, mild potatoes.

This Plant Sounds Great!
 

Are they invasive and what kind of sun do they require?

In the book, Stalking the Good Life, Euell Gibbons tells of artichoke pickles.

“The artichokes are peeled, then packed in quart jars. I pour a cup of cider vinegar in each jar, then fill with cold water, add one clove of garlic, one red pepper, and a teaspoon of dill seed. That’s all. I just cover the jars and put them away to pickle.”

Childhood memories
 

"Crunchy Euell!"

Thanks. My wifes father said it was a something artichoke and I said "No way". Shouldn't argue with the father in-law I guess.....:rolleye2:
