Cynara Species, Artichoke Thistle, Cardoon

I planted this about 3 years ago, I am impressed and happy with its interesting architectural form , and the flowers are beautiful. My s...Read Morepecimen is now over 6 ft tall and has at least 8 or 9 flower buds. It is planted in a well drained bed that has not had many soil amendments added. It has survived through the few snow and ice events we have had in the past 2 winters.

A friend gave me about 14 dried cardoon flowers for an arrangement I put on my barbeque outside on the back porch. The next spring I had...Read More about 20 baby plants. I didn't even know what these babies were because I didn't plant any seeds in the bed where they were. It took me a while to figure out the dried cardoon flowers that blew apart in the winter winds had scattered the seed. Very prolific so watch out and remove flower heads after the bloom.

Dead heading is imperative but we toss the heads back under the hedge for next years show. Stunning plant!

I like a few things about this plant. It's low-maintenance. I am in Northern CA (Zone 8) and get no rain from April to October. My card...Read Moreoons grow without irrigation in very poor clay with no amendment. They grow in shady areas that get only 3 hours of direct sun in the summer, none in the winter. They produce a large amount of material for compost per plant. I just chop off the leaves when they droop. I'm a beekeeper, and the bees love this plant. It produces a large amount of nectar and is good bee forage. The comments about its invasive nature are right on, though.

Still, I love the jagged silver leaves, especially during winter in my 7b/8a garden.

The plant's summer blooms are endearingly amusing, like a purple punk hairstyle. After flowering, cardoon seems to shrivel and die, but it's only resting until the weather cools in the fall.

Hi:
I am wondering if I can keep this plant in my indoor garden room for the winter here in Vancouver, WA Zone 6? I will put it ou...Read Moret again in the spring. Any ideas would be helpful.

Has anyone tried to collect the dried seeds directly from the dried flowers/thistle? If so, can you share success/failure stories?

Thanks

Planted two plants (app 10 inches tall) late in the summer, but neither survived the winter cold.

The next year, I experienced the invasive side as baby cardoons came up everywhere in my vegetable garden (easy to identify and pull). I skipped a year and have decided to cautiously allow one to grow in the back of my bed for the entertainment value, and to feed my beloved chickadees and finches. One other person in town has been growing them for several years and they don't seem to have posed an invasiveness problem here in ecologically delicate Provincetown MA. I'll keep you posted, but for the meantime any bird&bug lover who enjoys a spectacular thistle may enjoy growing a cardoon or two....

Since I have only had it for about a year, can't say anything about its invasiveness. so far no problem. Planted inground, full sun. As of this writing, plant is in bloom, it is all I can do not to cut the flower and bring it inside the house. Quite stunning!

DO NOT let this plant go to seed b/c the seed are carried by animals, especially birds and mice making nests and they carry on the wind. If seeds gets away, cardoon will sprout anywhere it lands.

Japanese beetles target this plant. Other then other beetles, I haven't observed other pests.

At the end of the season I dug out and destro...Read Moreyed all of them, or so I thought, since I did not believe that they would survive our harsh winters. To my surprise, one came back from what must have been left of the the roots and grew into a glorious plant over the last few months. It is now blooming with about a dozen flowerheads, and reaching about 6ft tall and 5 feet wide. Has anyone else had a cardoon survive a zone 5 winter?

We bought a house that came with a large (20' x 40') garden last summer... we weren't sure what would grow this year, so I took a "wait ...Read Moreand see" approach.... well, we have/had cardoon and my FIL actually knew what it was, etc. so I had planned to blanche some of it, and harvest it. It grew to about 6 ft tall, and a huge rainstorm flattened just about all of it. Part of it fell over into the "lawn" portion of our yard, and proceeded to sprout in the grass, so we pushed it all back into the garden. Because it is so attractive to bees, I had to wait until this past weekend's 70 degree/cloudy weather to pull it out. New growth had started to grow from the now flattened, but not dead stalks. It's quite hardy and that's not a good thing. 5 hours and 14 plastic garbage bags later, it is mostly gone... we chose plastic over paper leaf bags to avoid spreading it to anyone else in our town. We have since found more cardoon growing in all parts of our garden, lawn, and other parts of the yard. If you choose to grow cardoon, make sure you tend to it daily, and you want it. We were unlucky that we didn't know what was what and we had never gardened before. Our variety was quite spiny and even wearing leather gloves, my forearms were "stuck" over and over again and appear to have a rash.

It is great for flavoring rice dishes and stews. It is also great by itself, but stronger tasting than the artichoke.

Since then the Hirabara Farm (small boutique farm) where the demonstration/cooking class took place, has been continuing to grow it. The farm is located at about the 3,000 foot elevation

This makes the leaves and stems to loose their greygreen colour and it softens the stems.
Cynara cardunculus is a delicate vegetable although it requires a long boiling time over 2 hours or 50 minutes in a pressure cooker. Note that only the stems (very well cleaned) are eaten and are cut in pieces of 6 cm. A good seed is "Plein Blanc", inerme from Clause, France, means Fully white, unarmed (not prickly).

This plant was in the front yard, near the street, and everyone commented on it.

The others only grew to about 3 feet, and none of them survived a very cold winter at almost a 1,000 feet high--Atlanta can be a very cold place indeed, in the winter, despite being in the South, and I was sad that they didn't come back, as this was a very attractive plant. Obviously it is not invasive in that climate. I tried eating some of the new leaves, as the Romans ate it, but they were very bitter.

The wide, plump, edible stems form loose stalks or heads like celery. Cardoons keep their vase shape until late in the season, when a branching ,gray-wooly central stem shoots up.
