Artichoke - Imperial Star - Cynara scolymus
Tender Perennial Imperial Star was bred to produce artichokes in one season as an annual, perfect for colder climates. In warm areas, zone 7 and up, treat as a perennial and leave for 6-7 years until they need to be divided. Grow as a dramatic part of an edible landscape, or in rows. Their ideal climate is a moist, coastal area.

Planting & Care
Soil & Water: Artichokes need rich soil with good tilth and drainage. Add compost months before you plant the seeds, balanced fertilizer just before planting, and nitrogen fertilizer throughout the growing season. Water thoroughly once a week, wetting entire root system.
Planting & Growing: Sow indoors 8-12 weeks before the last frost. Place seeds 1/4" apart and 1/4" deep in moist soilless mix in 2-4" containers. Grow at 60-70°F daytime and 50-60°F nighttime. Transplant 6-8 week old plants 4'-6' apart, in rows 8' apart or as part of an ornamental landscape. Time the transplanting so plants get 8-10 days of 50°F for vernalization to promote budding. Protect from frost. Direct sow: if winter low is above 14°F plant seeds in fall in moist soil and harvest in spring.
Harvesting & Storage: Cut artichokes when they are 2"-4" in diameter, leaving a stem of about 2". Refrigerate up to 3 weeks.
Limited Guarantee for Dormant Trees & Plants
What We Guarantee
What we guarantee, and our only guarantee, is that your dormant tree/plant will arrive in viable condition and will leaf out by May 15th. Historically, 98% of our trees & plants do. If your tree/plant leafs out and then dies, it is no longer covered by our guarantee. We only warrant to the extent of the purchase price, that the dormant tree/plant sold hereunder is as described in the catalog, website or label within recognized tolerances. No other warranty is given, expressed or implied of (1) the merchantability or fitness of the tree/plant for any particular purpose, or (2) against loss due to any cause. Our guarantee is only available to customers who have purchased their dormant trees directly from us.
What We Do NOT Guarantee
We do not guarantee your success of keeping your tree/plant alive or having your tree/plant bear fruit, as there are too many variables beyond our control to be able to do so. We cannot and will not accept any responsibility for the many growing and climatic conditions (soil preparation, planting, fertilization, weed and pest control, adequate irrigation and/or drainage, chill hours, compatible hardiness for your zone, proper choice of pollinator, etc.) that must be met to ensure the success of your tree/plant.
Deadline for Credit
Credit claims for trees/plants that arrived in unviable condition must be received within 3 days of delivery. Claims of this nature that are received more than 3 days from delivery will be automatically denied.
Credit claims for trees/plants that did not leaf out by May 15th must be received by June 1st (at the very latest) for consideration. Due to their tendency to bloom later, persimmon trees have a deadline of June 15th. Claims of this nature received after the June 1st deadline (or June 15th for persimmon trees) will automatically be denied.
How to Request a Credit
If your dormant tree/plant arrives in unviable condition, you must contact us within 3 days of delivery to receive a refund or exchange (if available).
If your tree/plant does not leaf out by May 15th, please contact us as soon as possible (before June 1st) by email (email@example.com) or phone (800-784-1722). We will issue you a one-time credit (not a refund) for the price you paid for that tree/plant (excluding shipping). This credit is redeemable toward the purchase of any other dormant tree/plant of your choosing the following season.
We reserve the right to not issue credit for items purchased with credit. We also reserve the right to require you to perform a scratch test, and/or to provide photographic evidence of the condition of your tree/plant. The scratch test consists of checking for green under the bark a few inches over the graft (please watch our video titled Bare Root (Dormant) Warranty for more information on this simple procedure). If the scratch test reveals a brown cambium, the tree/plant is dead or dying. If we require photographic evidence of the condition of your tree/plant, we will need photographs of the entire tree/plant (including the roots). Please email these photographs to firstname.lastname@example.org. We reserve the right to deny your claim for credit if we determine, from your photographs, that there is damage to the tree/plant due to rodents, root rot, mechanical equipment, or any other source beyond our control.
