Product Details

Astounding double Delphiniums with a breeding program to match! In fields in Holland, the Sahin Seed Company has been growing and blooming 75,000 seedling Delphinium plants each year for 20 years. Their uniform, upright Centurion strain is the result. The flowers give a very full effect as they are closely packed all around the sturdy stems and open in succession right to the top. You'll love them as cut flowers. 'Centurion Gentian Blue' offers double flowers in dark gentian blue with a contrasting bee.

The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it.

Can't Be too Wet, but Gorgeous

Maggie from New York City

Last year I had three of these delphiniums.

Two made it through a very, very tough winter in NYC. (And I'm gardening on a terrace with exposure to high winds and snow.)

I don't need to stake them. If given good care, they can stand on their own. And standing alongside roses, they are splendid!

First, like all delphiniums they need sand (dug into the soil and surrounding--but not on top of-- the plant.) This ensures good drainage.

Also, like all delphiniums, they need food. Feed monthly with 5-10-5. (or 10-20-10) Yellow leaves indicate that they are not getting enough--feed more!

For this particular delphinium, all of the care is worth it. It is so beautiful-and, when happy, it is hardy. It was blooming--putting out new flowers --in late October. (In the past, I have given up on some other delphiniums)

Glorius Blue!

Aly from Pittsburgh, PA

This Delphinium has been a great performer. The color is so vivid; it's a standout in my front garden. I have not had such good luck with other delphiniums, but have had this for 3 yearts and it's still going strong - in spite of our drought conditions.

Extra beautiful bloom

Linda from Dayton, OH

This is a beautiful delphinium. The color has a hint of violet that makes it electric. It stands out - even from a distance.

Mine has only morning sun and the location is too dry. I bought 3 and they had small blooms the first year. Only one of the three I bought lived through to bloom this second year.(I accept this as my own fault) This year the one plant has several blooms. I learned also that they need to be staked - but this one kept blooming after being knocked down and then propped up.

I will probably buy more of these next year - and put them in a less dry location.

Too delicate for its height

Sue from Mechancsburg PA

I use this as a highlight through color and height in my garden. It's been a bit fragile this summer and previous summers. I wish the stalk were stronger

Latin Name Pronunciation: del-fin'ee-um 

Delphiniums require full sun, preferably in a spot protected from high winds. They also need very fertile soil, with a pH close to neutral. If your soil is acid, plan to mix a handful of lime into the bed. And, lastly, all of the tall varieties require staking. Inevitably, a sudden downpour will knock unsupported stems down into the mud, and there's no way to ease that heartbreak. We suggest using two or more loops of twine, arranged in a figure-8, starting near the base and ending just below the flower head.

"Very fertile soil" means soil enriched with plenty of compost or composted manure. Plan to add a balanced, slow-release fertilizer as well.

Yes, Delphiniums require more attention and preparation than some other perennials. But, as our founder wrote, "… no gardener worth his loam would stop growing Delphiuniums just because they are not as rugged as weeds. There is nothing more beautiful or more rewarding …."

Cut the flower stalks of all but D. grandiflorum 'Blue Mirror' to the ground immediately after flowering for a second, smaller show in September. D. grandiflorum 'Blue Mirror' is the best Delphinium for the South but is short-lived there; allow a few plants to go to seed to provide for replacements.

Combine with Peonies, Siberian Iris, Lupines, Shasta Daisies, Roses, and other June bloomers.
