Product Details

Product Details

Wide, smooth petals of brilliant blue surround a gently ruffled white eye on this Delphinium elatum 'Blue Nile,' an award-winning member of the Blackmore & Langdon series. A stunning vertical accent for sunny beds and borders.

We are honored to welcome back this extraordinary line of exceptional Delphiniums that has been in development since 1901. While B&L’s achievements with Delphiniums are less well known than their triumphs in the Begonia world, the same high standards apply here. Through recent advances in breeding techniques, these plants are now more vigorous, their blooms are vivid and refined, and the flower spikes are strong and graceful. B&L Delphiniums are available in the US only at White Flower Farm. Supplies are limited, so order early. Exclusive.

Delphiniums require full sun and rich soil amended with lime. In the South, they are best planted in the fall and treated as cool-season annuals.

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. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the 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. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Very happy and healthy plants!

I ordered these for spring 2023. Very healthy plants and immediately took to my prepared garden beds. I did have to add some extra slow release fertilizer,but that’s on me. They are shorter than I thought, but most gardeners know the first year isn’t usually the best show due to plants needing to focus on roots! My hummingbirds and I are thankful for the small bounty we still got in this first year. My delphiniums I ordered last fall (2022) are growing like crazy so I have no doubt next spring these will be in full glory!

Mine are great.

I read the reviews about this Delphinium from disappointed customers and I think it must have been a bad year — I ordered 3 this year (2022) and they're wonderful. Tall, vibrant blue, a little variation from plant to plant, healthy and strong the first year. Looking forward to seeing them get established.

I ordered a total of six Delphinium elatum in three different colors, planning to plant them as a group. They arrived in staggered shipments and two of the plants were dead when they arrived (WFF refunded $). Two plants are already blooming (the Blue Nile) but are not the 5-6 feet tall as described. They are less than 3 feet tall. Instead of the grouping of towering plants I had anticipated, I have two straggly looking plants blooming, with two more that look like they will bloom in a couple of weeks. I usually love the plants I get from WFF, but am really disappointed with these, especially in view of the cost.

Rootbound - Dried Out Mess

I ordered other Delphiniums from White Flower before with great success - I was so looking forward to receiving this one. When it arrived I immediately opened the box to find my three Blackmore & Langdon plants (all different) root bound, dry as a bone -- and incredibly small! This is what I get for $22.00? I am definitely disappointed. NOT up to the usual standard of this company.

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.
