Delphiniums bring that English country garden touch to yard

Spring is the time to shop for and plant these easy-to-grow perennials that can reach 6 feet tall.

If there is one perennial that personifies a cottage garden, I think it would have to be the delphinium.

They are what I think of when I picture a Victorian border or even just a simple country garden. Their tall stature often anchors the back of a bed and provides the height that is so critical in keeping the eye moving through a perennial landscape design. When I moved to the Northwest 30-plus years ago, I couldn’t wait to grow these beauties.

You see, growing up in Southern California only 15 miles from the Mexican border, the weather was not conducive to many perennials, like delphiniums. There was no distinct winter to force them into dormancy, so they just kept growing and getting leggier and leggier. For perennials to do their best, they really need to rest for several months, and that just doesn’t happen in Southern California.

In the Northwest, however, we have the perfect climate for growing delphiniums and a whole host of other fabulous perennials that can easily provide us with up to 10 months of nonstop color. This is accomplished by planting early-, mid- and late-bloomers and combining them so that there is a constant succession of flowers throughout the entire season. While most perennials only bloom for five to six weeks, delphiniums are special in that after their initial bloom in early spring, if they are cut back and fertilized, they will re-bloom again in late summer. Talk about bang for your buck.

You can find delphiniums in the garden center this time of year in many varieties; often they’re already budded up and showing color. Gallon-pot plants will have multiple stems, while 4-inch starts will only have one stem and will need another year to really get established. Plant them in full sun and don’t forget to stake them before a rain or wind storm knocks them down. As a side note, sometimes delphiniums are labeled as larkspur. But don’t get confused — true larkspurs are annuals and are much smaller in stature.

Despite all of the new introductions, my favorite is still one called “Black Knight,” which has midnight-dark violet blossoms and can reach 5 to 6 feet tall in the garden. The Aurora series is a wonderful collection with 3-to 4-foot stems that are very study and excellent for cut flowers. The color range runs from white to purple to various shades of blue, and each one has a white center (called a “bee”).

“Green Twist” from the New Millennium series is a new one that caught my eye the other day. It has large white flowers tinged green, with a white and green bee, often double or semi-double. The stems are sturdy, reaching 4 to 5 feet tall, and are great for arrangements.

One other series that I am impressed with is the Guardian strains. They only grow to about 3 feet tall, which is perfect for smaller gardens, but the flowers are large and double as well. Colors are white to shades of lavender and blue.

All delphiniums will attract hummingbirds and other pollinators, like butterflies and bees, and they are deer-resistant. Slugs can be a problem in early spring when the new growth is emerging, but after that they seem to do just fine. Feed them with a balanced organic flower food, give them lots of compost and they should be happy campers. If you can’t get them to live more than a couple of years, chances are they are staying too wet.

Now is the time to shop for delphiniums. Once they are gone, the nurseries won’t have them again until next year — and they are too wonderful to miss!
