Some tulips are memorable because they are unusual. ‘Oxford’ is memorable because it does the traditional things extraordinarily well.
Its great flowers are a rich, glowing red, carried high on stout stems above broad green foliage. When the flowers open in the spring sunshine, they reveal a striking interior: a dark, nearly black center surrounded by golden yellow. The combination gives an otherwise classic red tulip considerably more character than one might expect at first glance.
‘Oxford’ is also one of the old stalwarts of the Darwin Hybrid class—a group that changed the way tulips were used in gardens and landscapes during the twentieth century.
When Was ‘Oxford’ Introduced?
‘Oxford’ was introduced in 1945, making it an old cultivar by the standards of modern commercial tulips. Horticultural references continue to list that date, and ‘Oxford’ has remained in cultivation for more than 80 years.
That longevity tells us something.
Tulip cultivars come and go with remarkable frequency. A variety introduced this year may be difficult to find a decade or two later. A tulip that survives in commerce for generations has generally done so because growers and gardeners continue to find it useful.
‘Oxford’ certainly qualifies.
Why Is It Called ‘Oxford’?
The name naturally brings to mind Oxford, England, and particularly the ancient university city.
Unfortunately, the precise reason the name was chosen is not well documented in readily available primary sources. I have not found an original breeder's statement saying, in effect, "We named this tulip Oxford because..."
So we should distinguish between what is known and what merely sounds plausible.
The cultivar is unquestionably called ‘Oxford’, but we cannot safely claim that it commemorates Oxford University, a particular college, an individual associated with Oxford, or some historical event without better evidence.
There is nothing unusual about European tulips receiving geographical names. The famous Darwin Hybrid ‘Apeldoorn’, for example, bears the name of a Dutch city. ‘Oxford’ may simply have been intended to evoke the English city and the prestige associated with its name.
It certainly has a rather scholarly ring to it.
One might even say that among red tulips, ‘Oxford’ has excellent credentials.
What Type of Tulip Is ‘Oxford’?
‘Oxford’ belongs to the Darwin Hybrid Group.
The Royal Horticultural Society describes Darwin Hybrids as tall tulips producing large, single, ovoid flowers in mid- to late spring, and specifically places ‘Oxford’ in this group.
Darwin Hybrids originated from breeding involving the old Darwin tulips and Tulipa fosteriana. This marriage produced something gardeners badly needed: large flowers combined with vigorous plants and sturdy stems.
The result was one of the great achievements of twentieth-century tulip breeding.
‘Oxford’ typically grows around 20 to 24 inches tall, though conditions affect ultimate height. Modern landscape bulb catalogues commonly list it at about 60 cm, or roughly 24 inches.
These are not little tulips intended to disappear among pansies.
They have presence.
A Remarkable Red Flower
‘Oxford’ is usually described as vermilion or bright red.
But the exterior color is only part of the story.
When the flower opens, the interior reveals a golden-yellow base surrounding a nearly black center. The Pacific Bulb Society specifically notes this combination of large red flowers, yellow base and black center.
On cool or cloudy days the flowers remain more tightly cupped, presenting a comparatively restrained red display.
Then the sun appears.
Darwin Hybrid flowers open substantially in warm sunshine, and a bed of ‘Oxford’ suddenly exposes those yellow and black centers. The appearance of the planting can change dramatically over the course of a spring day.
It Is Also Fragrant
Here's something easily overlooked when discussing tulips: ‘Oxford’ is fragrant.
Tulips are seldom planted primarily for fragrance, and many cultivars possess little noticeable scent. ‘Oxford’, however, is among the Darwin Hybrids reported to have fragrance.
That gives the gardener another reason to plant it somewhere the flowers can be approached closely rather than relegating the entire display to a distant corner of the property.
A planting along a walkway or near a terrace allows both the size and the subtler qualities of the flowers to be appreciated.
One of D. W. Lefeber's Favorites
There is another interesting piece of ‘Oxford’ history.
The great Dutch tulip breeder D. W. Lefeber was enormously important in the development of Darwin Hybrid tulips. A horticultural paper discussing tulip collections notes that many Darwin Hybrid varieties were discovered or developed by Lefeber—and identifies ‘Oxford’ as his favorite variety.
That is quite an endorsement.
Lefeber worked with some of the most important tulips of the twentieth century. If ‘Oxford’ stood out among them, there was evidently more to this red tulip than meets the casual eye.
How to Use ‘Oxford’ in the Landscape
‘Oxford’ is first and foremost a landscape tulip.
Its tall stems and large flowers allow it to be seen from a considerable distance, which makes it especially useful in broad beds and borders.
The RHS recommends ‘Oxford’ for flower beds and borders, cottage and informal gardens, courtyard gardens, coastal gardens and containers.
But I think its finest use is mass planting.
Plant five bulbs and you have five handsome red tulips.
Plant twenty-five and you have a display.
Plant fifty, a hundred or several hundred in broad drifts, and you begin to use ‘Oxford’ as it deserves to be used—as a genuine landscape plant.
The brilliant red is strong enough to carry across a lawn or large garden.
Red Requires a Little Discipline
A powerful red such as ‘Oxford’ should be placed deliberately.
One of the best combinations is red and white. White tulips or white narcissus provide a crisp contrast and prevent a large planting of red from becoming visually heavy.
Cream and ivory provide a softer version of the same effect.
Yellow is another natural companion because the golden interior of ‘Oxford’ already introduces that color. A yellow Darwin Hybrid planted alongside it can produce an exceptionally cheerful traditional spring display.
For greater drama, try deep purple or nearly black tulips. Their darkness gives the brilliant red greater depth.
And don't overlook blue. Low-growing grape hyacinths (Muscari) can form a blue carpet beneath the tall red flowers.
Red above blue is a bold combination, but spring is no time for excessive timidity.
Plant It in Broad Drifts
Because ‘Oxford’ is tall and strongly colored, it works particularly well when planted in irregular drifts rather than little isolated clumps.
Imagine a broad ribbon of red moving through a perennial border, disappearing behind a shrub and appearing again farther along.
That is considerably more effective than placing six bulbs here, five there and three somewhere else.
For a formal garden, of course, the opposite approach may be appropriate. ‘Oxford’ can be planted in regimented beds or geometric blocks, where its uniform height and strong color create the sort of disciplined spring display traditionally associated with grand gardens and public parks.
It is quite capable of behaving itself when required.
A Good Tulip for Perennial Plantings
One of the great advantages of Darwin Hybrids is their reputation for returning in subsequent years.
No modern hybrid tulip should be promised the permanence of a daffodil. Climate, soil, drainage and summer conditions matter enormously. Nevertheless, Darwin Hybrids are generally among the better modern tulips for gardeners hoping for repeat flowering.
Their vigor is one reason they became so important for landscape use. Darwin Hybrids are frequently recommended for naturalizing or perennial-style tulip plantings where conditions are favorable.
For the best chance of return, plant ‘Oxford’ in full sun and well-drained soil, remove spent flowers before seed develops, and leave the foliage untouched until it yellows naturally.
Those leaves may not be beautiful in June, but they are doing useful work underground.
Use Perennials to Hide the Fading Foliage
The traditional solution to declining tulip foliage is still the best one: plant something in front of it.
Place ‘Oxford’ among perennials that emerge vigorously as the tulips finish flowering. Hardy geraniums, peonies and similar plants can gradually conceal the yellowing foliage.
The tulips dominate the border in spring.
Then the perennials take over.
A well-planned garden should work rather like a good play: one character exits while another is already entering from the wings.
Excellent for Cutting
‘Oxford’ also makes an excellent cut flower.
Darwin Hybrids possess the long stems, large flowers and strong construction florists want, and ‘Oxford’ brings an exceptionally useful red to arrangements.
A simple vase containing a dozen stems can be spectacular.
For a more traditional arrangement, combine ‘Oxford’ with white or yellow tulips. For something moodier, add dark purple flowers and spring foliage.
Growing ‘Oxford’
Plant the bulbs in autumn, preferably after the soil has cooled.
Choose fertile, well-drained soil in sun and protect tall tulips from severe wind where possible. The RHS recommends planting tulips approximately 4 to 6 inches deep and particularly warns against excessive wet.
Poor drainage is one of the surest ways to turn an expensive tulip planting into an underground bulb-rotting experiment.
Where winters are too warm to provide sufficient natural chilling, bulbs may require pre-chilling before planting.
The Oxford Family
The name ‘Oxford’ also appears among related Darwin Hybrids.
‘Golden Oxford’, for example, is a bright yellow Darwin Hybrid and remains commercially important enough to appear regularly in modern bulb catalogues.
There are also cultivars bearing names such as ‘Red Oxford’, ‘Oxford Elite’ and ‘Oxford Wonder’, illustrating how the success of established cultivars often leads to sports, selections and related commercial introductions.
The old red ‘Oxford’, however, remains the classic.
A Red Tulip That Has Earned Its Place
‘Oxford’ doesn't depend upon novelty.
Its flowers aren't fringed, feathered or twisted. It doesn't resemble a peony. It doesn't change through half a dozen colors as it matures.
Instead, it gives us the virtues that made the Darwin Hybrids famous: large flowers, tall sturdy stems, vigorous growth, strong landscape performance and the possibility of returning in subsequent years.
Add brilliant red petals, a golden-yellow base, a black center and even a little fragrance, and it becomes easier to understand why ‘Oxford’ has survived since its introduction in 1945.
And there is one final recommendation worth remembering: among all the Darwin Hybrids associated with the legendary Dutch breeder D. W. Lefeber, ‘Oxford’ was reportedly his favorite.
A tulip breeder could hardly give a tulip higher praise.
More than eighty years later, ‘Oxford’ is still making a convincing case for itself.
