A bed built around tulip 'Apeldoorn'
The planner designed this bed around tulip 'Apeldoorn' when this page was made: a 12 × 6 ft (3.7 × 1.8 m) English border in zone 6, full sun. It chose the other plants from the 966 that suit those conditions, and says below why tulip 'Apeldoorn' stands where it does.
The plants
- 1 Common thyme × 8, lavender
- 2 Heath aster 'Snow Flurry' × 9, white
- 3 Hyssop 'Blue Boa' × 3, purple
- 4 False sunflower 'Summer Nights' × 3, yellow
- 5 Inkberry 'Gem Box' × 1, dark green leaves
- 6 Wild geranium × 3, pink
- 7 Tulip 'Apeldoorn' × 5, red
- 8 Daffodil × 10, yellow
Why this plant
- A classic partner for daffodil. Both are on this plan. A pairing gardeners have proved outranks a general rule.
- The only red.
Why here
- In the middle. At 22 in it is the step between common thyme (10 in) in front and hyssop 'Blue Boa' (3 ft) behind: each is seen over the one before.
- 5 plants in one group. Massed, one kind reads as a single shape. Scattered, it would look spotty.
- Beside daffodil. A recognised partner: the planner puts such plants together where it can.
Why now
- In flower for three weeks. From late April to early May.
- Part of the bed's peak. With wild geranium and daffodil in early May: 3 kinds at once. No week has more.
- Leaves gone by midsummer. They die back and leave bare ground. A perennial that comes up late stands beside it, and grows over the gap.
Planned as an English border: 5 of the 6 groups (83%) are drifts, longer along the bed than they are deep. Hyssop 'Blue Boa' and false sunflower 'Summer Nights' anchor the back corners of the bed: the tallest plants on the plan stand there. Hot and cool in equal measure: yellow and red against lavender, purple and pink, with white to calm things between them.
The planner's own design check: 12 Excellent, 5 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where tulip 'Apeldoorn' goes in a border
At 22 in it belongs in the middle of a bed. In the planner's ten height classes it is medium short (18 to 24 in).
Its job: drift. Planted in a small group of three or five, and repeated further along in the other number.
The best-known Darwin hybrid, and the tulip to plant for one that returns: in good drainage and full sun it flowers for five years or more.

What to plant with tulip 'Apeldoorn'
Plants recorded as good partners for it, and what each pairing does:

- Grape hyacinth: in flower together for three weeks, from late April; fine leaves against its bold ones; low enough (6 in) to stand in front of it.
- Catmint 'Walker's Low': takes over when it finishes, flowering from mid May; grows up in time to hide its dying leaves; fine leaves against its bold ones.
Questions about tulip 'Apeldoorn'
Does tulip 'Apeldoorn' need sun or shade?
Tulip 'Apeldoorn' grows in full sun (6 or more hours of direct sun a day).
It wants ordinary well-drained soil, of average fertility, and a good soak in dry spells.
What zones does tulip 'Apeldoorn' grow in?
USDA zones 3 to 8. It is hardy to zone 3, which means it survives winter nights down to about −30 °F (−34 °C).
Above zone 8 it struggles: the zones measure winter cold, but a plant's top zone usually means the summers are too hot or the winters too mild for it to rest.

When does tulip 'Apeldoorn' flower in my zone?
In zone 5 it flowers late April to early May. As a spring flower it moves about a week for every zone: earlier where it is warmer, later where it is colder.
| Zone 3 | Early May to late May |
|---|---|
| Zone 4 | Early May to mid May |
| Zone 5 | Late April to early May |
| Zone 6 | Mid April to early May |
| Zone 7 | Mid April to late April |
| Zone 8 | Early April to mid April |
Worked out from Hopkins' bioclimatic law: spring arrives about four days later for each degree of latitude north, and one zone is roughly two degrees. A warm spring or a cold one moves any garden two weeks either way.
How far apart should tulip 'Apeldoorn' be planted?
5 in (12 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 6 in (15 cm), so a group knits into one patch.
It grows 22 in (55 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many tulip 'Apeldoorn' plants do I need?
At 5 in apart, set out in staggered rows:
- 74 to fill 10 square feet (about 1 m²)
- 26 for a single row 10 ft (3 m) long
- 238 to fill a 4 × 8 ft bed on its own
In a mixed border, plant it as a group of three or five, with a second group further along in the other number.
In the bed above, the planner used five in one group.
Is tulip 'Apeldoorn' poisonous to dogs and cats?
Yes: moderate toxicity to dogs, cats and horses. The bulbs are the most poisonous part and cause vomiting, drooling and diarrhoea in pets. Handling the bulbs can irritate skin.
Rated from the ASPCA. Where references disagree, the more cautious rating is used.
What can I plant to hide tulip 'Apeldoorn''s leaves after it flowers?
A bulb's leaves have to be left to yellow for about six weeks after flowering, to feed next year's flowers. Plant it among perennials that come up late and spread wide, and they grow over the leaves as they fade:
- Catmint 'Walker's Low': 24 in tall and 2½ ft wide, a recorded partner, in flower mid May to mid September.
- Garden chrysanthemum: 24 in tall and 24 in wide, in flower mid September to late October.
- Lady's mantle: 18 in tall and 24 in wide, in flower late May to early July.
What does tulip 'Apeldoorn' look like in winter?
Tulip 'Apeldoorn' is underground: it dies back after flowering and waits as a bulb until spring. Mark where it is, so a fork does not find it first.

Checked against ASPCA poison lists. Flowering times are for zone 5: later in colder zones, earlier in warmer ones. Toxicity and spread information is a general gardening guide, not veterinary or medical advice, and invasive status varies by region. If a person or pet eats a plant, contact poison control or a vet. Check your local invasive species list before planting anything with a spread warning.
