A bed built around garden phlox 'Jeana'
The planner designed this bed around garden phlox 'Jeana' 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 garden phlox 'Jeana' stands where it does.
The plants
- 1 Garden phlox 'Jeana' × 4, pink
- 2 Winter heath × 6, white
- 3 Coral bells 'Firefly' × 8, red
- 4 Anise hyssop × 5, lavender
- 5 Silver sage × 1, silver leaves
- 6 Golden ragwort × 8, yellow
- 7 Ornamental onion 'Purple Sensation' × 2, purple
- 8 Star of Persia × 3, purple
Why this plant
- The only dense clusters. The others are bells, airy sprays, spires and others. Shape reads at a distance, where colours blur.
- The only pink.
Why here
- Anchors a back corner. At 4 ft it is the tallest plant here, and the tallest close the ends of the bed, where they stand in front of nothing.
- A step in the back row. Next to golden ragwort (20 in) and anise hyssop (3 ft): no two neighbours there are the same height, so the back steps up and down like a skyline.
- 4 plants in 2 groups (3 and 1). Seen again further along, the same plant ties the bed together.
Why now
- In flower for 11 weeks. From mid July to mid September.
- Closes the season. For its last two weeks nothing else on the plan is in flower.
Planned as an English border: 7 of the 7 groups (100%) are drifts, longer along the bed than they are deep. Cool colours (pink, lavender and purple) with red and yellow as the warm notes, and white to calm things between them. Something is in flower for 35 weeks, from late January to mid September.
The planner's own design check: 15 Excellent, 2 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where garden phlox 'Jeana' goes in a border
At 4 ft it belongs at the back of a bed. In the planner's ten height classes it is moderately tall (3 to 4 ft).
Its job: drift. Planted in a small group of three or five, and repeated further along in the other number.
The individual flowers are half the usual size, but there are hundreds of them, and the leaves stay clean. If mildew has put you off garden phlox, grow this one.

What to plant with garden phlox 'Jeana'
Plants recorded as good partners for it, and what each pairing does:
- Purple coneflower: in flower together for nine weeks, from mid July.
- Joe Pye weed 'Little Joe': in flower together for seven weeks, from late July; bold leaves against its medium ones; happy in the same moist soil.
- Switchgrass 'Shenandoah': its green leaves are a setting for the flowers, before and after.
Questions about garden phlox 'Jeana'
Does garden phlox 'Jeana' need sun or shade?
Garden phlox 'Jeana' grows in full sun (6 or more hours of direct sun a day) and part sun (4 to 6 hours of sun, including some afternoon sun).
It wants soil that stays evenly moist, rich in organic matter, and a good soak in dry spells.
What zones does garden phlox 'Jeana' grow in?
USDA zones 4 to 8. It is hardy to zone 4, which means it survives winter nights down to about −20 °F (−29 °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 garden phlox 'Jeana' flower in my zone?
In zone 5 it flowers mid July to mid September. As a summer flower it moves about half a week for every zone: earlier where it is warmer.
| Zone 4 | Mid July to mid September |
|---|---|
| Zone 5 | Mid July to mid September |
| Zone 6 | Mid July to mid September |
| Zone 7 | Early July to mid September |
| Zone 8 | Early July to mid September |
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 garden phlox 'Jeana' be planted?
24 in (60 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 2½ ft (75 cm), so a group knits into one patch.
It grows 4 ft (120 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many garden phlox 'Jeana' plants do I need?
At 24 in apart, set out in staggered rows:
- 3 to fill 10 square feet (about 1 m²)
- 6 for a single row 10 ft (3 m) long
- 10 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 four in two groups.
Is garden phlox 'Jeana' poisonous to dogs and cats?
No toxicity is recorded for dogs, cats, horses or people, according to NC State Extension.
"Not toxic" is not "edible": a pet that eats a lot of any plant can be sick.
Do deer eat garden phlox 'Jeana'?
They may. NC State does not list it as resistant to deer or rabbits. Where they visit, protect it, or plant it among ones they avoid.
What flowers after garden phlox 'Jeana'?
Garden phlox 'Jeana' is over by mid September. These start as it finishes and carry the same spot on, so it never goes flat:
- Garden chrysanthemum: from mid September to late October, 24 in tall, to stand in front of it and cover its fading stems.
- Blue wood aster: from mid September to mid October, 3 ft tall, to stand in front of it and cover its fading stems.
- Montauk daisy: from mid September to late October, 3 ft tall, to stand in front of it and cover its fading stems.
What does garden phlox 'Jeana' look like in winter?
Garden phlox 'Jeana' dies down to the ground and there is nothing to see until spring. The old stems can be cut in autumn, or left until spring as shelter for overwintering insects.
Is garden phlox 'Jeana' good for bees and butterflies?
Garden phlox 'Jeana' is visited by pollinators, bees, butterflies and hummingbirds.
It is native to the United States (this is a named variety of the native plant).
