A bed built around bugleweed 'Catlin's Giant'
The planner designed this bed around bugleweed 'Catlin's Giant' when this page was made: a 12 × 6 ft (3.7 × 1.8 m) cottage garden in zone 6, part shade. It chose the other plants from the 513 that suit those conditions, and says below why bugleweed 'Catlin's Giant' stands where it does.
The plants
- 1 Bugleweed 'Catlin's Giant' × 9, blue
- 2 Dwarf lady's mantle × 8, green
- 3 Foxglove × 3, purple
- 4 Inkberry 'Gem Box' × 1, dark green leaves
- 5 Northern sea oats × 5, tan
- 6 Glory-of-the-snow × 12, pink
- 7 Giant snowdrop × 12, white
Why this plant
- The only blue.
Why here
- On the front edge. At 8 in it frames the bed without hiding it, and it is in leaf all season. It finishes 79% of the edge.
- 9 plants in 3 runs (5, 3 and 1). Runs of different lengths make the edge a frame, not a ruled line.
- Bold leaf against fine. Inkberry 'Gem Box' is beside it: the strongest contrast of leaf there is.
Why now
- In flower for five weeks. From early May to late May.
- Fills a gap. For four of those weeks nothing else on the plan is in flower.
Planned as a cottage garden: 26 of the 26 plants (100%), bulbs aside, stand alone or in groups of no more than five, small enough for the kinds to mingle. The front edge is finished with bugleweed 'Catlin's Giant' and dwarf lady's mantle. The flowers stay on the cool side of the palette: blue, purple, pink, green, tan and white.
The planner's own design check: 13 Excellent, 3 Good, 1 Satisfactory. It flags one thing to watch: Foxglove is highly poisonous to people, dogs, cats and horses. Northern sea oats spreads aggressively.

Where bugleweed 'Catlin's Giant' goes in a border
At 8 in it belongs at the front of a bed. In the planner's ten height classes it is low (6 to 12 in).
Its job: carpet. A groundcover planted in threes and fives to cover the soil: along the front, and just behind it.
Its big leaves read as a bold carpet where ordinary bugleweed is only texture. It covers ground quickly under shrubs and stays dark all winter in mild areas. Give it air: crowded plants rot in humid summers.
- Fast groundcover under shrubs
- Bold dark foliage at the front
- Spring colour with bulbs
What to plant with bugleweed 'Catlin's Giant'

- Lady fern: its green leaves are a setting for the flowers, before and after; fine leaves against its bold ones; tall enough (2½ ft) to stand behind it.
- Daffodil: blue against orange, opposite each other on the colour wheel, if you choose those colours, in flower together for two weeks; fine leaves against its bold ones; tall enough (16 in) to stand behind it.

When does bugleweed 'Catlin's Giant' flower in my zone?
In zone 5 it flowers early May to late 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 | Mid May to mid June |
|---|---|
| Zone 4 | Early May to early June |
| Zone 5 | Early May to late May |
| Zone 6 | Late April to late May |
| Zone 7 | Mid April to mid May |
| Zone 8 | Mid April to early May |
| Zone 9 | Early April to early May |
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 bugleweed 'Catlin's Giant' be planted?
18 in (45 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 24 in (60 cm), so a group knits into one patch.
It grows 8 in (20 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many bugleweed 'Catlin's Giant' plants do I need?
At 18 in apart, set out in staggered rows:
- 5 to fill 10 square feet (about 1 m²)
- 7 for a single row 10 ft (3 m) long
- 17 to fill a 4 × 8 ft bed on its own
In a mixed border, plant it as threes and fives, along the front and just behind it.
In the bed above, the planner used nine in three groups.
Is bugleweed 'Catlin's Giant' 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.
Is there a native plant like bugleweed 'Catlin's Giant'?
Bugleweed 'Catlin's Giant' comes from Europe, northern Africa, southwestern Asia. These North American natives come closest to doing its job:
- Creeping woodland phlox: the same job in a bed, the same flowering time and the same colour; 6 in narrower, medium leaves, not bold.
- Robin's plantain 'Lynnhaven Carpet': the same job in a bed and the same flowering time; 6 in narrower, lavender, not blue.
Matched the way the planner's Swap button matches plants: the same job in a bed, then size, then flowering time.
Do deer eat bugleweed 'Catlin's Giant'?
Mostly not. NC State lists it as resistant to deer and rabbits. No plant is proof against a hungry deer in a hard winter, but this one is low on the menu.
Will bugleweed 'Catlin's Giant' spread?
It spreads sideways, by runners or roots; the risk of it taking over is moderate. Spreads quickly by runners and will move into a lawn. Edge it yearly and thin crowded patches.
What flowers after bugleweed 'Catlin's Giant'?
Bugleweed 'Catlin's Giant' is over by late May. These start as it finishes and carry the same spot on, so it never goes flat:
- Lady's mantle: from late May to early July, 18 in tall.
- Astilbe: from late June to mid July, 24 in tall.
- Carpathian bellflower 'Blue Clips': from late June to late August, 8 in tall.
