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.

A 12 × 6 ft (3.7 × 1.8 m) bed at eye level in mid May: Bugleweed 'Catlin's Giant', Dwarf lady's mantle, Foxglove, Inkberry 'Gem Box', Northern sea oats, Glory-of-the-snow, Giant snowdrop.

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'

Plants recorded as good partners for it, and what each pairing does:

  • Hosta: its green leaves are a setting for the flowers, before and after; a low mound at the foot of its spires; tall enough (18 in) to stand behind it.
  • 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.

Questions about bugleweed 'Catlin's Giant'

Does bugleweed 'Catlin's Giant' need sun or shade?

Bugleweed 'Catlin's Giant' grows in part sun (4 to 6 hours of sun, including some afternoon sun), part shade (2 to 4 hours of sun, mostly in the morning) and shade (less than 2 hours of direct sun, or bright dappled light).

It wants ordinary well-drained soil, of average fertility, and a good soak in dry spells.

What zones does bugleweed 'Catlin's Giant' grow in?

USDA zones 3 to 9. It is hardy to zone 3, which means it survives winter nights down to about −30 °F (−34 °C).

Gardening in Canada? Use the USDA zone for your town: Canada's own zone map uses different numbers.

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.

Roughly when bugleweed 'Catlin's Giant' is in flower
Zone 3Mid May to mid June
Zone 4Early May to early June
Zone 5Early May to late May
Zone 6Late April to late May
Zone 7Mid April to mid May
Zone 8Mid April to early May
Zone 9Early 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:

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:

What does bugleweed 'Catlin's Giant' look like in winter?

Bugleweed 'Catlin's Giant' holds some of its leaves into winter, more in a mild year or a sheltered spot, and they look tired by March. Cut the old ones off as new growth starts.

Is bugleweed 'Catlin's Giant' good for bees and butterflies?
