Questions about yellow archangel 'Hermann's Pride'

Does yellow archangel 'Hermann's Pride' need sun or shade?

Yellow archangel 'Hermann's Pride' grows in 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 is one of the few that also put up with deep shade.

It wants ordinary well-drained soil, of average fertility, and a good soak in dry spells. Once settled in, it stands drought.

What zones does yellow archangel 'Hermann's Pride' 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 yellow archangel 'Hermann's Pride' flower in my zone?

In zone 5 it flowers early May to early June. As a spring flower it moves about a week for every zone: earlier where it is warmer, later where it is colder.

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 yellow archangel 'Hermann's Pride' be planted?

18 in (45 cm) apart, from the middle of one plant to the middle of the next. That is about its full width, so each plant keeps its own outline.

It grows 14 in (35 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.

How many yellow archangel 'Hermann's Pride' 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 a group of three or five, with a second group further along in the other number.

Is yellow archangel 'Hermann's Pride' 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.

What can I plant instead of yellow archangel 'Hermann's Pride'?

• Jacob's ladder 'Stairway to Heaven': the same job in a bed, the same size and the same flowering time; blue, not yellow, fine leaves, not medium.
