Geranium (Hardy Geranium or Crane’s Bill) ‘Brookside’

Geranium ‘Brookside’ is one of the best blue geraniums. This is one of the best introductions of the last ten years with a compact habit and long flowering. It begins flowering well before the end of May & throughout June and often persists right into September. The flowers are largish, cup-shaped, clustered, numerous, of a vibrant sapphire-blue, creamy white at the center. It is often said to be a true blue color better than its predecessor ‘Johnson’s Blue.’ It’s usually or almost a true blue color, although sometimes closer to a violet-shaded blue with darker faint veins. It likes full sun or part shade, moist well-draining average soil, and is hardy to minus 30 degrees F., suited to zones 4 through 9.

Noteworthy Characteristics: Geraniums were once considered the “must have” plant for English gardens and with over 400 species it wasn’t long before cultivars developed popularity with gardeners world wide. Buyers beware however as perennial geraniums are not related to annual geraniums which are actually in the genus Pelargonium. A true geranium is a cold hardy perennial that will prove to be long-lived and add years of beauty and graceful charm to any garden.

General Information +

Botanical: Geranium 'Brookside'

Common: Crane's Bill

Family: Geraniaceae

General Characteristics: The foliage of this Geranium retains its mound-like shape after flowering and has great fall color in shades of red and orange. The lacy deeply cut gray-green upright & mounding foliage is fairly heat-resistant & holds its looks in summer. It has rapid growth but is a slow spreader. It can eventually cover a two-foot stretch of ground very nicely, sufficiently compact to suppress weeds on the garden border. After a few years the clump may seem overlarge, but can be lifted & divided late winter or early spring.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. If it does get to tattered or worn looking, or if flowering seems to quit at mid-summer, a trimming & deep watering will refresh it & induce reflowering for early autumn.

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Easily grown in average, medium wet, well-drained soil in full sun to part shade. Tolerates some drought, but prefers and spreads best in moist, humusy soils with good drainage. Dead-heading is tedious for larger plantings and probably unnecessary. Spent stems may be removed at any time to control spread. If not dead-headed, some self-seeding may occur in ideal growing conditions. Foliage may decline after flowering in hot summer climates, at which point it may be lightly sheared back and shaped to revitalize.
