The Month-By-Month Alba Garden

I have noticed that many of my recent landscape designs are definitely leaning towards an alba garden palette, with customers asking for white-flowering plants, cream variegation, and some silver foliage highlights. This design theme came to prominence in the 1930s with the creation of the ‘white garden’ at Sissinghurst by Vita Sackville-West. She in turn was heavily influenced by the work of garden designer Gertrude Jekyll who pioneered the mass planting of perennials with solitary or similar hues, including the alba garden. So, I thought I would inspire you with a month-by-month revue of just some of the white-flowering or silver-hued perennials, shrubs, and trees at your disposal.


We start the season with what some gardeners consider a harbinger of spring, the pure white blossoms of Snowdrops or Galanthus nivalis. This species naturalizes very well and is usually purchased as a bulb in the fall, although forced plants are occasionally available. Bulbs should be planted as soon as possible, as they tend to dry out quickly and if a fellow gardener offers you some of their established Snowdrops, just lift clumps with greens in March and move them in place.

Joining it is the very hardy (zone 5) Erica carnea ‘Springwood White’ which often blooms from December to April with pristine flowers held over deep green foliage that matures at about 6” tall.


Next on our list is the Korean native Abeliophyllum distichum or White Forsythia. This hard-to-find deciduous plant bears fragrant blossoms from late February through April on a rather unruly 5’ tall shrub. It makes up for this by budding all along the stem and being an excellent cut flower.

Its companion is the shade-loving hardy Cyclamen coum, which flowers primarily from February to March. They have rounded silver-dollar-sized leaves (many with silver highlights) and are often sold in mixed flats, with the flowers ranging from near-white to deep magenta pink. The ‘whites’ are the most popular, so shop early before they get picked over.


Few Lily-of-the-Valley shrubs have as large pure white panicles as Pieris japonica ‘Snowdrift’. These emerge from pink buds in March and have a nice fragrance on warmer days. Expect an evergreen shrub that matures at 4-5’ tall and prefers a part sun exposure.

Another plant known for its fragrance is the Star Magnolia and the pure white Magnolia stellata ‘Royal Star’ doesn’t disappoint. It blooms before the leaves emerge from pussy-willow-like buds on a small tree that can actually be trained to bush form.


Witch Alder (Fothergilla major) is a relatively unknown member of the Witch Hazel family that bears honey-scented white bottlebrush flowers from April to May. It prefers a part- to full-sun exposure and also features fiery autumn foliage.

Azalea ‘Hino White Dwarf’ is much better known, as this compact evergreen shrub (2’ tall) literally smothers itself in pure white blossoms that are hard to miss in any garden.


With so much in bloom in May, it’s hard to choose just two but the old-fashioned Snowball bush or Viburnum opulus ‘Roseum’ is always a showstopper. This large deciduous shrub (10’ + tall) bears 3” wide spherical snowball flowers at this time and given its hardiness (zone 3), it is rarely affected by a cold winter.

My companion tree is the very showy Dogwood, Cornus kousa var. chinensis, which covers itself in starry bracts from top to bottom from May into June.
