Geranium clarkei 'Kashmir White'


Care must be taken when adding white-flowered perennials to the garden. You may well end up with a different effect from the one you intended. Shades range from the stark, jarring white of perennials such as Shasta Daisy to more muted, creamy tones of many other perennials. Combine the white-flowered perennials below with plants recommended and your garden will reward you with enhanced beauty.

    Towering Hollyhocks, from 3 to 7 feet, produce single or double flowers with crinkled petals, opening from the bottom to the top. They are easily propagated by seed sown in fall where you want then to grow. Plants may bloom the first year but are actually biennials, producing foliage the first year and flowers the second.

              • AQUILEGIA

                Taylor's Guide to Growing North America's Favorite Plants has this to say about the Columbines. "The word "columbine" is from the Latin columbinus, meaning "like a dove", or columba meaning "dove". When looked at from above, the petals of short-spurred types resemble doves with their tails in the air, hence the common names doves-in-a-ring and doves-round-a-dish.".

              • ARABIS

                Rock Cress is a wonderful and easy alpine plant, perfect for spilling over rock edges. Its thick gray-green foliage is smothered in spring with small flowers that are sweetly scented. Like most alpines, it does best in well-drained, gritty soil in full sun.

                Arabis caucasica 'Flore Plena':  Rock Cress

              • ARENARIA

                Another easy alpine plant, Sandwort also requires good drainage and full sun, perfect for a sunny rock garden with neutral to slightly acidic soil. This is a diminutive perennial, growing only 2-4" tall. Leaves are narrow and form a low cushion covered in spring with starry 5-petalled blooms.

                Most Artemisias, or Wormwoods, are grown for their aromatic, shrubby foliage as their flowers are small and insignificant. Not so for those described below. Try them and enjoy their late summer creamy-white flowers held high above their bright green leaves.

                          • ARUNCUS

                            For its 4-6 foot height and spread alone, Goatsbeard deserves a featured position at the rear of your perennial border. For positions further forward you might want to try one of the shorter-statured forms. Foliage is light green and feathery off-white florets appear above to dominate the early summer garden.

                            This meadow favourite is known by many common names including Chigger Flower, Indian Paintbrush, Pleurisy Root and Tuberroot as well as Butterfly Weed. Its fragrant flowers will draw butterflies to your garden during summer. Attractive seedpods will form after blooming ends. For long-lasting arrangements, the stems should be seared after cutting, before being put into water. Bonus - Butterfly Weed is a host plant for the Monarch butterfly and supplies nectar for many other butterfly species as well.

                            Flowering in panicles or spikes, the Astilbe has numerous forms for every situation - from rockeries to perennial border specimens. Appreciating an annual mulch in spring with well-rotted compost, most forms, including the white forms below, grow best in partial shade.

                          • ASTRANTIA

                            Masterwort has interesting starry flowers surrounded by sharp bracts. Although this genus prefers moist shady borders it is adaptable to other sites. Different species provide varying colour choices, including pinks, reds, whites and greenish-white. Because it self-seeds, you will soon have a lovely patch to invite visitors' comments.

                            Astrantia major:  Masterwort, 30"x18"

                              Astrantia major - Masterwort

                                    Gray-green foliage and spikes of pea-like flowers cover the shrub-like 3-4 foot tall Plains False Indigo, also known as Blue False Indigo by early summer. Best in a sunny location as well as in well-drained, humusy soil a little on the acidic side.

                                    Baptisia alba:  white Wild Indigo

                                    Another vigorous perennial, Heartleaf Bergenia produces spires of mid-spring blooms. But it is the foliage that predominates. Huge, glossy, leathery leaves are evergreen, taking on reddish tones in fall and winter. Preferring moist well-drained soil with plenty of humus-rich organic matter, it tolerates some drought once established. Plant in groups for best effect.

                                    Bergenia 'Bressingham White':  white Bergenia, snowy white fading to pink

                                        I've never grown Boltonia, mainly because I'm not partial to white flowers. But if I wanted masses of aster-like flowers on a tall plant in late summer to early fall, this would probably be what I'd choose. Growing from 3-5 feet tall, it looks best planted in masses in well-drained, humusy soil in sun to light shade. Put it in a mid to rear border position and keep it moist.

                                        Boltonia asteroides 'Snowbank':  white Boltonia

                                            Are you looking for a short-statured 18 inch tall mid-summer to fall blooming perennial with clouds of dainty flowers and aromatic leaves. Try the Lesser Calamint in well-drained soil in full sun to light shade. Another good edger in the border or rock garden.

                                            Short or tall, well-behaved or invasive, the Bellflowers have a number of white forms in addition to the mainly purple ones I tend to go for first. They prefer lots of organic matter mixed into their planting site. Good drainage and even moisture will encourage their best performance.

                                                          Much reclassification has taken place in the genus Chrysanthemum. The references below use the original names with new names beneath for clarity. My references say that plants reclassified as Leucanthemum are the one which deer do not normally eat, and that butterflies are especially attracted to those reclassified as Tanacetum. Check out which ones that includes in the current names below.

Just when I was ready to give up on the self-sown seedlings I found and moved to the rear of a relatively new shady bed. The divided foliage looks lovely and continues to clump up nicely. Hopefully its lovely white spires of bloom will tower over the mid-border plants in front this year or next. According to the American Horticultural Society FLOWER FINDER these are among the very best and most maintenance-free perennials - almost completely pest and disease free. Well worth waiting for.

With a possible height to 6 feet and a spread as wide as 5 feet this is one perennial that demands space. Fragrant airy flowers appear in a cloud above huge, bold, dark green leaves. Best in full sun to very light shade and rich, moist, well-drained soil.

They are superb at the rear of a garden bed where the stakes required by the tallest forms will be hidden behind other plants as well as by the delphinium's own foliage. Perform this chore early before the flower spikes begin to bow over from lack of support.

The dark green foliage is coarse but sets off the white ray-like flowers with the lovely bronzey-orange cone-like centres to perfection. Very long-blooming, if kept dead-headed, they deserve a prominent place in every border. Bonus - they attract both butterflies and bees. And, for me, they've repeatedly self-sown so my collection keeps growing.

Tuberous roots should be planted in fall in a hole 4-6 inches deep and 2 feet across. Well-drained, light, fertile soil is best. Drought-tolerant once established, it has forms of varying heights. Foliage dies back after bloom has finished so hide this perennial, wonderful when mass planted, at the rear of your border.

Dainty, white flowers appear in spring in layers along the stems. Growing only 6 to 12 inches high, it is a drought-tolerant groundcover that does well even in the dry shade of the cedar trees over our garden beds when other plants are drooping in the heat.

First - after their spring to early-summer bloom is over you can cut the foliage back hard and encourage new fresh foliage to appear. Second - they are the perfect companion, planted in front of other perennials that bloom during the time the geranium's foliage is undergoing regrowth. Third - they come in so many colours and sizes that there are choices for every situation. Give them full sun with humusy, well-drained, evenly moist soil and enjoy the show they put on. And keep them well watered during dry spells.

The many different species of Coral Bells often have a number of white-flowered choices. The mound-shaped foliage serves as a base from which erect stems arise, with panicles of dainty flowers held high above. Cut back to the base of the stems to encourage more blooms to appear.
