Kalmia latifolia (Mountain Laurel)

“Rarely, if ever before, have the Arboretum Laurels (Kalmia latifolia) been as full of flower buds as they are now. . . .The flowering of the Laurels is the last of the great Arboretum flower shows of the year, and none of those which precede it are more beautiful, for the Mountain Laurel is in the judgment of many flower-lovers the most beautiful of all North American shrubs or small trees.” Charles Sprague Sargent, Director of the Arnold Arboretum, Harvard University. June 1916.

“107 years later, I am watching the best mountain laurel bloom in my thirteen springs here.” William Ned Friedman, Director of the Arnold Arboretum, Harvard University. June, 2023.

I join Director Sargent’s celebration of our native shrubs and agree with Director Friedman that 2023 has been an especially splendid flowering year – one of the best floral displays in the 30 years Mountain Laurels have graced my Southampton, N.Y. garden. Apart from the standard pink and white flowering plants that were here when we bought the property, I have added a number of Richard Jaynes colorful hybrid cultivars. Photos below. (Jaynes is the foremost Mountain Laurel breeder and the founder of Broken Arrow Nursery in Conn.)

Note: While Jaynes hybrids have beautiful flowers, many of the early cultivars are vulnerable to foliage disease. My favorite shrub, ‘Carol,’ is the exception: In addition to showy bloom, it possesses healthy, glossy, dark-green leaves. (See the first photo above.) Recent Richard Jaynes introductions may have improved disease-resistance.

Mountain Laurels thrive in well-drained, organically rich, acid soil, in shade. Gardeners report that they also do well in sun. The shrubs bloom on new growth. For maximum flowering, remove faded flowers that retard foliage growth and the formation of new buds. Without gardener intervention, wild laurels only bloom every other year.

In May, Rhododendrons rule! My shrubs performed this year with awe-inspiring, massive colorful displays of exquisite bloom. They surely are A-List garden-worthy. Photos below.

Years ago, J.C. Raulston, revered horticulturist/educator, suggested a way to choose plants with the “highest garden merit”:

“I’ve decided,” he said, “they need to be basically tough and not need pampering with relatively low maintenance (little or no special environments, modified soils, watering, pruning, spraying, etc.), have interest or appeal over a fair length of time, [and] that they have high ornamental value at least at some point (showy or interesting flowers, fruit, foliage, texture, etc.)”

Please consider the following easy-care deciduous shrub — time-tested in my organic garden — which clearly passes the Raulston test:

Abelia mosanensis Z 5-9 (Hardy Abelia, Fragrant Abelia)

As they say in the movie business, this shrub has “legs.” First, in early Spring, it is blanketed by clusters of pink buds emerging from green calyxes. Then, in mid-May, the buds open to deliciously fragrant white flowers. Finally, when the flowers fade, the calyxes take center stage and this non-stop performer appears to be covered in lovely green flowers until frost. My plant has been disease-free and pest-free and flourishes in moist, acid, well-drained, organically rich soil. Photos below.

I recently purchased three amazing pollinator-favorites that are also, in my opinion, “highest garden merit” plants :

Buddleia x ‘Miss Ruby’ Z 5-9 (Butterfly Bush)

The English Royal Horticultural Society’s Popularity Poll ranked Miss Ruby number 1 out of 97 other Buddleia cultivars. No surprise. Its fragrant, vibrant red flowers bloom continuously from summer to frost and the plant is deer-resistant and rabbit-resistant. Moreover, Miss Ruby is beloved by butterflies and hummingbirds.

This beauty is not particular about soil pH but prefers well-drained soil in sun. (Note: Gardeners have reported that it flowers well in high shade and part shade.) Miss Ruby can be hard pruned in Spring because it flowers on new growth — even if it dies to the ground in winter.

Salvia nemorosa’ Pink Profusion’ Z 3-8

This re-blooming easy-care charmer has been chosen 2024 Proven Winners National Perennial of the Year. The plant is resistant to deer and rabbits and its fragrant, showy pink flowers attract butterflies, bees and hummingbirds. For re-bloom, prune after flowering. It is not particular about pH but requires well-drained soil.

Torenia ‘Purple Moon’ (Wishbone Flower)

It was love at first sight—I grabbed three Purple Moons as soon as we were introduced. But this annual is more than just a pretty face. The gorgeous, velvety flowers are produced in abundance from Spring to frost and attract bees and hummingbirds. Purple Moon is an ideal container spiller in shade or part shade.

I purchased the pollinator plants from Eastland Farms. Eastland has an extraordinary selection of plants and outstanding customer service. (Thank you, Courtney!)
