Guides: Late Spring
Real eye-catchers in the garden, Gladiolus, also known as sword lilies, are cormous perennials boasting incredibly spectacular spikes of funnel-shaped flowers in summer in a surprisingly wide range of colors. Borne atop attractive fans of sword-shaped or linear leaves, they always provide a dramatic effect with their rich and cheerful colors and their breathtaking vertical lines.
Queens of the winter flowers, Camellias are attractive evergreen shrubs that are highly prized for the beauty of their exquisite blooms, their splendid evergreen foliage and their compact shapely habit. Blooming prodigiously for weeks from fall to spring (depending on climate and variety), when the rest of the garden offers little, Camellias are ranked as one of the very best flowering shrubs
While all Japanese Maples are beautiful and provide a fabulous architectural presence, in the garden or in containers, some enjoy particularly outstanding features such as dramatic foliage, long-lasting striking leaf color, unusual leaf shape or striking winter bark. The eye can never pass lightly over the dazzling color presented by their flaming foliage across seasons or the graceful outlines of their brilliant coral twigs and branches.
As climbers, Clematis are unsurpassed in their long flowering presence, their rich diversity of flower shapes, their wide array of colors and tolerances in terms of exposure and climate. Members of the Ranunculaceae family, Clematis include more than 300 species and hundreds of hybrids. They are divided into 12 groups.
The Large Flowering Amaryllis group is the most popular group with single flowers up to 8-10 in (20-25 cm). Their cultivars belong to the Galaxy group. Each bulb usually produces 2-3 stems and 4-6 flowers per stem. These exquisite Amaryllis tend to grow up to 18-24 in. tall (45-60 cm). Depending on temperature, they bloom 6-10 weeks after planting.
More and more popular, the Cybister Amaryllis are truly spectacular with their exotic, orchid-like flowers. They feature long, ribbon-like, spidery petals and splashes of bright color such as deep reds, soft green, copper, dark pink, creamy white and burgundy. They are unlike any other Amaryllis group and their cultivars belong to the Spider group.
Most gardeners are unaware of the wide range of characteristics offered by Malus species and their cultivars in terms of flower color, fragrance, fruit color, fruit retention, fall foliage, tree shape, and disease resistance. These are key elements to consider when selecting a flowering crabapple. Consequently, you should not eliminate varieties merely by flower color alone, or you may end up with a less than optimum tree with limited interest.
Prized for its delightful fragrance, Syringa vulgaris (Common Lilac) is a mainstay of the spring landscape in northern and colder climates. Easy to grow, tough as nails, deer resistant and relatively free from major pests, Common Lilacs are one of the most effective flowering shrubs. Tailored to meet the needs of all gardens, this species counts 2000 cultivars.
Appealing to most gardeners, Dicentra (Bleeding Heart) are rhizomatous or tuberous perennials with heart-shaped flowers dangling in arching panicles or racemes above attractively divided leaves. Shade tolerant, they bloom over a long season, extending from late spring to early fall, in cooler climates. In hotter climates, flowering will usually stop in the heat of the summer, but may start again when the weather cools in late summer or early fall. Beautiful in leaf as soon as they sprout, they quickly add their charming blooms and make elegant additions to the garden when combined with other shade-loving perennials.
Naturalizing bulbs is a terrific way to brighten up lawns. A surprisingly large number of perennial bulbs do well in grass, such as snowdrops (Galanthus), crocuses (Crocus), squills (Scilla), checkered lilies (Fritillaria meleagris) and plenty others charming bulbs. Left undisturbed in the ground, they will emerge again every spring, but will also gently multiply as long as they receive the right light conditions and are planted in soil with the proper drainage.
Naturalizing bulbs is a terrific way to brighten up lawns, prairies or meadows in spring. They also make gardening easy. Once planted, there is nothing left to do: these bulbs can stay right where they are and produce flowers year after year. What could be better?
The tall Alliums in particular are very impressive when towering up above lower-growing plants or ground covers. They are definitely displayed at their loveliest when placed among perennial plants in the border. Their leaves, which are usually not very attractive and which also wither back quickly after flowering, will then be hidden beneath the leaves of the perennial plants.
Tulips, daffodils, hyacinths and crocus: these are the spring bloomers everyone knows. But there are hundreds of other, lesser-known beauties to plant in fall. Some are small and delicate, others tall and ungainly. All are fabulous. Wait till you see them!
Native to Mexico and Central America, Echeverias are regarded by many as one of the most beautiful succulents. Evergreen, they form attractive rosettes of fleshy leaves and often resemble plum-petaled roses, waterlilies or ruffled lettuce. There are dozens of species, and hundreds of cultivars offering a wide array of colors, sizes or leaf shapes.
Robust and hardy, Ipheion (Spring Starflower) are small bulbous perennials with lovely star-shaped, sweet violet scented flowers borne on long slender scapes in mid to late spring. Blooming for up to 8 weeks, the dainty blossoms rise atop a cushion of narrow, pale, delicate and grass-like leaves. Regarded to be one of the easiest bulbs to grow
Native to North America, Camassias (Camas) are bulbous perennials with long racemes of up to 100 star-shaped flowers, adorned with six slender loose petals, a green center and bright yellow stamens. The flowers vary in color from pale lilac or white to deep purple or blue-violet. Borne on stout, willowy stems, they open sequentially from bottom to top for a long lasting display.
Tall and graceful, Siberian Irises (Iris sibirica) are among the most trouble-free and low maintenance perennials in the garden. The choice of available Siberian Iris cultivars varies from country to country, but a few of these beauties have won the prestigious Morgan Award, the highest award reserved exclusively for Siberian Irises within the American Iris Society.
A favorite of florists and gardeners, Hydrangeas are easy-care, long-lived, deciduous shrubs with magnificent flowers which show off in gardens, containers or in vases around our living areas.

Mostly native to the U.S. and Canada, Asclepias include over 100 species of evergreen or deciduous perennials adorned with clusters of small, interestingly shaped blooms that are irresistible to butterflies. Attractive and easy to grow, they shine in many perennial gardens and are a key component of butterfly gardens, cottage gardens, or prairies and meadows.
One of the most beloved of the spring woodland wildflowers, Trilliums (Wake Robin) are remarkable rhizomatous perennials with unbranched stems, noted for the perfect symmetry of their leaves, petals and sepals which all come in groups of three, hence the genus name. Their blooms can be either showy or discrete, their foliage handsomely mottled. Jewels of the shade garden, they are fully hardy and will blossom and blend beautifully with other woodland plants.
A member of the Hyacinth family, Ornithogalum (Star of Bethlehem) are bulbous perennials grown for their clusters of typically star-shaped, white flowers in spring or summer, depending on the species. They quickly form large clumps of grassy or strap-like leaves.
A member of the Lily family, Erythronium (Dog Tooth Violet) are charming bulbous perennials grown for their nodding, lily-shaped flowers adorned with gracefully reflexed petals in spring. Equally attractive is their foliage of elliptic leaves, often copiously marbled with purple-bronze.
