Japanese Kerria ‘Pleniflora’ is a cheerful, deciduous shrub noted for its bright yellow, double-petaled blooms that appear in late spring and may rebloom sporadically throughout summer. Its arching green stems remain attractive even in winter, adding year-round visual interest to the landscape.
Hardy in USDA zones 4 through 9, this shrub thrives in full sun to partial shade and well-drained soil. While it prefers some protection from harsh afternoon sun in hotter regions, it is otherwise tolerant of a variety of growing conditions, including drought once established.
Pruning immediately after the main bloom encourages a second wave of flowers and keeps the plant well-shaped. Japanese Kerria spreads by suckers, so occasional thinning may be necessary to control its size. It’s an excellent choice for woodland edges, cottage gardens, or informal hedges.
Rock Rose (Cistus spp.)
Rock Rose is a drought-tolerant evergreen shrub appreciated for its delicate, papery flowers that bloom profusely in early summer and continue sporadically through the season. Flowers appear in shades of pink, white, or lavender, each lasting only a day, but blooming continuously on new growth. The gray-green foliage adds texture and is resistant to deer.
Best suited to USDA zones 8 through 10, Rock Rose thrives in full sun and poor, rocky, or sandy soils with excellent drainage. It’s commonly used in Mediterranean-style gardens or xeriscapes due to its heat and drought resistance.
Little maintenance is required beyond occasional pruning to shape the plant after flowering. Overwatering or heavy soils can cause root rot, so it’s best planted in elevated or well-drained spots. Rock Rose makes a beautiful, easy-care addition to dry gardens or slopes.
Indian Hawthorn (Rhaphiolepis indica)
Indian Hawthorn is an evergreen shrub prized for its tidy, rounded form and clusters of fragrant pink or white flowers that bloom in spring and often reappear sporadically through summer. Its dark green, leathery leaves provide year-round appeal, and blue-black berries attract birds in the fall.
It grows well in USDA zones 8 through 11, preferring full sun to partial shade and well-drained soils. Indian Hawthorn is highly tolerant of salt spray, drought, and urban pollution, making it a popular choice for coastal gardens, foundations, and low hedges.
Indian Hawthorn needs minimal pruning to maintain shape and blooms best with ample sunlight. Watering is moderate once established, and it benefits from mulching and light fertilization in early spring. Disease-resistant cultivars are recommended to avoid fungal issues in humid climates.
Flowering Quince (Chaenomeles spp.)
Flowering Quince is a deciduous shrub known for its early spring blooms in vivid shades of red, pink, orange, or white, and select cultivars such as ‘Double Take’ may rebloom lightly during summer. Its thorny branches and dense growth make it an excellent barrier or hedge plant, while the showy blooms provide a burst of seasonal color.
It grows well in USDA zones 5 through 9 and prefers full sun to partial shade. Flowering Quince is adaptable to a variety of soils, including clay, as long as there is good drainage. Once established, it is drought-tolerant and resistant to deer.
Minimal care is needed beyond light pruning after the main spring bloom to encourage summer rebloom and control size. Some varieties produce small, edible fruits in fall. This shrub’s resilience and ornamental value make it a versatile choice for low-maintenance gardens.
Bottlebrush (Callistemon spp.)
Bottlebrush shrubs are striking ornamental plants named for their cylindrical, brush-like flowers that resemble bottle cleaners. These vivid red, crimson, or pink flower spikes bloom from late spring through summer and occasionally into fall, attracting hummingbirds and pollinators. The evergreen foliage is narrow and aromatic, adding visual and sensory appeal.
Native to Australia, Bottlebrush thrives in USDA zones 8 through 11, where winters are mild. It grows best in full sun and well-drained soil, and it tolerates drought once established. It can be grown as a shrub or trained into a small tree depending on the species and pruning practices.
To maintain shape and encourage repeat blooms, light pruning after flowering is recommended. Avoid overwatering, especially in humid regions, as it prefers slightly dry conditions. Bottlebrush is a standout choice for Mediterranean gardens, coastal landscapes, and pollinator-friendly borders.
Bush Cinquefoil (Dasiphora fruticosa)
Bush Cinquefoil is a compact deciduous shrub known for its cheerful, buttercup-like flowers that appear in shades of yellow, white, pink, or orange. These blooms persist from late spring through the entire summer and sometimes into early fall, making it a valuable long-season bloomer. Its fine-textured, dark green foliage adds to its charm.
It grows well in USDA zones 2 through 7 and is highly tolerant of cold climates. Bush Cinquefoil thrives in full sun and prefers well-drained soils, including sandy or rocky types. It is often used in mass plantings, borders, and low-maintenance landscapes due to its toughness.
This shrub requires little care beyond occasional pruning to maintain a neat shape and promote fresh blooms. Drought-tolerant and deer-resistant, it is ideal for gardeners seeking a resilient flowering shrub with reliable performance throughout the growing season.
Bush Morning Glory (Ipomoea carnea)
Bush Morning Glory is a fast-growing semi-woody shrub that produces large, trumpet-shaped, lavender-pink blooms throughout the summer. Unlike its vining cousins, this species forms a rounded, bushy habit and adds a tropical flair with its lush foliage and prolific flowering.
This plant grows best in USDA zones 8 through 11, thriving in full sun and moist, well-drained soil. It can be grown as a perennial in frost-free areas or treated as an annual in colder climates. It prefers warm, sunny locations and is often used for screening or background planting.
To keep Bush Morning Glory healthy and floriferous, provide regular watering during dry periods and prune lightly to encourage denser growth. It’s important to note that while beautiful, it can spread quickly in some regions and may need to be managed to prevent invasiveness.
Chaste Tree (Vitex agnus-castus)
Chaste Tree, often grown as a large shrub or small multi-stemmed tree, is valued for its aromatic foliage and spiky clusters of violet-blue, pink, or white flowers that bloom from early summer through late summer. These blooms attract butterflies, bees, and hummingbirds, making it a pollinator favorite.
