Seaside gardens are usually located in areas of milder temperate climates, where gardeners often don't have to worry about the hardiness of plants in withstanding cold temperatures. But when selecting plants for a seaside garden, factors, such as soil needs, wind and drought tolerance and tolerance to salt, should be considered.
Hydrangea is a deciduous shrub that produces large, globe-like masses of flowers in rich colors in shades of white, pink, blue or red. It can reach almost 8 feet in height. Plant in moist, well-drained soil, in sun to partial shade in a location protected from the wind. It flowers from mid to late summer.
Convolvulus Cneorum or Silverbush
Convolvulus Cneorum or Silverbush leaves are covered with a silvery fuzz. The tropical plant, also called bush morning glory, does well in drought conditions and in sandy or rocky soil. It produces pink buds and white funnel-shaped flowers during spring and summer. Plant silverbush in full sun or light shade.
Anemone Hupehensis vS. Japonica or Windflower
The Windflower is one of the taller anemone species, growing to almost 4 feet in height. The plant blooms from midsummer to fall. Colors include lavender and rose-pink flowers with semi-double petals and yellow centers. This works well in a seaside garden because it will grow in poor or rocky soil and salt tolerant. However, it does need protection from the wind. The anemone thrives in sun or partial shade.
Phyllostachys Nigra or Black Bamboo
Black bamboo is a perennial that is native to China. The plant has black bark and abundant green foliage. It grows to 15 feet. Plant in a seaside garden to use as a screen and offer protection from the wind to other plants. This plant does well in both sun and shade, and will grow in sandy soil.
