These are one of my favorites! They are very similar to the annual Violas but grow every year. The flowers appear during spring and summer and sometimes even into the autumn. They are sweetly scented.
Colors of perennial Violas range from blue, speckled blue and white, yellow, white and even black! These easy perennials are great in flower beds, rockeries and in containers or window-boxes.
Centaurea montana - Perennial Cornflower
This pretty blue flowering perennial grows about 50 cm high and wide. The flowers appear in late spring and summer and attract beneficial insects to your garden. The silvery-green foliage is deciduous.
Centaurea deals very well with seaside conditions. Plant them in a sunny position and well-drained soil.
Erysimum 'Bowles Mauve' - Shrubby Wallflower
This incredible plant flowers nearly all year round if you plant it in a sunny spot. The purple flowers appear from early spring until late autumn. The silvery blue-green foliage is evergreen and forms a small bushy plant that deals well with coastal conditions.
The slightly scented flowers attract beneficial insects. Trim the bush lightly after the flowers have finished to keep the plant bushy and compact.
Erysimums are suitable for flower or gravel beds, rockeries, and containers.
If you have a spot in your garden where the soil is boggy and wet and you just can't grow anything there, try some Astilbes! This colorful perennial flower deals with boggy and wet soil conditions very well. Size varies depending on variety between 50-75 cm height and width.
Astilbes are available in pink, white or red colors. The foliage is either green or dark and shiny. Astilbes are deciduous and lose all their foliage in the winter. This is also a good plant for seaside gardens.
Sedums like a well-drained soil and a sunny spot. The red or pink flowers appear in late summer and attract lots of bees and butterflies.
The succulent-like leaves are silvery green. Some cultivars of these easy perennials have dark red foliage - very attractive! These flowering perennial plants cope well with poor dry soils and seaside conditions.
Alstroemeria - Peruvian Lily
Alstroemerias are beautiful clump-forming perennials and flower during summer and autumn. There are lots of different cultivars that vary greatly in size and flower color. The larger varieties grow up to 1 m high, compact forms up 40 cm.
If you want to grow Alstroemerias in a container choose one of the compact forms. Peruvian Lilies can have pink, red, orange, yellow or white flowers that are also great cut flowers.
Lilium - Lily Bulbs
Lilies can be grown in containers or flower beds with good soil and drainage. They produce magnificent flowers during the summer. Most Lily varieties have strongly scented flowers. You can get them in pink, yellow, red or white. Height also varies with the variety.
Choose the more compact forms for containers and windy places. They deal surprisingly well with seaside conditions though. Lilies are deciduous and die back for the winter.
