What are the easy sun perennials?
These include peonies, iris, clematis, candytuft and dianthus. Next come summer-bloomers such as bee balm, echinacea, daylilies, liatris, yarrow and phlox. The last perennials of the season include sedum, rudbeckia, asters, kniphofia, mums, russian sage and helenium. Top choices include geranium rozanne, one of the longest flowering perennials, and erigeron karvinskianushelle, which fills gaps and spills softly over edges. Helleborus orientalis brings early colour in winter, while echinacea magnus and rudbeckia goldsturm offer bright summer blooms with almost no care required.Some of the best include Geranium Rozanne, famous for its incredibly long flowering season, and Salvia Caradonna, which blooms early and often. Gaura Whirling Butterflies, Verbena bonariensis, Scabiosa Butterfly Blue and Nepeta Six Hills Giant also flower for much of the summer.In general, daylilies are a great perennial addition, but the Stella de Oro’s are some of the earliest and longest blooming varieties. Coneflowers or echinacea have perennial flowers that bloom through summer in pink, purple, white, orange, red, or yellow.Sun loving coleus and bronze leafed wax begonias may work. Just keep the soil moist. Purple Heart (Setcreasea purpurea), pentas, and four o’clocks are other annuals to consider. For perennials try dwarf Mexican petunia (Ruellia), lilyturf, daylilies, and speedwell (Veronica).
What is a late flowering perennial?
Late flowering perennials keep the garden blooming through the autumn, right up to the first frost, extending the season of colour when many summer flowers are starting to fade. Late perennials are a must-have for every mixed border and flower bed and combine well with wispy grasses. The best times for planting perennial flowers are during the spring and fall. Planting during these seasons will ensure your plants grow healthy and strong. In the spring, you have warmer soil, plenty of rainfall, and longer days with more sunlight.If the plant is described as ‘Hardy Perennial’ it should stand up to average low winter temperatures and come up each year for several years. A ‘Hardy Biennial’ will build up a strong root and leaf system in its first year, survive the average winter and go on to flower, set seed and die off in its second year.
