Keep Flowering Perennials Blooming From Spring Until Fall
Garden in Bloom
Plant a Variety of Flowers That Bloom at Different Times
Your garden can bloom from early spring until late fall if you plant a variety of flowers that bloom at different times. Some early flowers will even bloom in the snow! And in a sheltered, sunny spot, late flowers can bloom until Thanksgiving. I've had roses and snap dragons (an annual) in late November.
If you stick to bulbs and perennials, you won't have to worry about buying a lot of new plants every year. Bulbs and perennials come back year after year, and usually spread and can be divided, so are worth the investment.
Some of the flowers that I have suggested are actually bi-annuals, which means that they set out foliage one year and flower the next. If you plant several, and allow them to self-seed, you can keep them blooming every year. Several plants mean that bi-annuals can take turns blooming.
Many flowers can be dead-headed to encourage repeat blooming. Once the flower has died, cut the stem back to just above the next full set of leaves.
Allow dead flower heads to remain on the stem in fall. Some will drop seeds. Others may attract birds.
- Turn and enrich your soil with compost before planting.
- A sprinkle of bone meal will encourage large, brilliantly colored flowers.
- Water new plants often and well. Water deeply to encourage root growth.
- Make sure you plant appropriately. Some plants need full sun while other prefer shade.
- Learn the pH of the soil in your area. Certain plants prefer an acid soil; others need slightly alkaline soil.
- Scatter plants that flower at the same time throughout the garden. Mix them all up for a better show.
- Plant tall flowers in the back, small ones in front for best viewing.
EARLY TO MID SPRING
Spring Flowering Bulbs - In Order of Appearance
Select the right combination of spring bulbs for a colorful display that lasts all season. There is nothing like that first glimpse of crocus after a dull winter.
Plant spring flowering bulbs in fall. The depth you plant bulbs depends on which type that you plant. Check plant tag for instructions.
If your neighborhood has experienced several cases of disappearing tulips, plant the bulbs a few inches deeper than suggested. In winter months, mice and voles tunnel under the ground, and will eat the bulbs.
For each bulb planted, add a tablespoon of bone meal at the bottom of the hole.
If you did not plant bulbs in fall, you can purchase tulips, daffodils, etc in bloom during springtime. Enjoy the flowers indoors, then plant outside after the flowers have faded to enjoy next year.
Star of Bethlehem - small, low growing white, star shaped flowers that spread. They can be invasive in some areas.
Crocus - come in a rainbow of colors. Some are striped! Plant in your lawn for a delightful spring surprise. (But when the lawn mover chops down the foliage, these lawn planted crocus will not come back next year)
Hyacinths are strongly scented flowers. Tiny, waxy flowers grow on a sturdy stem about 12" tall in white, purple, yellow, pink, and violet blue.
Daffodils are 1' - 2' tall with brilliant yellow trumpet shaped blooms.
Grape Hyacinths are low growing plants with grassy like foliage that can bloom from early to late spring. Tiny round flowers cluster in shades of purple, blue, or pale violet.
Narcissus come in a variety of colors and color combinations. Small cup shaped flower set in the center of a circle of petals that grow nearly 2' tall.
Tulips, the queen of spring flowers, bloom in mid spring, 1' - 2' tall in a wild variety of colors - red, white, peach, pink, yellow, purple and variegated combinations of colors including green.
Iris are tall, dramatic flowers that grow from either bulbs or rhizomes (which are divided and planted in July). 3' - 4' sturdy stems bear a large bloom framed with downward handing petals in almost any color that you can imagine. Long, sword shaped leaves take up a lot of room
OTHER SPRING BLOOMING PLANTS
Azaleas - woody shrubs that prefer some shade and provide a large splash of color. They prefer acid soil and lots of mulch and moisture. Water well during the summer months.
Rhododendron - woody shrubs that can be from 3' to 12' tall, brilliant flower clusters above shiny leaves. Bloom after the azaleas.
Bleeding heart is an old fashioned herbaceous plant with tiny heart shaped flowers. The beautiful foliage dies back in summer so you might want some fill-in plants. Up to 3' tall. After some years, Bleeding Heart becomes quite wide. Does not transplant well.
Late Spring/ Early Summer
