Question by dvd79

I am a newbie to gardening and recently planted 10 asiatic lilies about 12 inches apart for a border along a fenceline. I did not know they do not rebloom and most of them lost their flowers and I would like to plant a perennial in between them that is a long lasting bloom. Any suggestions??

Lily flowers are so spectacular that I forgive them for their short bloom period. When they do bloom, they are fantastic! Here are a few suggestions for long blooming perennials:

Campanula (Bellflower) Bloom Span: 2+ Months; There are many species of Campanula or Bellflowers, all easy to grow and relatively long lived. They perform best in areas with cooler summers or in partial shade where the summers are more intense. Most Bellflowers will readily self sow. If they start to look tired and ragged after several blooms, shear or mow them down to a few inches and they will grow back fresher.

Centranthus (Red Valerian) Bloom Span: 3-4 Months; Centranthus prefers dry, lean soil, but it blooms longer in cooler climates. In intense heat it will bloom in spring and again as it feels up to it, throughout the summer.

Coreopsis (Tickseed) Bloom Span: 3+ Months; Coreopsis are undemanding plants, but short lived. Either allow them to self-seed or divide the plants every 2-3 years and replant the newer, outer sections. Flower buds form all along the stems, making deadheading a time consuming challenge. Once the initial buds have completed blooming, sheer the plants back by 1/3 to encourage new flower buds.

Dicentra formosa & Dicentra eximia (Fringed Bleeding Heart) Bloom Span: 3+ Months
Unlike the common bleeding heart (D. spectabilis), cultivars of the fringed species will repeat bloom for most of the summer. D. formosa is a western native while D. eximia is able to handle the heat and humidity of the eastern U.S. The fringed bleeding hearts are smaller plants than D. spectabilis and the flower is not as pronounced a heart shape, but the gray-green ferny foliage and abundance of flowers make it a prize.

Echinacea purpurea (Coneflower) Bloom Span: 2-3 Months; Having a long bloom period is just on of Echinacea's many attributes. Coneflowers are extremely drought tolerant, attract birds and butterflies and the intense color adds punch to any garden. The tall stalks are self-supporting, unless they've received so much water they become floppy. They require good drainage and full sun. Deadheading will prolong the bloom period.

Gaillardia (Blanket Flower) Bloom Span: 3-4 Months; Gaillardia's yellow petals around a burgundy center are impossible to ignore in a garden. All they ask is full sun and they will keep on blooming all summer. Too much shade and the stems begin to flop. In most cases, deadheading is not necessary for continual bloom, but it can make the plants look tidier.

Liatris (Gayfeather, Blazing Star) Bloom Span: 3 Months; Liatris are easy to grow and texturally unusual. The thin, spiky leaves jut off the stems all the way to where the rosy-purple flower spikes begin. Unlike most spiky flowers, Liatris blooms from the top down. Liatris can handle just about any type of soil, but the richer the soil, the more likely they'll need staking. They'll grow in full sun or partial shade. Liatris is long lived and doesn't often require division. They will self-seed, but generally don't take over.

Nepeta (Catmint) Bloom Span: 2-3 Months; Most people think of Nepeta as catnip (Nepeta cataria), a somewhat weedy garden plant. But there are many excellent ornamental Nepetas that will bloom throughout the summer, if deadheaded. Most have some shade of blue-lavender flowers and gray foliage. They are very drought tolerant and make a nice substitute for lavender, in areas where lavender won't thrive. )

Rudbeckia (Black-eyed Susan) Bloom Span: 3 Months; Rudbeckia are at home everywhere and many are native to various parts of North America. They prefers well-drained, somewhat lean soil and full sun. Deadheading will prolong bloom and cut Rudbeckia flowers will last a long time in water. With their flat landing pad petals, they are attractive to butterflies and the seeds will be eaten by the birds during the winter.

Scabiosa (Pin Cushion Flower) Bloom Span: 3+ Months; Scabiosa is a unique looking plants with a low growing rosette of narrow leaves and a profusion of gangly stems topped by pincushion flowers. They are relatively easily grown in average soil and full sun. Deadheading is a must for long bloom and general appearance.

Hope these suggestions are helpful.
