It can be grown outdoors in frost-free areas or grown indoors as a houseplant. Even indoors, bird of paradise needs daytime temperatures around 66 to 70 degrees Fahrenheit and at least 50 degrees at night.

Carnations are one of the longest-lasting cut flowers. They are also easy to grow from seed and have a wonderful clove-like fragrance. Although they are most commonly thought of as flowering in white, pink, and red, horticulturalists continue to develop new varieties in different hues. If you grow your own, you can have cut flowers well into fall.

Carnations will last in a vase for 7 to 21 days.

USDA Hardiness Zones: 5–9; grown as annuals in other zones

Color Varieties: Yellow, pink, red, white, magenta, coral, bicolors

Sun Exposure: Full sunSoil Needs: Evenly moist, well-drained

Chinese Lantern (Physalis alkekengi)

This relative of tomatillos and ground cherries is grown for the papery, bright orange husk that develops around its berries (which are toxic).1 The bright orange seed pods can be used fresh in arrangements. If allowed to dry, they'll keep for months, and maybe years. However, be aware that Chinese lantern can become very invasive. It spreads aggressively through underground rhizomes and It will self-seed prolifically if not deadheaded. It might be wise to grow this plant in a container where you can control its spread.

USDA Hardiness Zones: 3–9

Color Varieties: White flowers covered by orange calyx

Sun Exposure: Full sun to part shade

Soil Needs: Evenly moist, well-drained

Delphinium (Delphinium x elatum)

You can't beat delphiniums for shades of blue and purple, although they also come in white and pink. They can be difficult to grow because they like cool, moist summers. Delphiniums don't grow well in hot and humid climates. If you can grow your own, cutting the flower stalks as soon as they bloom will encourage the plant to repeat-flower. Like Peruvian lily, delphiniums are sensitive to ethylene gas so don't store in the refrigerator with fruits and vegetables.

Delphiniums will last in a vase for 7 to 14 days when cut fresh.

USDA Hardiness Zones: 3–7

Color Varieties: Blue, purple, white, pink, violet

Sun Exposure: Full sun

Soil Needs: Medium moisture, humusy, well-drained

Gladiolus (Gladiolus × hortulanus)

Gladiolus are among the most popular summer bulbs to grow. They can reach heights of four to six feet with their tall, spiky flower stalks. Gladiojus are thirsty cut flowers, so keep an eye on the water level and refill when necessary. You can force unopened buds to open by using warm water in the vase and covering the flowers with a clear plastic bag.

Gladiola flowers last seven to ten days when cut fresh and placed in a vase.

USDA Hardiness Zones: 6–10

Color Varieties: White, cream, yellow, orange, red, pink, green, lavender, purple, bicolors

Heather (Calluna vulgaris) gaffera/Getty Images

Sprays of heather are often used as airy filler in floral arrangements. They have long stems of small pink, purple, or white flowers. Another option for the vase is the very similar-looking heath plant (Erica spp.) These evergreens are very long-lasting when cut. Be ware that mold can occur if the stems are packed too tightly in the vase.

Cut heather will keep in a vase for one to two weeks.

USDA Hardiness Zones: 4–6

Color Varieties: Rose pink to purplish pink

Sun Exposure: Full sun to part shade

Soil Needs: Moist, well-drained, humusy; tolerates poor, sandy, or gravely soils

English Lavender (Lavandula angustifolia) Flottmynd/Getty Images

It is common to dry lavender, but it also makes a wonderful fresh cut flower. If you arrange fresh lavender stems without adding water to the vase, it will dry on its own and extend its vase life indefinitely. Lavender's strong fragrance intensifies as it dries. When arranging it in a water-filled vase, remove all leaves below the water level or they will rot.

Cut fresh and placed in water, English lavender will last for up to ten days.

USDA Hardiness Zones: 5–8

Color Varieties: many shades of blue and purple

Sun Exposure: Full sun

Soil Needs: Dry to medium moisture, well-drained

You can display any lily, but oriental lilies have the best fragrance. A bouquet of fresh oriental lilies can perfume an entire room. Choose sprays with a few slightly opened lower buds to prolong the bloom time in the vase. The stamens can drop pollen on anything that comes near them, causing an orange-yellow stain that is very difficult to clean from clothing. Use garden snips to remove the stamens by hand before cutting and arranging lilies in a vase

Cut lilies will keep in a vase for 7 to 14 days.

USDA Hardiness Zones: 3–9

Color Varieties: White, pink, red, orange, yellow, lavender, purple, bicolors

Sun Exposure: Full sun

Long-stemmed roses are favored by the florist industry, but you can grow and cut any type of rose for floral arrangements.

Sunflowers (Helianthus annuus)LOVE_LIFE/Getty Images

Homegrown sunflowers spend the early part of the summer growing tall and don't generally bloom until later in the season. You can find them at almost any time of year at flower shops because they have been imported from other countries. The traditional sunflower has bold, yellow flowers, but there are many new hybrids in shades of red and bronze. Sunflowers can be top-heavy, so use a vase that is sturdy enough to support them.

Sunflowers will last in a vase from 6 to 12 days.
