Marigold, cosmos, zinnias, sunflowers, morning glories, and nasturtiums, as well as sweet alyssum, celosia, cornflower or bachelor button, and nasturtiums. We planted some sunflower seeds outside, but they didn't sprout for two weeks, despite the fact that we had a few of unexpectedly chilly days during that period.

Sunflowers Sunflowers are not only extraordinarily fast-growing flowers that may grow up to six feet tall in three months, but they are also one of the easiest flowers to care for. When planted in rich soil with plenty of sunlight, sunflowers will produce seeds which will continue to bloom even after being cut from the stalk.
Nasturtiums Nasturtiums are easy-to-grow vegetables that add color to your garden. These plants produce clusters of trumpet-shaped flowers that appear in shades of red, orange, and yellow. The flowers have a spicy flavor that some people find off-putting but others love. For this reason, nasturtiums are often used as a vegetable marker or ground cover. They will spread by underground rhizomes and can be controlled by pulling them out when the first signs of bud decay appear.
Tulips Tulips are flowering plants that belong to the lily family. Like other members of this family, tulips are grown for their beautiful flowers. However, unlike most other flowers, tulip bulbs must be dug up before they can be planted again. This is because the bulb contains layers within its skin that absorb moisture from the soil if it is left in place after flowering. This could cause the plant to die down each time it rains.
Beginners should begin with perennial seeds that are easy to grow at home, such as black-eyed Susan (Rudbeckia), catmint (Nepeta), perennial geranium, centranthus, aster, purple coneflower (Echinacea), armeria, snow-in-summer (Cerastium), or yarrow (Achillea). These plants are all native to North America.
As you gain experience, you can try more challenging species such as Japanese knotweed (Polygonum cuspidatum), which is difficult to control and invasive. Don't attempt to grow large trees, such as oak or maple, from seed. They may not produce any seedlings at all. Instead, plant acorns in rich soil with some organic matter. In time, small trees will develop from the shells.
Some plants require assistance to reproduce their seeds. These include fruit trees, which must be pollinated by bees or other insects, and nut trees, which produce only male flowers that cannot self-pollinate. Fruit trees and nut trees are discussed separately here.
Fruit trees need to be pollinated by an insect for each flower to set a seed. Most commonly this is done by flying insects, but tree branches rubbing together, water spray, or natural weather events can also serve as pollination agents. If pollen from another tree of the same species is introduced into the flower, it will become fertilized and a fruit tree will grow from that seed.
Flowers That Grow in Any Climate
Other perennials that may blossom in their first year from seed include: Salvia bleue (Salvia nemorosa) Vervain americana (Verbena hastata) Susan with black eyes (Rudbeckia spp.) These plants should be started off in small pots on a sunny windowsill. When the seedlings reach about 12 inches high, they can be transplanted into the garden.
Salvias are attractive plants for cutting flowers. They will reseed themselves if left in place long enough. The new plants will look like salvias but will not have red berries when they mature. Instead, they will contain white or yellow seeds.
Verbenas and Rudbekias are attractive plants for cut flowers. The new plants will look like verbenas or rudbekias but will not have purple-blue berries when they mature.
Perennial herbs that may also bloom in their first year from seed include: Basil mint Thymus zenkeri (thyme) This plant should be started off in small pots on a sunny windowsill.
These are just some of the many perennials that can be started from seed.
