There are a ton of plants that fit into this category, including marigolds, dusty miller, ageratum, petunias, cleome, and nicotiana. The most spectacular (and popular) annuals are the tropical or exotic annuals like begonias and impatiens. Unfortunately, these are also the most tender type of annuals.

Cool season vegetables such as leaf lettuce, spinach, radishes and onion sets may be planted outdoors as soon as the soil is dry enough to work. Snapdragons, bachelor buttons and sweet pea seed can be planted outside in April as well.
Many times zinnias will bloom well into fall. Start the seeds in a good seed-starting mix under lights about 4 to 5 weeks before the last frost date. (As a general rule, Minnesotans can use May 15 — though up north it may be May 30.)
The best time to plant tulip bulbs in Minnesota is generally in early September, but the arrival of autumn frost varies in different parts of the state. Although you can plant tulip bulbs until the ground freezes, they’ll do better if you plant them early enough to grow some roots before the first hard frost.

If you prefer to start seeds indoors, most annuals and vegetables should be started between early March and mid-April in Minnesota.
Corn is the state’s most valuable crop followed by soybeans and again, Minnesota is a leading producer. Farmers also grow hay, sugar beets, wheat, barley, flaxseed and oats. The leading vegetable crops are peas, potatoes and sweet corn. Minnesota’s leading fruit crops are apples.
In the central to southern portions of the region, gardeners can expect a growing season from April to October. Gardeners in Michigan, North Dakota, Minnesota, and Wisconsin, however, have a much shorter growing season.
They may have gone wild but they aren‘t native. Here in Minnesota, I grow a patch of California poppies out front to remind me of my home state. … Those poppies are native to the Western U.S. but not to here.
Wait until after the last frost (mid-to-late May) before transplanting tomatoes, eggplants, peppers, summer squash, basil and similar “warm season” crops. Warm season crops need a long growing season. They will not mature if seeded directly in the garden.
Once they have adjusted, pansies are off to the races. They will flower profusely from planting time until the weather gets super hot. Last year, I planted pansies in my front-door container in April—a much warmer April than we are having this year—and left them there until July.
Cutting down the dead plant stems too early in the spring will disturb them before they have a chance to emerge. Wait as long as you can to do your spring garden clean up. Ideally, you should wait until the daytime temperatures are consistently above 50 degrees F for at least 7 consecutive days.
Morning glories vary in their hardiness. Many are not frost-tolerant. … The moonflower (Ipomoea alba) grows as a perennial in U.S. Department of Agriculture plant hardiness zones 9 through 11, and the common morning glory (Ipomoea tricolor) is hardy in USDA zones 10 and 11.
virescens (prairie larkspur) occurs in Minnesota.
The flowers of zinnia (Zinnia spp.) and dahlia (Dahlia spp.) are alike in many ways. They’re both members of the sunflower family, or Asteraceae, with similar flower construction.
The most recent cold hardiness zone map was released in 2012 and most of Minnesota is in USDA Zone 4, which means the extreme low temperature in the zone gets to between -20 F and -30 F.
In Minnesota, dahlias are treated like annuals. Dedicated dahlia growers will dig up the tubers and store in a cool dry place over the winter.
Daffodils are one of the easiest perennial plants to grow in Minnesota! Many, many varieties are reliably hardy here. They’re not just yellow anymore—pinks, oranges, whites, reds and greens have been created. Deer, squirrels and rabbits leave them alone, unlike other spring bulbs.
October, it is not really too late to plant most trees, perennials and shrubs until the ground is frozen. … In the spring, continue to water the plant regularly for several weeks, until it gets established well. To tell whether a plant needs watering, stick your finger an inch down into the soil around the plant.
In a flower border, remove weeds and amend the soil. If this is a new bed, put down a layer of landscape fabric to block weeds and top with six inches or more of garden soil or top soil. In an existing bed, amend the soil with composted manure before planting. The ideal location will need adequate drainage.
- Work the soil when it is moist, but not wet.
- Turn the soil over to a depth of at least 12 inches.
- Add 2-3 inches of compost and turn it into the bed.
- Either cover the bed with a thick (3-4″) layer of mulch or use a weed and feed to help keep weed seeds from germinating.
Start tomatoes from seeds indoors, five to six weeks before planting outside. In most of Minnesota, this is mid-April.
Start seeds indoors in early April for transplanting in late April and early May. Fertilize soil for quick growth and keep the soil moist. Direct seed as soon as the soil is workable in April. Start seeds indoors in July for transplanting in August for a late season crop.

When wintering over gardenia plants indoors, keep in mind that these are evergreen shrubs that don’t go dormant in winter, so you will need to continue to provide optimal growing conditions. … The shrub will survive warmer night temperatures but it may not flower well when you take it back outdoors.
Gardenia (Gardenia jasminoides), a woody perennial shrub, grows in U.S. Department of Agriculture plant hardiness zones 8 through 11. If you’re growing gardenias in a cooler climate, plant them in containers and bring them indoors for the winter.
Tree hydrangeas (Hydrangea paniculata), also known as panicle hydrangeas, are a fast-growing flowering shrub with an upright growth habit. … The shrub has oval, toothed, dark green leaves, and it produces cone-shaped flower panicles that stretch around 7 inches long with clusters of small, creamy white blooms.
Zinnias are annuals, meaning that they go from seed to flower to seed quickly.
It is illegal to grow Papaver somniferum in the United States because the unripe seed pods contain the milky substance that is scraped out and dried to become opium, so possession of the plant can be looked upon as possession of the drug.
Start perennial poppies outdoors in early spring, when some chance of frost is still a possibility. Start annual varieties outdoors at the same time in Zones 3-7. In Zones 8-10, the best bet is to direct sow in the fall. Poppies are famously difficult to transplant, so starting them indoors is not recommended.

The Best Time to Plant Your Garden For most of the United States, the best time to start spring crops is, well, now. But to get more exact planting recommendations based on your area, use this handy calendar. (As a general rule, you should plant hardy greens and cole crops a few weeks before your final frost.)
WHEN TO PLANT PANSIES Pansies can be planted in the early spring or the fall. Pansies can be finicky to start from seed; it’s a lot easier to buy established plants from a local nursery. Plus, you’ll get blooms a lot sooner.
The short, quick answer is, yes. Because they have little freeze tolerance, most will die in sustained winters. In areas with moderate temperatures, they may come again in spring, especially if they were mulched to protect the roots.
Pansies are short-lived perennials. Have you ever planted a six-pack or two for some spring color and noticed later in the season that they’ve disappeared? I already mentioned that they love cool weather, but they don’t do well in the heat.
