What is the most hardy annual flower?
Alyssum, bachelor’s buttons, calendula, cleome, delphinium, foxgloves, larkspur, lisianthus, pansies, and rudbeckia—these gorgeous flowers are all easy-to-grow, hardy annuals that thrive in the colder temperatures in spring and fall. Plant with annual pansies in spring and fall, and layer in daffodils and crocus to emerge in early spring. In summer, fill in with annuals like impatiens and vinca. If you have room, a small daylily variety like Stella d’oro will bring color on hot summer days.
Which plant will last the longest, annuals or perennials?
Annuals complete that cycle in one growing season, whereas perennials live on for three years or longer. But, if you begin studying the labels on your new plant or seed packet purchases, you’ll discover many twists on this basic definition. Marigolds need full sun to encourage plenty of flowers and do best in a reasonably fertile, but well-drained soil. In borders, improve poor soil with well-rotted compost or soil conditioner in advance of planting. Use peat-free, multi-purpose potting compost for pots.Marigolds need full sun all day to provide blooms all season long. Three common types are French, African, and Signet. Marigolds naturally repel pests such as deer or rabbits since they find their odor offensive.Marigolds are sun worshippers, thriving with at least six hours of direct sunlight daily. When they’re basking appropriately, you’ll notice vibrant blooms and sturdy stems, a clear sign of a sun-kissed plant living its best life.Actually, both! Most marigolds are annuals, but a few are perennials. Marigolds self-seed so they may appear to be a perennial when in reality, they are just coming back from seed.While most Marigolds are grown as annuals, there are some perennial species that will survive in warmer climates. With over 50 species of marigold available, three dominate the bedding flower market: The tallest are African marigolds (T.
How long do zinnias bloom?
These are true cut-and-come-again flowers, meaning the more you harvest, the more they produce. Unlike some flowers that bloom in one big flush and then fade, zinnias will churn out fresh blooms for weeks at a time—usually right up until the first frost. Light: Zinnias grow and flower best in full sun. They can flower in part shade, especially in warmer climates with afternoon shade, but they may be more susceptible to disease and have fewer flowers. Soil: Zinnias grow best on fertile, well-drained soils high in organic matter.Zinnias require regular watering, but do not overwater as they can tolerate drier soil better than overly wet soil, and too much water can cause fungal diseases. Only water when the top 1-2 inches of soil are dry, and try to water the base of the plant and not the foliage when possible.Hardiness: Zinnias are typically grown as annuals, meaning they complete their life cycle in one growing season and do not survive frost. In terms of USDA hardiness zones, zinnias are typically grown in zones 2-11 as annuals. Height: Some zinnias are low-growing and compact, while others can grow quite tall.Yes, cutting zinnia stems to display in a vase causes the plant to produce more blooms. So don’t be afraid to cut zinnias in your cutting garden—it encourages more flowers.Zinnias thrive in full sunlight and should be planted at the beginning of the warm weather season. They are short-day plants that flower when the day length is less than 11 hours; therefore, they are perfect for early spring planting when the nights are longer, Mbofung-Curtis says.
Is Zinnia flower annual or perennial?
If there’s an easier flower to grow, we’d like to know about it. Zinnias are annuals, meaning that they go from seed to flower to seed quickly. Many flower varieties thrive in full-sun gardens. Some of the more commonly planted full-sun flowers include marigolds, milkweed, dahlias, sage, lavender, catmint, shasta daisies, hibiscus, bee balms, and various ornamental grasses.The easiest flowers to grow from seed include zinnias, marigolds, sunflowers, cosmos, and calendula; all annual flowers.

How long do marigolds bloom?
Most varieties bloom from early summer until hard frost in late fall. Marigolds require full sun and grow best in well-drained, loamy soil. The largest group of marigolds are named Tagetes and are half-hardy annuals, meaning they are tender and won’t tolerate frost. They flower for months through summer and into autumn and vary from plain single colours to a range of contrasting markings of red, brown, yellow, or orange.Smaller marigolds make good edging plants for borders and do well in pots, while taller or larger-flowered marigolds can be grown in large pots or in borders. Marigolds thrive in a sheltered site, and shelter is particularly important for African marigolds as the big blooms can be easily damaged by wind.Watering: Marigolds prefer the soil to dry out in between watering; yet can also be finicky if their leaves are wet. Plan to water at the base of the plant, and keep soil moist, yet not overly wet.
