Do snapdragon seeds come back true?
Snapdragons are short-lived, tender perennials, but are usually grown as annuals in the UK. If you want them to come back year after year, it’s best to take cuttings or collect seed, although seed may not come true to type. Snapdragons are great plants for containers, baskets, or filling garden wall crevices as they can fit a variety of areas. From germination to flowering takes about two or three months, and as a result are often started indoors weeks—or even months—before the last frost.Snapdragons love nighttime temperatures in the low 40s and daytime temperatures in the low 70s. This makes them ideally suited for Georgia’s fall season. The ideal time for planting snapdragons is when temperatures are 60 to 75 degrees during the day and 50 to 55 degrees at night.Since most snapdragons perform best in the cooler months, the best time to plant them is in early spring (colder climates) or fall (warmer climates). Because they will tolerate light frosts, they can be set out in the spring garden a week or two before the average last frost date in your area.Snapdragon seeds benefit from a cold period, so after the time in the refrigerator, start Snapdragon seeds indoors 8 – 10 weeks prior to the end of frost season. Transplant outdoors in mid-spring. They do tolerate a light frost and cold nights will produce sturdier stems.In some areas of the country, snapdragons are treated as short-lived tender perennials. Most snapdragons are hardy in USDA Zones 7 to 11, or, more likely, 8 to 11. While they may grow back in the spring in warmer regions, they might not bloom with the same vigor as they did in their first year.
Can you sow snapdragon seeds in the fall?
To ensure I have lots of early flowers each spring, I fall sow a lot of flower seeds. Snapdragons are especially cold hardy, and despite being slow to start and grow, are vigorous once started. In zones 7 and higher, Snapdragons can be direct sown or started indoors in the fall, and survive outside over winter. They look similar to poppy seeds. Because they are so small, it’s not worth sorting through snapdragon seeds to find the best-looking ones. When the time comes next year to start the seeds, use them all. Some will germinate and sprout and others won’t, but you should get enough seedlings.Snapdragons can be a little tricky to start from seed. For best results, I like to keep the seeds in the freezer until I’m ready to sow them. This mimics their natural life cycle of germinating after a season of cold temperatures. Snapdragon seeds are absolutely tiny.Starting your snapdragon seedlings indoors is a smart way to give them a headstart. It sets the stage for a healthy growing season and creates a controlled environment where your seedlings can thrive.Yes, Snapdragons grow equally well in containers and pots as in beds. Make sure your pots are big enough to support the size of the Snapdragon you choose, and use a good peat-free compost.
Are Snapdragon seeds hard to germinate?
While it is possible to direct sow Snapdragon seeds outdoors after the last hard frost, germination rates are much harder to predict, and starting indoors is the preferred, recommended method. A good rule of thumb is to sow annual flower seeds as early after the last spring frost as possible. For early-spring perennial blooms, plant these types of flower seeds in late summer to early fall so that they can germinate over winter.Many native seeds need to have a winter period of cold moist temperatures to break dormancy and germinate. Not all native seeds require this cold period for germination, but every seed can be sown outdoors in the fall or winter.Indoors: Sow seeds indoors from late winter to early spring (January to March) to give plants a head start. Outdoors: Direct sowing is possible from March to April, once the danger of frost has passed.As the name suggests, winter sowing is done during the cold winter months. You can start seeding anytime from December through February, depending on your location and climate. If you sow seeds too early in autumn the seeds may sprout and not survive winter.
Do snapdragon seeds need cold stratification?
Snapdragons prefer moist cold stratification. The refrigerator is cold enough to accomplish this task. You’ll also need a watertight container or sealable bag and a couple of paper towels or substrate. Moisten the paper towels or the growing medium, and sprinkle your seeds on top. Don’t cover as Snapdragon seeds require sunlight to germinate. Keep moist, and place trays in a warm, sunny location. Grow lights can be used, as well, giving the seeds about 16 hours of light exposure each day. You should see germination in 10 to 14 days.No, generally snapdragons do not grow back every year. Most snapdragons are annuals; however, if you live in zones 7 through 11, they may return for a few years. If you live in a wintery-weather zone, they can self-seed and may return to your garden from seed left behind.On to Snapdragon and Pincushion Seeds, & More Snapdragons in particular were challenging for me to get good germination. I sowed the snapdragon seeds in damp towels on March 24 and by March 30 they were ready for planting into soil blocks!Snapdragons thrive in cool temperatures. For the best results, start seeds in late fall and grow them slowly in a minimally heated greenhouse or under low tunnels.
What is the lifespan of snapdragons?
Are Snapdragons Low-maintenance? These fast-growing, short-lived perennials (averaging a three-year life span) are very low maintenance. With only the right amount of sunshine and moisture, they will thrive. They will benefit and blooms are more abundant with some deadheading, also. Planting them too close to drought-tolerant shrubs will make it difficult to keep all the plants happy. Snapdragons planted near evergreen conifers or large established trees will likely not flower well due to a lack of moisture.In zones 7 and higher, Snapdragons can be direct sown or started indoors in the fall, and survive outside over winter.Although they are known for blooming in the spring, if kept watered in the summer and deadheaded, they could bloom again. I winter sow snapdragons for several reasons: 1) starting from seed provides a wider range of varieties; 2) starting from seed is cheaper; and 3) winter sowing gives me a jump on the spring season.
