Perennials Requiring Stratification
For many perennial flowers, beginning from seed presents an unnecessary hurdle due to a process called cold stratification. This involves artificially
mimicking winter conditions, typically by refrigerating the seeds for a set period before planting, to trigger germination. Experts like Dillon suggest this adds significant complexity, making it a less desirable starting point for gardeners aiming for simplicity. Plants such as echinacea, milkweed, and delphinium, which often fall into this category, are frequently more successfully and easily obtained as established plants from nurseries, bypassing this intricate preliminary step.
Slow-Germinating Succulents
Enthusiasts dreaming of lush succulent arrangements might be disheartened to learn that growing these popular houseplants from seed is an exercise in extreme patience. Succulent seeds can take an astonishingly long time to sprout, often up to a full year. This lengthy germination period makes it impractical for most gardeners. Instead, propagation from existing succulent plants, even from fallen leaves, is a far more efficient and rewarding method, quickly yielding new plants without the long wait and uncertain outcome of starting from tiny seeds.
Challenging Garlic Cultivation
While it is technically possible to grow garlic from seed, it's a path that most experienced gardeners strongly advise against. Garlic doesn't typically thrive when cultivated this way; the vastly preferred and more successful method is to plant cloves directly into the soil. Even leftover garlic from your kitchen, perhaps nearing the end of its freshness, can be repurposed for planting. Each individual clove within a garlic bulb has the potential to grow into a new plant, offering a much quicker and more reliable route to harvesting your own garlic than the arduous journey from seed.
Impractical Lavender Seeds
The process of germinating lavender seeds is notoriously lengthy, making it a less-than-ideal choice for most home gardeners. Given how easily and affordably lavender plants are available at garden centers, starting from seed is often considered a waste of time and effort. Furthermore, purchasing a young lavender plant allows you to benefit from the expertise of nursery staff, who can guide you to the variety best suited for your specific climate and growing conditions, ensuring a higher chance of success than with unpredictable seed-starting.
Thorny Rose Beginnings
Cultivating roses from seed is an option, but it's a venture that most seasoned gardeners actively avoid. The journey from a rose seed to a blooming plant can be exceptionally long and fraught with challenges. Rose bushes are far more commonly and successfully propagated through stem cuttings taken from established, non-grafted plants. This method is significantly easier and more efficient for replicating favorite rose varieties, allowing gardeners to enjoy beautiful blooms in a reasonable timeframe rather than waiting potentially years for a seed-grown rose to mature.
Tedious Snapdragon Sowing
Snapdragons, while capable of growing from seed, present a frustrating sowing experience due to their minuscule seed size. The tiny nature of snapdragon seeds makes them incredibly easy to miss during the sowing process, leading to sparse or uneven germination. Considering how readily available snapdragon plants are at nurseries and garden centers, especially as warmer weather arrives, it's far more practical to purchase them. This saves gardeners the hassle and potential disappointment of a tedious and often less successful seed-starting effort.
Unconventional Potato Planting
Although botanically possible, growing potatoes from seed is an almost unheard-of practice among gardeners. Potatoes primarily develop from tubers, which are essentially underground storage organs. If you find potatoes in your home beginning to sprout eyes, these can be directly planted to grow new potato plants. The process involves slicing the potato into sections, ensuring each piece has at least one eye, allowing it to dry slightly, and then planting it eye-side up about six to eight inches deep in the soil. This tuber-based propagation is the standard and most efficient method.
Rare Sweet Potato Seeds
The idea of growing sweet potatoes from seed is largely theoretical for most gardeners and farmers, as it's an uncommon and unreliable method. While sweet potatoes can technically produce seeds, this occurrence is infrequent, making it an impractical approach for cultivation. Historically, sweet potatoes have been propagated through cuttings, creating a continuous lineage. The prevalent and efficient method for growing sweet potatoes involves using 'slips,' which are the young shoots that emerge from a mature sweet potato, ensuring a reliable start for the crop.
Slow Rosemary Germination
Rosemary, a beloved herb, is another plant that experts recommend starting from a nursery-bought plant rather than from seed. Rosemary seeds are known to take an exceptionally long time to germinate, and even after sprouting, the seedlings grow at a very slow pace. This extended period of waiting and slow development can be discouraging. Purchasing a young rosemary plant allows gardeners to bypass these initial challenges and focus on nurturing a robust plant more quickly, leading to a more satisfying gardening experience.
Convenient Onion Bulbs
While onions can indeed be grown from seed, the vast majority of gardeners opt for a far more direct and efficient method: planting onion bulbs. The seed-starting process for onions is considerably more time-consuming and laborious. Planting bulbs directly into the soil, just an inch deep with the bulbous end down, yields harvestable onions within three to four months. This significantly shorter timeframe, compared to the extended duration required for seed germination and growth, makes bulb planting the overwhelmingly preferred choice for practical onion cultivation.
Biennial Foxglove Plugs
Foxgloves are biennials, meaning they typically flower only in their second year. Instead of engaging with their tiny seeds, which are easily outcompeted by weeds and difficult to manage, experts recommend purchasing foxglove plugs. These pre-started plants offer a much more robust beginning, often blooming in their first year. Starting with a slightly larger, more established plant gives it a better chance to thrive and establish itself in the garden, circumventing the delicate and often frustrating process of seed germination.
Impatient Lisianthus Growth
Growing lisianthus from seed demands a significant investment of time and patience, often taking twelve to sixteen weeks just to reach a transplantable size. During this extended period, numerous factors can go awry, leading to potential failure. For this reason, gardeners are strongly advised to purchase lisianthus plugs from nurseries or garden centers. This approach bypasses the lengthy and precarious germination and early growth stages, offering a much more reliable and less stressful way to enjoy these beautiful flowers in your garden.
