Unlocking Summer’s Palette: 9 Flower Seeds to Plant in May
Shakespeare may have been fond of the darling buds of May, but they don’t appear by magic. Behind every burst of early summer color is a well-timed sowing – and, as it happens, May is one of the best moments in the gardening calendar to get started. Forget complicated setups and lengthy waits; May offers a golden window for sowing a surprising number of dependable blooms. These aren’t the fussy, high-maintenance varieties demanding constant attention. Instead, we’re focusing on flowers that thrive on relatively little fuss, offering a rewarding, continuous display that stretches from summer into fall. This isn’t about chasing trends; it’s about cultivating a vibrant, resilient garden that rewards your efforts with a riot of color and attracts buzzing pollinators. Let’s delve into nine exceptional flower seeds to plant in May, each with its own unique charm and benefits – and, crucially, how to maximize your chances of success.
1. Zinnias: The Cut-and-Come-Again Champions
Zinnias (Zinnia elegans) are, without a doubt, the workhorses of the summer garden. Their bold, cheerful blooms and remarkably quick germination make them a fantastic choice for novice gardeners and experienced growers alike. Direct sowing them in batches every 2-3 weeks after your last frost guarantees a continuous supply of vibrant pinks, oranges, reds, yellows, and even purples. They germinate in days, providing an immediate burst of color that’s hard to resist. What’s truly remarkable about zinnias is their ‘cut-and-come-again’ nature; the more you snip off the blooms, the more the plant produces. They thrive in heat, tolerate drought, and are remarkably adaptable to various soil conditions. Interestingly, studies have shown that zinnias can actually improve the flavor of nearby vegetables – a bonus for those growing their own food! The key to success with zinnias lies in consistent deadheading (removing spent blooms) to encourage continued flowering. Many seed packets indicate that they germinate in as little as 7-10 days – that’s practically instantaneous! For a diverse mix of colors and forms, consider Burpee’s Cut and Come Again Mixed Colors Zinnia Flower Seed. The impressive germination rate and wide variety make them a reliable choice for any May sowing.
2. Cosmos: Effortless Height and Movement
If you’re seeking a flower that embodies relaxed beauty and low-maintenance gardening, cosmos (Cosmos bipinnatus) are an excellent selection. Their airy foliage and daisy-like flowers create a sense of movement and lightness, adding a touch of the meadow to borders and containers. Cosmos aren’t demanding; in fact, they thrive when slightly neglected. They’re remarkably tolerant of poor soil and even benefit from a bit of dryness. This makes them particularly well-suited for gardeners who aren’t keen on constant watering or fertilizing. A fascinating detail is that the more you prune them, the more flowers they produce – it’s a virtuous cycle of bloom. They are also a fantastic choice for attracting pollinators, especially butterflies. They’re generally available in shades of pink, white, lavender, and yellow, offering a range of color options. To ensure a healthy and prolific bloom, consider sowing Burpee Gazebo Mixed Colors Cosmos Flower Seed in May. Don’t overwater them, and they’ll reward you with weeks of stunning color.
3. California Poppies: Self-Seeding Success
For a touch of rustic charm and a surprisingly easy gardening experience, California poppies (Eschscholzia californica) are a top contender. These iconic flowers, with their silky petals and vibrant orange, yellow, and cream hues, are known for their self-seeding ability. Once sown, they often spread and reseed themselves, providing repeat color year after year in warmer zones. This self-seeding characteristic makes them incredibly forgiving and reduces the need for replanting each season. They are exceptionally drought-tolerant, making them perfect for dry or low-water gardens. And, as an added bonus, they’re incredibly easy to sow directly into cracks or gravel if you’re short on space or prefer a more informal planting style. The Burpee Sunset Mixed California Poppy Flower Seed is a popular choice, offering a beautiful range of shades. The fact that they often self-seed means you can plant them once and enjoy them for years to come – a testament to their resilience and adaptability.
4. Sunflowers: A Towering Delight
Nothing says summer quite like sunflowers (Helianthus annuus). From towering giants that reach for the sky to compact varieties perfect for containers, sunflowers offer a diverse range of sizes and shapes. They’re quick to grow, loved by pollinators, and provide a spectacular visual display. The sheer scale of a mature sunflower is awe-inspiring, and their bright yellow petals brighten any garden. There’s really a sunny sunflower to suit everyone. We’re fond of the hues in this Burpee Fun N Sun Blend Sunflower Seeds if you can’t choose your favourite! Smaller varieties like Burpee Tiger Eye Sunflower Seeds are ideal for containers on a porch or patio, while Burpee Kong Sunflower Seeds offer a truly impressive, oversized display. Sunflowers are relatively easy to grow, but they do require plenty of sunlight and well-drained soil. Consistent watering is important, especially during dry periods.
5. Nasturtiums: Ornamental and Edible
Let’s be honest: nasturtiums (Tropaeolum majus) are a no-brainer when you’re picking out flower seeds in May. These cheerful flowers are incredibly easy to grow, pest-resistant, and bloom non-stop until the first frost. They offer vibrant blooms in fiery shades alongside trailing or bushy foliage, adding a pop of color to salads, sandwiches, and other dishes. Nasturtium flowers and leaves are all edible and have a peppery, slightly spicy flavor. They’re incredibly versatile in the garden, serving as excellent companion plants in vegetable gardens, too, as they deter aphids and other pests. Plus, their prolific blooming habit means you’ll have a constant supply of colorful flowers and flavorful leaves. Consider Burpee’s Nasturtium Flower Seed Mix for a variety of colours and forms – they’re incredibly easy to grow, pest-resistant, and bloom non-stop until the first frost.
6. Cornflowers: A Cottage Garden Classic
Cornflowers (Centaurea cyanus) evoke a quintessential cottage garden aesthetic. Their delicate, nodding blooms in shades of blue, purple, pink, and white bring a touch of old-fashioned charm to borders and wildflower meadows. They’re relatively easy to grow from seed and self-seed readily, ensuring a continuous supply of blooms. Cornflowers thrive in well-drained soil and benefit from full sun. They’re a favorite of bees and butterflies, adding to the biodiversity of your garden. They’re a fantastic choice for adding a touch of nostalgia and beauty to your garden. Look for Burpee’s Mixed Cornflower Seeds for a selection of beautiful colours. Their delicate beauty and effortless growth make them a welcome addition to any May sowing.

Sweet peas (Lathyrus odoratus) are renowned for their intoxicating fragrance and elegant, climbing vines. Planting them in May allows you to enjoy their beautiful blooms throughout the summer months. They require support, such as a trellis or netting, to climb on. Sweet peas thrive in well-drained soil and benefit from regular watering. They prefer a sunny location but can tolerate partial shade. The fragrance of sweet peas is truly remarkable, filling the air with a sweet, honey-like scent. They’re a beautiful addition to hanging baskets, fences, or arches.

Its bright orange and yellow flowers are not only visually appealing but also packed with beneficial compounds. Calendula is easy to grow from seed and thrives in sunny locations with well-drained soil. It’s a fantastic companion plant for vegetables, helping to deter pests and improve soil health.

Larkspur (Delphinium elatum) are tall, stately flowers that add drama and elegance to any garden. They produce striking spikes of blue, purple, pink, and white blooms. Larkspur require support to grow upright and benefit from well-drained soil and full sun. They’re relatively easy to grow from seed, but they do take a bit longer to mature than some of the other flowers on this list – typically around 60-90 days. However, the reward is a stunning display of tall, colorful spires that will impress even the most discerning gardener. Consider Burpee’s Larkspur Seed Mix for a variety of colours and heights. They’re a great choice for adding height and drama to borders and cottage gardens.
