When to Plant Bulbs for Summer: A Complete Planting Calendar for 2026

The Complete Flower Bulb Garden from Willard & May is a straightforward way to get a long season of color in your garden. This 78-bulb collection includes gladiolus, calla lilies, and other perennials chosen for their ability to bloom from July through early October. It's aimed at anyone who wants a showy display without a lot of fuss, from beginners to experienced gardeners.

The standout feature here is the extended bloom time. With a mix of varieties that flower at different points in the summer, you get roughly 50 days of continuous color. The bulbs are easy to plant in full sun or partial shade, and they do well in both garden beds and containers. The tall gladiolus and lilies add nice vertical height, reaching up to four feet, which works well in borders or as a backdrop.

In terms of design, the mix offers a range of bloom shapes and colors that attract pollinators. You get 18 Tutti-Frutti Gladiolus, 40 Harlequin Flowers, 10 Stargazer Lilies, and several other types, creating a varied look. The bulbs are described as organic and require moderate watering, making them fairly low maintenance. They're also hardy in zones 3-9, so they can naturalize and come back year after year.

One potential drawback is that the mix's success depends on your site conditions. If you have heavy shade or poor drainage, some bulbs may not perform as well. Also, the package doesn't include detailed care instructions, so you may need to look up specific needs for each variety. But for the price, it's a solid value for a summer-long display.

Overall, this is a good choice for anyone wanting a reliable, colorful garden from mid-summer into fall. The mix is diverse enough to keep things interesting, and the low-maintenance approach makes it easy to get started. Just plant them in well-drained soil with some sun and you'll get a nice show for months.

If you have a shady spot in your yard that could use some summer color, the Willard & May Complete Shade Perennial Flower Bulb Garden is a practical and attractive solution. This set includes 30 bulbs: 15 Mixed Hosta and 15 Mixed Astilbe, chosen specifically for low-light conditions. The goal is to provide 50 days of continuous blooms from July through October, making it a solid pick for gardeners who want reliable color without constant fuss.

The standout feature here is the combination of contrasting plants. Hostas bring bold, textured foliage that fills space and stays interesting all season, while Astilbe adds upright plumes of flowers that introduce vertical variety and bright color. Together they create visual depth and keep shaded areas engaging from spring through summer. The bulbs are also pest resistant, which means less worry about deer or rabbits munching on them.

Design and build quality are what you would expect from a family-owned company with over two decades in the business. The bulbs come from a warehouse in Milwaukee, Wisconsin, and the brand emphasizes organic material and reliable growth. They recommend planting in well-drained soil with consistent moisture, and once established these perennials return year after year. That makes them a smart long-term investment for any shade garden.

One potential drawback is that there are no customer reviews yet, so you are buying based on the brand's reputation rather than user feedback. Also, the bulbs require proper planting depth and spacing, which might take a little extra effort if you are new to gardening. But the instructions are straightforward, and the payoff is a lush, low-maintenance shade garden that keeps blooming into fall.

Overall, the Willard & May Complete Shade Perennial Flower Bulb Garden is a well-thought-out kit for anyone looking to add color and texture to shady spots. It is easy to plant, pest resistant, and designed to deliver season after season. For the price, it offers good value, especially for beginners or those who want a curated mix that works.

The WillardMay Asiatic Lilies Mix comes as a pack of 10 freshly dug bulbs, designed for gardeners who want a reliable splash of summer color. These perennials are a solid choice for both new and experienced growers, offering tall, upright stems and bold, bright flowers that work equally well in garden beds or as cut arrangements. The bulbs are large, measuring 12-14 cm, which gives them a head start on vigorous growth.

In real-world use, most buyers report excellent germination with all 10 bulbs sprouting and growing into healthy plants. The flowers can reach impressive heights, often close to the gardener's own height, and the vivid colors — electric orange, yellow, and red — create a lively display. A few customers noted that the color mix was not as varied as expected, with some packs containing only yellow and orange blooms. If a specific multicolor arrangement is important to you, this may be a point to consider.

Build quality and bulb health are generally good, though the bulbs can begin sprouting during transit, leading to delicate sprouts that may break off when handled. WillardMay's customer service is known for stepping in with replacements in these cases, which adds some peace of mind. The 100% grow guarantee also helps offset the occasional loss. For care, these lilies need well-drained sandy soil and full sun, with moderate watering and a little staking for support as they grow tall.

The main drawbacks come down to color consistency and the fragility of pre-sprouted bulbs. Some stems may also require staking to keep them upright. But for the price, you get healthy, vigorous plants that bloom reliably and multiply over the years. Just be prepared to stake them and understand that the color assortment may not be exactly what you saw in the listing photo.

Overall, the WillardMay Asiatic Lilies Mix is a strong performer for anyone wanting easy, tall perennial flowers. The high germination rate, good customer service, and vibrant results make it a worthwhile buy. If you can work around the occasional color surprise and the need for staking, you will enjoy a garden full of cheerful summer blooms.

The CZGrain Complete Spring Flower Garden is a 50-bulb collection that promises a season of color with tulips, daffodils, crocus, and gladiolus. It's designed for anyone who wants a low-maintenance garden, from first-time planters to seasoned gardeners looking for a convenient mix. The bulbs come individually bagged, which helps keep them fresh and organized until you're ready to plant.

In terms of performance, most buyers report healthy bulbs that sprout reliably when planted according to the simple instructions. The mix offers a nice spread of bloom times, with crocus popping up early, followed by daffodils and tulips, and gladiolus adding height later in summer. A few reviews mention that some bulbs arrived in less-than-perfect condition, but the majority found them to be good quality for the price. The brand's commitment to heirloom varieties and careful packaging from their Iowa farm adds a layer of trust.

Design-wise, the bulbs are standard size and ready to go. The packaging is functional, with each type separated so you can plan your layout. The product is versatile enough for flower beds, borders, or containers, and it can even be grown indoors if you have a sunny spot. The heirloom material feature means these are open-pollinated varieties that can be saved and replanted, though most people will treat them as annuals or perennials.

One honest drawback is that not every bulb may sprout, as noted in a few reviews. This is common with bulk bulb mixes, but it's worth considering if you need guaranteed results. Also, the mix can vary by season, so you might not get exactly the same types every time. However, the overall value and ease of use make it a solid choice for casual gardeners.

Overall, the CZGrain Spring Flower Garden is a practical, affordable way to add color to your space without much effort. It's especially good as a gift for someone who loves flowers but doesn't want to fuss over complicated planting. If you're okay with a little unpredictability in the mix, this is a worthwhile purchase.

If you're looking to add a pop of color to a shady corner of your yard or brighten up a dim indoor space, the Country Creek Acres Caladium Bulbs Fancy Mix is a solid choice. This 10-pack brings together several of the brand's most popular fancy-leaf caladium varieties, creating a stunning mosaic of colorful heart-shaped foliage. They're designed for anyone from beginner gardeners to seasoned green thumbs who want a low-fuss, high-impact planting option.

The standout feature here is the mix itself. Each pack contains a random assortment of fancy caladiums, meaning you get a beautiful combination of greens, pinks, reds, and whites with different vein patterns. They thrive in full shade and only need moderate watering, so you won't be tied to constant maintenance. Plus, deer tend to leave them alone, which is a huge bonus if you battle wildlife nibbling your plants. These bulbs are also GMO free, and the large size helps ensure strong growth year after year if you lift them before the cold sets in.

In terms of build quality, the bulbs arrive firm and ready to plant. They're light (2 ounces total for the pack) and come packed in simple packaging. While the lack of customer reviews means we can't gauge long-term performance from other buyers, the brand Country Creek Acres has been around for years, and the product's specifications are straightforward. Just be aware that these caladiums love shade, not direct sun, and they need warm soil (nighttime temps in the high 60s) before going outside. They're also not winter hardy in zones below 9, so expect to dig them up in the fall if you live in colder regions.

On the downside, the pack is a little expensive per bulb compared to buying individual varieties, but the convenience of a pre-selected mix is worth it for many gardeners. Also, since caladiums are tender perennials, they won't survive a frost. If you're in zone 3-8, treat them as annuals or store the bulbs indoors. But overall, this is a great way to fill a shady spot with nonstop color from summer through early fall, and it works just as well in pots on a covered porch as it does in a garden bed.

Verdict: For anyone wanting an easy, deer-resistant, shade-loving plant that offers a stunning foliage display, Country Creek Acres Caladium Fancy Mix is a reliable pick. Just manage your expectations about winter care, and you'll enjoy vibrant leaves all season long.

The GardeningProducts4Less Complete Spring & Summer 100 Bulb Collection is a thoughtfully curated set designed to deliver a continuous parade of color from early spring through late summer. It includes 30 Anemone Blanda (soft whites and lavenders), 20 Gladiolus Mixed (rainbow of vibrant colors), 20 Allium Moly (golden-yellow star-shaped clusters), and 30 Ixia Mixed (pinks, purples, whites). This collection is ideal for both novice and experienced gardeners who want a low-effort, high-impact perennial garden that also supports pollinators like bees, butterflies, and hummingbirds.

In real-world use, the staggered bloom times work well. Anemones emerge first in spring, followed by Allium Moly in late spring, then Gladiolus and Ixia through summer. The bulbs are easy to plant just place them in well-drained soil in full sun, water moderately, and they grow. They are hardy in USDA zones 3-10, making them suitable for a wide range of climates. The flowers attract beneficial insects, adding life and movement to the garden.

Build quality is solid for bulk bulbs. They are shipped dormant and packed to survive transit. The mix of colors and forms creates a natural, cottage-garden feel. However, because the colors are mixed, you won't have control over exact shades. Gladiolus can grow tall and might need staking in exposed spots. Also, some bulbs might be smaller than expected, but they still produce flowers.

One honest drawback is that the bulbs are best planted in fall, so if you miss that window, you might need to store them properly. Also, while the collection is perennial, some varieties like Gladiolus may need winter protection in colder zones. The lack of reviews makes it hard to gauge long-term performance, but the brand has sold thousands, suggesting customer satisfaction.

Overall, this 100-bulb pack offers excellent value for creating a pollinator-friendly, low-maintenance flower garden. It's a practical choice for anyone wanting to add reliable, recurring color without a lot of fuss. If you're looking for a diverse, easy-to-grow perennial mix, this collection is worth considering.

If you are looking for a budget-friendly way to fill shady spots in your garden with colorful foliage, the 185+ Mixed Color Hosta Seeds offer an appealing option. This generic pack promises a mix of blue, purple, and white hues with varied leaf patterns, all from seeds rather than bulbs. The idea is to get a perennial ground cover that returns every year with very little effort on your part.

The standout features are definitely the shade tolerance and low maintenance. Hostas are classic plants for areas that get little direct sunlight, and these seeds are marketed for USDA zones 3 through 9. They are also supposed to attract hummingbirds and butterflies while resisting deer and rabbits. That combination of beauty and practicality is hard to beat in a seed packet.

Real-world performance is a mixed bag based on user experiences. Some gardeners report fast germination using a wet paper towel method, with sprouts appearing within a week. Others, however, had no luck at all. Several reviews mention seeds that were already cracked or turned moldy, and a number of customers found the seeds simply would not germinate even with careful attention. The inconsistent results are the biggest issue with this product.

On the plus side, the seeds are non-GMO and heirloom, and the price is very competitive for the quantity. But be prepared: there are no instructions included, which is a drawback for beginners. The tiny seeds require a gentle touch and a bit of know how to get them started. If you do succeed, the plants are tough, drought tolerant, and come back stronger each year.

Overall, these hosta seeds are a gamble. They could work out beautifully if the batch you receive is fresh and viable, especially if you have experience starting seeds. But if you want a sure thing, you might be better off buying established plants or a different brand with better germination guarantees. For patient gardeners who enjoy the process and want to save money, these are worth a try.

The Willard & May Mixed Gladiolus Flower Bulbs offer a budget-friendly way to fill your garden with tall, colorful blooms. With 50 bulbs in assorted colors, this pack is designed for gardeners who want a big visual impact without breaking the bank. The brand has been in the horticulture game for over 20 years, and they focus on making outdoor spaces more enjoyable with easy-to-grow bulbs.

Key features include long flower spikes that are ideal for cut flower arrangements. Gladiolus symbolize strength and remembrance, which adds a thoughtful touch to any planting. They also attract bees and butterflies, helping your garden support local pollinators. These perennials are simple to plant: just place them 3 to 4 inches deep, space 6 to 9 inches apart, and they'll thrive in sandy or well-drained soil with moderate watering. With a height of 36 to 48 inches, they make a dramatic statement in beds, borders, or large containers.

Real-world performance varies. Many buyers report strong germination rates, with one customer seeing 42 of 50 bulbs sprout in just ten days. Others note that the bulbs arrive looking dry, which is typical, but a few found them too small or moldy. The biggest complaint is color inconsistency: some reviewers received only white flowers instead of the advertised mix. However, others were delighted by the variety and vibrant blooms that returned each season.

Build quality is acceptable for the price point. The bulbs are generally healthy, though size can be smaller than premium competitors. The package includes 12-plus cm bulbs, which is standard for bulk gladiolus. For gardeners who need a large quantity for a low cost, this is a solid option. Just keep in mind that you might need to order extra if you want a guaranteed mix of colors.

Overall, the Willard & May Mixed Gladiolus Bulbs are a good deal for budget-conscious gardeners who want easy summer flowers. They are best suited for casual gardeners willing to accept some variability in size and color. If consistent color and high-end performance are must-haves, you might look elsewhere. But for a big, cheerful display of gladiolus with minimal effort, these bulbs deliver reasonable value.
