If you love flowers and want continuous blooms in your garden, this is for you. This handy, printable chart lists popular, flowering perennials, and their bloom times through the seasons. It also provides preferred sun/shade conditions and general growing zones.

Choosing Plants for Continuous Blooms

Greetings, fellow flower fans! I can never have enough blooms in my garden. Please use this list as a starting point for filling your garden with long-lasting flowering plants throughout the growing seasons.

I am in southwestern Ontario, Canada (zone 6), and these plants are available at local garden nurseries. Most are hardy for zones 4 to 8. If you need to look up your zone, see the links below.

I can’t list the thousands of flowering plants available but this provides a good sample.

Wait! Before You Plant…

Be sure any plants you choose:

Are recommended for your plant hardiness zone.
Are not invasive in your area.
Are suitable for your growing conditions including sun, soil, water, and wind.
Contribute to biodiversity by providing food, nectar, or habitat for wildlife.
Are not too big for the space available when they reach maturity.

Avoid Invasive Species

Before you choose plants, it’s important to learn about invasive species in your area and avoid them.

Sometimes invasive plants are sold at nurseries so it’s best to find your local conversation authority, or invasive species monitor, or similar agency, and rely on their recommendations and warnings.

Read Plant Tags

This list is generalized. There are so many plant species sold for home gardens, and many derivatives (cultivars, hybrids, related species).

Each may have its own preferences so it’s best to check the information on plant tags and use that as your guide.
You want to follow the planting advice (sun, soil type, location, drainage) and note when and how long the blooms should last.
Also, if you’re buying a plant when it’s in bloom, keep in mind that it may have been coaxed by greenhouse conditions. The plant will need time to adapt to your garden and find its natural bloom time the following year.

Experience

Finally, if you avoid invasives, read tags, and follow good organic gardening practices, what happens in your garden is your best reference for future choices.

Micro-climates within a garden with variations in light, water, and soil can all alter the life cycle of plants.

I like to take photos and jot down notes throughout the blooming seasons for future planting decisions.
