Early Summer Blooms

The main goal in my perennial garden is continuous blooms throughout the growing seasons. I listed some reliable spring bloomers here.

Next comes the late spring and early summer flowering listed below.

These flowering plants are suitable for cold climate gardens. I’ve listed the general growing zones for plant hardiness, but always check specific plant tags to make sure your selections suit your growing conditions.

1 Poppies (zones 3 to 9)

I took this photo on a garden tour. I love how the color of the shed—blue walls, yellow door, and white trim—go with the green hostas and red poppies.

2 Beard Tongue | Penstemon (zones 3 to 9)

These guys come in some gorgeous jewel tones and attract hummingbirds and bees. Penstemon is native to North America.

3 Allium (zones 3 to 9)

You can find alliums in colors ranging from white to purple. You grow them from bulbs and they will gradually spread. Sometimes the squirrels relocate them, and I’ll find them growing in unexpected places.

Allium Growing Tips

Of all the late spring and early summer blooms in my garden, alliums are the most popular with bees.

After blooming, the seed heads are just as beautiful. I’ve included a photo (below) in the Rose Campion section.

4 Columbine | Aquilegia (zones 3 to 9)

Some gardeners find aquilegia (columbine) to be a bit pesky because it spreads quite readily by seed. Personally, I love it. I always let my columbine go to seed and look forward to new ones every spring.

If you don’t want it to spread (but why?), you can clip off the flowers when they are done blooming.

No-Brainer Seasonal Flower Guide

Perennials are loved by gardeners for their ability to grace a landscape year after year, often growing stronger and more beautiful as they age. But unlike ever-blooming annuals, most perennials have a relatively short bloom season, lasting from a few days to a few weeks. Planting a variety of perennials with staggered bloom times ensures flowers in your yard all season long.

Here are a couple of tips for success when planning your seasonal flowers:

  • Remember to plant perennials with showy foliage or other seasonal attributes so that when the flower burst is finished, attractive leaf color or pattern, seedpods, or texture remains.
  • Increase the volume of plants you use if you want season-long color. Where three or four annuals brighten a bed with nonstop blooms, you may need at least a dozen different perennials to ensure long-lasting color.

Utilize the list below as your seasonal flower guide to help you plan out your seasonal perennials.

Late-Summer Perennials We Love

  • By Deb Wiley

The peak blooms of spring are now gone and the fullest bloom of summer is yet to arrive. We’re in the “lull” in between peak seasonal bloom. Gardens which rely primarily on flowers to achieve color are looking a bit tired as plants start to complain about the near 100 degree temperatures– with hotter yet to come.
There are plenty of native and adapted perennials that are happy to grow and bloom in our arid Utah summers. In this post, we’ll focus primarily on commonly available perennials that are blooming right now, many of which will still be blooming come August. Most of the plants below would be considered “moderate” in terms of water use and all are happiest in sunny conditions. That means you can plant Ozark Sundrops in front of Shasta Daisies and be confident that they’ll happily interact. Any of the 12 perennials below can be mixed and matched in the same planting beds. A high percentage of the featured plants originate from the Midwest prairies and would look even more “at home” if ornamental grasses are thrown into the mix.
Native plants are more xeric than the 12 featured here so we’ll cover those in a separate post. Suffice it to say, we’ve got more interesting native plants than you might imagine. Utah is a fabulous place to garden!
Designer Tip: Foliage
When selecting plants, I use a general rule of thumb that 1 out of every 3 plants should be selected primarily for foliage traits. That doesn’t mean the plant won’t also contribute blooms, just that it’s also attractive when NOT in bloom. Remember that beauty is created through contrast and flowers are just one form of contrast.
