Garden Bloggers Bloom Day-June 15th

Welcome to Plant Exchange blog, USDA Zone 4-5a on the Northern Plains. After a cool spring, we are having temperatures climbing to 90 degrees F and dry conditions lately. We’re excited to show you plants in bloom today.

Just in time for Pollinator Week, our Northern Catalpa is in full bloom, attracting various kinds of bees. A local hummingbird buzzes by often. The air among the blossoms is lightly fragrant. The flowers are open day and night for pollinators. We also appreciate perennials and annuals for attracting insects, but a whole tree in flower supplies much nectar and pollen in the transition from spring to summer.

Large leaves are heart-shaped in the USDA Zone 4-8 Northern Catalpa. The introduced catalpa is called a medium to fast-growing tree, reaching 40 ft in height or more. It grows best in at least 4 hours of full sun and then part shade. The tree tolerates a wide range of soils, including clay and alkaline, found in some areas here.


Common Milkweed has its first bloom in the clump of plants. The single head is already drawing small insects. Perhaps we’ll see a few Monarch butterflies soon.

Clematis is beginning to bloom. When the vine has damp soil and some direct sun, it elongates, these spring days.

Yarrow is a color stand-out when displayed in mass. This variety is shorter than the native form and pairs well with Bee Balm and catmint, also in bloom.

See what's in bloom today!

It’s an adventure to discover the flowers around us as they open in their stages of the season. Thanks for visiting Plant Exchange Blog. Do come back again!

If you’d like to see what’s in bloom in Indiana, the link below is to May Dreams Gardens, where Carol will show you flowers there. At the bottom of her June 15th post, see the list of other garden bloggers waiting to show you their gardens across the United States and in other countries. Here’s the link:

  1. The first picture is rad! Catalpa, although not truly naturalized, self sows around here. I do not even know if it is the northern or southern catalpa, but suspect that it is the northern catalpa.
