June sees a significant increase in bee activity here in Connecticut. During the past two weeks on my own property the perennial flowers like catmint, yarrow, hyssops, beardtongue (Penstemon spp.) and giant plume flowers are in full bloom. Heuchera and astilbe are or will be blooming. Winterberries, mock orange, shrub dogwoods, and Itea virginica (sweetspire) shrubs are also in full bloom, and the bees are having a field day on all of these. By far, the most pollinator species on my plants are visitng hyssops, catmints, winterberries and  Itea and sea holly. Annuals like lantana and salvias help fill the gap between spring blooms and summer bloomers like Echinacea, Coreopsis, and mountain mints.

I just planted a newer variety of winterberry called ‘Sunsplash’ near two old ‘Red Sprite’ winterberries, and all are teeming with many species of bees and other pollinators. I like the bright yellow contrast to the green leaves of this new winterberry- makes a sparkly, happy addition to the garden. I have the male counterparts of all my winterberries to ensure pollination and later, the optimum berry crop.

Tucked in between the winterberries are a couple of sea hollies- Eryngium planum. These plants have a very interesting stem, bract, leaf and flower color- a chalky blue- purple that seems to change somewhat during the day depending upon the available sunlight. Flowers resemble thistle or teasel in form and shape. Little green sweat bees found the flowers minutes after the plants went in the ground. Many other bees, large and small, visit the flowers throughout the day.

Nepeta spp. catmints bloom for a long period, and can be cut back for rebloom. Although the flowers are small, bees of all kinds visit them, as do skippers and other small butterflies. There are a variety of smaller catmints that can be inserted into the garden that will not crowd out other plants.

Salvias are a great source of nectar for bees and butterflies, and most hang on to flowers until frost. Black and blue, red, and the ‘Rocking’ series are also a huge draw for hummingbirds. A favorite of mine is the salvia ‘Hot Lips’. Flowers are a combination of red, white or half red and half white. Most bloom until frost for added appeal.

A small native shrub, New Jersey tea, attracts pollinators of all types including flower beetles, bees, butterflies and syrphid flies. Flowers are airy clusters of white and are fragrant. The one drawback to this plant is its attraction to deer.

Hyssops of all kinds attract bees and butterflies. The most bees I am seeing is on the Agastache ‘Blue Boa’ (Giant Hyssop). This hyssop blooms earlier than most varieties, and its flower heads are large and puffy. Short-tongued bees enter the flowers, an bumblebees can be spotted with their rear ends and hind feet sticking out of the flowers.

In the wild or in the landscape, Penstemon, hairy beardtongue, is a plus to any pollinator garden. In the wild, large colonies can form, which is useful in reducing travel efforts of our native bees. In the garden, planting quite of few of these plants in a group is very helpful to bees.

Milkweeds are beginning to bloom now, butterfly weed being among the first to flower. Many pollinators and other interesting insect species have affinities toward milkweeds, making them a great addition to gardens and landscapes.

Heuchera and Astilbe are often overlooked as pollinator plants, and these are especially useful in areas with good afternoon shade. Bees are not averse to being in the shade, and there are many plants that will benefit pollinators. Hostas have flowers for a while, and before and after that, foliage is of interest until cold weather arrives.

There are many other plants flowering in June that can supply nectar and pollen for our native butterflies and pollinators. If you have room, trees such as Catalpa and lindens are of great value. A note on this year- perhaps because of cool weather(?), the bloom periods of many plants like the Kpusa dogwoods have seemed to go on forever. And little, if any crabgrass has been seen yet, which may be a good thing for some people.

Check flowers for pollinator activity, and expect that to increase as the weather warms up. It is a satisfying aspect of gardening to know other creatures benefit from your efforts. Bees would send a thank you card, but they are not interested it doing so. Too busy…
