What’s Growing On – July 2018

The high temperatures and humidity in July make for harsh conditions for many plants, along with insect and disease pressure, but there are many plants that are excellent performers that bloom and thrive during the summer swelter.

Butterfly bush

Buddleia species are excellent performers this time of year, putting on an extravagant number of blooms that pollinators love. These shrubs bloom on new wood and come in a variety of mature sizes, from 3 to 12 feet, and bloom colors range from white, yellow, pink, purple, and red.

Here are a couple of standout Buddleia in our collection:

Buddleia x Lo & Behold® 'Purple Haze' (Located at the Spillway and several other locations)

This heat and drought tolerant dwarf butterfly bush has fragrant purple-blue flowers from mid-summer to frost. Sterile flowers mean it will not spread by seed and its ability to rebloom without deadheading makes it an excellent low maintenance shrub. It attracts butterflies and hummingbirds but not deer.

Roses

Roses are one of the oldest ornamental plants in cultivation, but they often get a finicky reputation because of the many pests and diseases that attack them. While no rose is immune to everything, there are many new varieties of landscape roses that feature excellent disease resistance to the most common problems. Two standouts from the Drift® series that are new to our collection include:

Rosa x Coral Drift® ‘Meidriflora’ (Located by the Conservatory doors)

This low-maintenance, cold hardy groundcover rose has glossy dark green foliage and excellent disease resistance. It’s low spreading habit and vigorous coral-colored flowers from spring to frost make it a great choice in locations that need low vegetation and lots of color. All roses require full sun and well drained soil.

Rosa x Popcorn Drift® 'Novarospop' (Located on the Spillway at the north end of Lake Lonnie)

This low-growing rose has glossy dark green foliage with good disease resistance on a vigorous, hardy, carefree shrub and abundant soft yellow re-blooming flowers that fade to cream white without deadheading. It performs well in the heat as long as it gets weekly watering and full sun.
