Effervescent Perovskia, the Perfect Perennial

Capturing the shimmer on this plant eludes most photographers. You will have to grow it to experience the shimmer. This photo is supplied by Lotus Greenhouses. Click on the image to visit their site.

This is the champagne of all perennials. It literally shimmers all summer long. When fully opened, the flowers are lavender blue and brilliant in the sunshine. In bloom, this plant looks like a majestic silver-blue cloud; a veritable purple haze!

Perovskia grows into a multi-stemmed clump with flower panicles at the end of each stem.The finely-cut silvery grey-green foliage is intensely aromatic all season long. In the early spring its woody stems need to be cut down to 6 inches from the ground. It can also be trimmed in the fall but then one would lose the winter interest that the spent flowers offer.

This perennial is easy care and does not like to be moved or divided. It will grow to 4 feet tall and 3 feet wide, is happy in zones 5a to 9b, loves full sun and above all, adds rich character to the garden from July until fall. Heat, drought or humidity will not affect the performance or the beauty of this versatile perennial. Use it as a foil for other plants, especially pink rose bushes. Plant the annual verbena bonariensis in front of Perovskia and the combination will take your breathe away.

Perovskia is a great plant and one of our favorites. It fares very well in our dry clay dirt.
