A Heavenly Landscape with Angel™ Altheas

Author: Briana Johnson   | October 23, 2012

An angel in the garden, these new selections of Althea are more compact and more prolific bloomers than their industry counterparts. Angel™ Altheas are medium-sized, upright, well-branched shrubs that produce an abundance of large, single flowers in late summer.

Blue Angel™ features rich blue flowers with a red eye in late summer, and though similar to the familiar Blue Bird Althea, breeder Dr. Sam McFadden says Blue Angel™ is a lighter, clearer blue and a more prolific bloomer. Blue Angel™ matures at 4 to 6 feet tall.


White Angel™ features large, creamy white flowers in late summer, and though similar to the familiar Diana Althea, breeder Dr. Sam McFadden says White Angel™ is a more prolific bloomer. White Angel™ matures at 4 to 6 feet tall.


Pink Angel™ features large, pink flowers with a red eye in late summer and has a slightly larger habit than the other two Altheas in the series. Pink Angel™ matures at 6 to 8 feet tall, but a bit of pruning in early spring will promote new growth on all 3 varieties since Angel™ Altheas bloom on new wood. Late winter pruning can also be done to keep these shrubs to a smaller size. This also will increase bloom size the following spring.


These vigorous growing plants are easy to grow and tolerate a wide variety of soil types and moistures conditions. They make a beautiful addition to any garden as an accent plant or a border. Angel™ Altheas can withstand winter temperatures of -20 degrees to -10 degrees Fahrenheit in USDA Zone 5.
