More Top Performers
SWEET CAROLINE MEDUSA™ BLACK IPOMOEA

The mounded form of Medusa Black really showed off in the ground trials with foliage that swayed in the summer breezes. The palm shaped leaves didn’t flag and carried that dense habit both in containers and across mass landscape plantings.
SOUTHERN BLAZE™ BRIGHT PINK
Lucas Greenhouse

Known for its love of summer heat, we have seen strong trials from east to west and north to south looking phenomenal, allowing this unique offering to expand its application range. The tidy habit has showcased itself in containers and in the ground with other Southern Blaze™ varieties. Its flower color held true all summer long, providing that eye-catching color you can spot across the garden.
