We're not sure who the real Ms. Clarkson is/was, but she should be proud to be the namesake of such a great plant. When we began propagating about 10 varieties of Hardy Garden Mums in 2024, this variety proved to be the latest blooming. From November through much of December, this variety was bursting with yellow button-like flowers. A much brighter, more highly saturated yellow than 'Gethsemane Moonlight'. *
