The variegated hardy hibiscus, H. ‘Summer Carnival’ has looked outstanding all summer. This Hans Hansen creation has both variegated leaves and flower buds. We’ve had these in the garden since 2017, and they continue to excel. Moist to wet soils and full sun are ideal, but they handle short term drought just fine. Hardiness is Zone 4a-9b.
Looking great in the gardens this week is our 2021 introduction of Baptisia ‘Blue Bunchkin’ (available again in 2023). Baptisias are North American native perennials and are equally at home in a bone dry site or as a marginal aquatic…as long as they get at least 4-6 hours of sun daily. Hardiness in Zone 4a-9b.
Take a peek inside our baptisia breeding and trial beds with Tony.
Iris ‘Gerald Darby’ is one of those iris that doesn’t even need to flower to be garden worthy. Here it is in our garden this week, emerging with its’ purple leggings. This gem is a North American native hybrid of Iris versicolor and Iris virginica, known as Iris x robusta. This introduction of Iris breeder Gerald Darby was actually named for him after his death by another iris breeder R.H. Coe of England. Iris x robusta ‘Gerald Darby’ is equally at home growing in standing water as it is in typical garden soil. Hardiness is Zone 4a-9b.
Arundo donax ‘Golden Chains’ is looking quite nice in the garden this month. We love this selection of the giant ornamental grass that’s used for making reeds for wind instruments. Arundo ‘Gold Chains’ is much less vigorous than the the typical species, and much easier to fit into smaller gardens. Here’ we’re growing it as a marginal aquatic, where it thrives as well as it does in typical to dry garden soils.
If you have a soggy area or damp soils, don’t drain it! We have marginal aquatic perennial plants for wet soil that are great for landscaping everything from rain gardens to bog gardens. These garden perennials love moist spots and will make you fall in love with perennials that dry soil gardeners only dream of growing. Damp soil plants range from carnivorous plants like sarracenia and bog plants like hymenocallis that need full sun.
