Menyanthes trifoliata 'Mountain Home'

Hello Mr. Bean

One of the great surprises in our bog garden is the survival of the North American native, bog bean, aka: Menyanthes trifoliata. This odd monotypic genus (only a single species), hails from cool parts of North America and Europe, and we assumed had little chance of survival in our hot, humid Southeastern climate. That was

Diplaziopsis pycnocarpa

From the Glade to your Shade

The amazing glade fern, Diplaziopsis pycnocarpa has long been one of our favorite native ferns, but it’s a bit of a loner. This fern, whose native range is from Maine to Louisiana, also has a bit of an identity crisis, formerly being known as Homolasorus pycnocarpus, Diplazium pycnocarpon, Athyrium pycnocarpon, and before that, several other

Molopospermum peleponnesiacum

Moly’s po sperm…Umm

Flowering for the first time this year is one of our favorite umbellifers (carrot family), Molopospermum peleponnesiacum. We grow this for the fernlike foliage, so flower stalks are just an add-on. Molopospermum is a monotypic genus, meaning there is only a single species, which in this case hails from the Alps (France, Italy), and Pyrenees

Trochodendron arailoides

Driving the Wheel Tree Renaissance

One of our favorite evergreen trees is the little-known, Trochodendron aralioides. I first met the wheel tree at the JC Raulston Arboretum back in the 1980s, quickly falling in love with the fascinating foliage, which is arranged at the branch tips, like spokes on a wheel. As the curator of the Arboretum’s Lath House, I

Frosty Pearl

One of our favorite broadleaf shrubs is undoubtedly Orixa japonica ‘Pearl Frost’. Orixa is a monotypic (one species) genus in the citrus (Rutaceae) family, that’s virtually unknown in US gardens. We are particularly enamored with this superb variegated form, brought into the US by plantsman Barry Yinger. Orixa ‘Pearl Frost’ matures at 8′ tall x

Asparagus kissin’ cousin

Ok…raise your hand if you’ve grown Aphyllanthes monspeliensis? This odd, monotypic (only member of the genus) is actually a member of the Asparagus family. Hailing from France south into Northern Africa, Aphyllanthes can be found growing in hot, dry, sandy soils, where it produces an amazing spring show of blue flowers on a 1′ tall
