A Melting Pot of Carex

We’ve published blogs about a number of carex from our rather large collection (108 species) several times this year, but here are a few more that look great here in early December. We have been fortunate to be able to collect members of this amazing genus from around the world, all of which now reside happily here at JLBG. As you can imagine, the majority of our collections are US native species, but just like with Homo sapiens, we value diversity and consequently don’t profile or discriminate based on ethnicity or origin.

The first is the US native Carex austrolucorum. This is Jeremy’s collection, named Carex ‘Tennessee Mop Top’.,

Carex gentilis ‘Yushan’ is our collection from Taiwan, and the only fall-flowering carex we know. Duke Gardens has made stunning use of this in their magnificent Asian garden expansion.

Carex ‘Silk Tassel’ is a stunning selection of the Japanese Carex morrowii var. temnolepis, brought to the US back in the 1970s by plantsman Barry Yinger. We still view this as one of the finest carex we’ve ever grown. While it grows great in shade, it truly excels in full sun, where its narrow variegated leaves appear silver.

Willow the Wisp

Carex ‘Willow the Wisp’ is one of Zac Hill’s amazing collections from nearby Willow Springs, NC. This is a widespread native, naturally ranging from Michigan south to Florida and west to Texas. We love the appearance of a head of green hair…minus the head. In the wild, this selection of Carex leptalea var. harperi thrives in wet mucky swamps, like the story of Will-o’-the Wisp. We planted this in similar conditions in a seep at JLBG, where it has made this stunning specimen. Any plant that looks this good in October is undoubtedly destined for a future catalog.

Blue mulch

There is a “growing” trend toward using groundcovers to reduce the need for bark mulch in gardens. As with any trend, there is a time and place where it is appropriate, and other times when it is not. One plant that we absolutely love for that purpose is the evergreen Carex flacca ‘Mini’. This blue-foliaged sedge is a Mediterranean native marsh grass that spreads very slowly, so it is not a problem in overrunning other plants in the bed, as long as they aren’t placed too close. These pictured below were planted six years ago on 1′ centers, and are just now knitting together.

We have studied a few reports of this sedge being invasive in parts of the northeast US, but our trials have shown quite the opposite, with nary a seedling in over six years. We can find no scientific research that shows this sedge qualifies as being invasive using any commonly recognized definitions of an invasive plant. Our skepticism of these reports comes because some of the ridiculous listings that appear on invasive species lists, which have no scientific basis. Our favorite invasive faux pas was a listing a couple of years ago of the genus Bambusa on a state invasive list. Never mind the plant is a strict clumper and only flowers once every 100 years. Winter hardiness is Zone 4-9.

Colors and Textures

Here’s a recent image from JLBG, giving an idea of what’s possible when being thoughtful of textures and colors when planting. Plants include Iris x hollandica ‘Red Ember’, Heuchera ‘Silver Scrolls’, Carex ‘Bonnie and Clyde’, Thelypteris kunthii, and Juniperus chinensis ‘Parsonii’.

Japanese Princess Sedge

Carex conica ‘Hime’ has been in horticultural commerce for many decades, and remains a superb woodland garden sedge. The evergreen species Carex conica is native throughout Japan, where it occurs in woodland conditions. This variegated selection that goes by an array of names such as ‘Snowline’ and ‘Marginata’, but Carex conica ‘Hime’, which translates to “princess” seems to the the correct cultivar name. The tight 10″ tall x 20″ wide clumps of narrow white-edged leaves are topped with this fascinating floral show for us in early March. In 35 years of growing this, we have yet to see a single garden seedling.

A Rolling Stone gathers no moss, but a stationary stone…

Indeed the old proverb about a rolling stone is correct, but a stationary stone, especially in the water, gathers all kinds of amazing things. This rock in one of our garden streams has not only gathered moss, but several young maple trees, a carex, a couple of sanguinaria (bloodroot), and a handful of various ferns. Isn’t nature just grand if you stop long enough to pay attention.

Color mixing

Here’s a fun combination at JLBG this week with Heuchera ‘Smoke and Mirrors’, Iris x hollandica ‘Red Embers’, and Carex retroflexa ‘Bonnie and Clyde’. So many plants, so many fun combinations.

Golden Flowering Moment

Just captured the wonderful gold-foliaged Carex ‘Everillo’ in full flower by our front grotto waterfall…what a great landscape plant!

Swept Away

Sweeping sedge is in full flower in the garden today. The North American native (Canada south to Florida and west to Texas) Carex bromoides swept us off our feet! This delightful small evergreen sedge forms a 6″ tall x 30″ wide, delicate-textured patch of green hair-like foliage. Although it prefers moist to mucky wet soil, ours has fared beautifully in well ammended compost. Carex bromoides is a favorite meal food for a number of butterfly and skipper caterpillars, wood ducks, grouse, and several songbirds, which in turn eliminates any need for fertilizers. We think you’ll really love Carex bromoides, either as a solitary specimen or in mass.

Logging in…the old fashioned way

When we re-worked one of our recirculating water capture streams a couple of years ago, our grounds supervisor, Jeremy Schmidt, who coordinated the project, wanted to include an old buried log that he had found when excavating another part of the property. It took quite a few staff members to hand carry it and place it across the man-made creek where it resides today. Because it was hollow on one side, we filled it full of planting media and voila…a naturalistic vignette resulted. Here it is this week in the winter garden with several clumps of Carex oshimensis to echo the flow of the water.

Winter Structure for Your Garden! Everillo!!

Evergreen (and evergold) perennials are a great addition to your garden. They add texture, color, and form during the winter months when many perennials go dormant. Carex ‘Everillo’ not only adds texture and form with its thin leaves and weeping habit, but it also brightens woodland or lightly shaded garden with its bright gold color. Everillo also works well in planters paired with seasonal color such as pansies.

Carex ‘Everillo’ holds its color brightest with some morning sun and pairs nicely with blue agaves and other plants with colorful foliage.

Here is a picture of Carex ‘Everillo’ in our sales house ready to ship to you. We have extended our shipping until December 9, and you can also pick up at the Nursery, so you still have a chance to light up your garden or mixed planters for the holidays.

Carex specialist Pat Fitzgerald visits PDN/JLBG

We were delighted this week to welcome Irish nurseryman/marketer Pat Fitzgerald.  This was the first time we’d met in person, although we’ve corresponded on-line for years. We had a wonderful time walking through the gardens and sharing our excitement about new plants on the horizon.  Pat is best known for his amazing line of carex that he’s developed, with more in the pipeline.  Here are a few you’ll see if you visit during our final two Summer Open Nursery and Garden days today (Saturday 8-5), and tomorrow (Sunday 1-5).
