Silver Moon Fern

We don’t know how many of you have noticed this in the JLBG garden during open house, but this special gem is from a Chinese spore collection by JC Raulston Arboretum director, Mark Weathington. Now that it’s large enough, we have sown spores so we can work with JCRA to introduce this gem to the public.

Polystichum luctosum ‘Silver Moon’

Holy Giant Holly Fern

Cyrtomium macrophyllum is looking particularly fabulous this year. This is a little-grown holly fern with a wide range from India to Southeastern China that can be found at elevations from 2,500-8,000′. The bold textured fronds arch outward to make a 2′ tall x 2′ wide clump that is semi-evergreen in most winters. It seems as if we will get good spore set this year, which may mean another offering since the last time PDN had it to share in 2003.

Celebrate Plasticity

We live in an age where many plastic products are vilified, but every now and then, we find a reason to embrace the texture of plastic. Such was the case in 2008, when we visited The Missouri Botanic Garden. Walking through one of their greenhouse, I spotted an odd holly fern, planted in the middle of a large mass of Cyrtomium falcatum. The foliage appeared much thicker and more glossy than any of the other plants. The staff was kind enough to share a piece, which we subsequently named Cyrtomium ‘Plasticity’. We theorize it is probably a ploidy mutant with an extra set of chromosomes that would account for the extra thickness and glossiness. Here is a photo from the gardens this week, where it has become a favorite.

Upside down Spider Fern

Arachnioides standishii is one of our favorite garden ferns. This particular collection comes from Japan’s Mt. Daisen. The common name is Upside down fern since the leaves appear to be attached inverted. Production is always challenging since spore don’t ripen until after Christmas. The foliage remains evergreen until temps drop below 10 degrees F. Hardiness is Zone 4-8.

Another Giant Monster

A few years ago, we introduced one of our Japanese painted fern sporlings of particularly giant proportions as Athyrium ‘Godzilla’. Recently, we found ourselves in search of another giant monster name for our new hybrid of Osmunda regalis (US) and Osmunda japonica (Japan). We settled on Osmunda x japalis ‘King Kong’ for this 7′ tall giant that we hope to one day share with gardeners around the world. For now, however, it remains a single, rather impressive clump in the gardens here at JLBG.

With Fronds like these, who needs anemones?

The rare Dryopteris x australis is looking superb in the garden this week. This Southeast native, naturally-occurring hybrid will grow in sun or shade and in wet or average soils. Despite its deep southern roots, it’s fine outdoors in Zone 5a. 4′ tall..pretty amazing!

Athyrium ‘Ghost’ fern

Athyrium Ghost6

I just took this photo of the Ghost fern on our patio…can’t imagine a garden without this lovely deer-resistant perennial.  Light shade or even a few hours of sun if the soil is kept moist.

Painted ferns for the garden

Athyrium Godzilla3

Here are a couple of fern images from the garden yesterday.  First is our giant painted fern, Athyrium ‘Godzilla’, which can reach 6′ wide x 3′ tall.  To avoid chlorophyll shed in the garden, it’s best planted a far distance from Hosta ‘Mothra’ or Hosta ‘Rhodan’.

Athyrium nipponicum Burgundy Lace2Here is the lovely Athyrium nipponicum ‘Burgandy Lace‘..hard to beat this color in the spring garden.

 

New Ferns for 2015

Athyrium niponicum Thrill Seaker HH Clone C (63814).cc

For 2015, Plant Delights is pleased to introduce several new ferns from our trial program.  Athyrium niponicum ‘Thrill Seeker’ is one of two dwarf compact crested Japanese painted fern selections from a five year joint effort between us and our friend Hans Hansen of Walters Gardens.

Athyrium niponicum Joy Ride PDN 011 (63813).cc

The second of these crested selections is Athyrium ‘Joy Ride’…quite distinct from Athyrium ‘Thrill Seeker’ when seen side by side.

Pronephrium pengiana2 (63935).cc

Another unique fern that hasn’t been offered before is the 5′ tall, prehistoric looking Pronephrium penangianumThis amazing fern has been fabulous in our trials, but we doubt it will tolerate winters much colder than 0 degrees F.
