Fall Farfugiums

One of our favorite fall woodland plants is a member of the Aster family, belonging to the genus farfugium. Farfugiums have long had a bit of an identity crisis, as they were originally named in 1767 by Linnaeus as Tussilago japonicum. In 1768, the same plant was also published as Arnica tussilaginea. Then, in 1784, it was moved to the genus, senecio, and became Senecio japonicus.

Later in 1891, it was renamed again, this time as Senecio tussilagineus. It remained in the genus senecio until 1904, when it moved to the genus Ligularia, and became Ligularia tussilaginea. Here it remained until 1939, when it became Farfugium tussilagineum, but corrected the same year to match Linnaeus’s original epithet, resulting in Farfugium japonicum, which it remains today.

Below is our plant of the typical species, Farfugium japonicum in flower at JLBG this week. Through the decades, we have been collecting an array of other forms. Light open shade or a tiny bit of morning sun and average to slightly moist soils produce the best results.

Farfugium ‘Roundabout Fall’ is our selection of a hybrid with our Taiwanese collection Farfugium japonicum var. formosanum and the typical form. We like the smaller, thick, rounded leaf shape.

Farfugium ‘Jagged Edge’ is another upcoming JLBG/PDN introduction, scheduled for a 2023 release. It forms one of the larger clumps of any farfugium cultivars we’ve grown.

Farfugium ‘Bashi Ogi’ is the only cultivar we know of Farfugium japoncium var. luchuense. This rare variety hails from Japan’s southern Ryuku Islands of Okinawa and Kagoshima. It differs in appearance by being a much smaller plant with leaves which are wider than tall. Here is our plant flowering now here at JLBG.

For 2022, Plant Delights will introduce JLBG’s first selection of Farfugium japonicum var. luchuense, that we’ve named Farfugium ‘Sweet Spot’. It’s a miniature seed selection from the above Farfugium ‘Bashi Ogi’, that only gets a few inches tall, so will make a great house plant, where it isn’t winter hardy.

Bamboo Ferns

Another genus of ferns that we just adore are the bamboo ferns of the genus coniogramme. We’ve grown these amazing gems for two decades, and after all that time are still in love. Although these woodland ferns are deciduous, they are tardily so, so they still look quite fresh into mid-November. Here are a couple of favorites, photographed this week.

At the top is the texturally fascinating Coniogramme intermedia ‘Shishi’ from Japan, and below this is our 2006 introduction of the Chinense native Coniogramme emeiensis ‘Golden Zebra’. We rate both of these as winter hardy from Zone 7b and warmer.

If you think you know arums…

Many gardeners are familiar with or have grown arum…mostly forms of the widespread Arum italicum, but few have grown the blingy gem of the genus, Arum pictum var. sagittitifolium. We are thankful to have this amazing collection from an Alan Galloway expedition to Majorca, Spain. Sadly, this species isn’t nearly as winter hardy (Zone 7b and warmer) as Arum italicum and we have never been able to coax it to set seed.

Podocarpus ‘Miu’

We have been very impressed with this stunning new selection of Podocarpus from Japanese nurseryman, Yoshio Sato. Podocarpus ‘Miu’ is a wonderfully variegated selection that has shown a good dense habit, great coloration, and no burning in full sun.

Since so many Americans purchase plants based on the name, and Japanese cultivar names make plants a very difficult sell in the US, the US marketing folks sell this as Roman Candle podocarpus. No matter what you call it, it’s a heckuva plant. Hardiness is Zone 7b and warmer. The marketing folks say this will mature at 15′ tall x 4′ wide, but the in the patent, the originator says it matures at 50′ tall x 25′ wide. Hmmm…that’s quite a discrepancy. Sounds like someone is fibbing.

Mamba Combo

Every day as we take the short drive home, we’re greeted with this combination of Chamaecyparis obtusa ‘Fernspray Gold’ and a new black elephant ear. We encourage people to be more conscious of textures, forms, and colors in the garden, and to notice how plant placement can be used to create such really pleasing moments.

Sunrise over Maui

Here’s a recent image of the amazing Colocasia esculenta ‘Maui Sunrise’, still looking great in late October! Moist, rich soils and full sun are the key for your plants to look this spectacular! Winter hardiness is Zone 7b and warmer.

It ain’t worth a thing if it ain’t got that bling!

Apologies for commandeering the famed Duke Ellington line, but it seems appropriate for the new Colocasia ‘Waikiki’.

When we first met Hawaii’s John Cho in 2003, we knew some special elephant ears would be the result of our collaboration, but it was hard to imagine something like the seriously tricked-out Colocasia ‘Waikiki’. Almost every year, John, who has now retired, but is still actively breeding elephant ears, travels to JLBG to evaluate his new hybrids at our in-ground trials and make future introduction decisions. There are some seriously amazing new selections starting down the introduction pipeline.

Colocasia ‘Waikiki’ will be released from Plant Delights Nursery on January 1, so if you like this, mark you calendars and stay tuned to the website.

Blonde Envy and More

I can’t speak to the truth that blondes have more fun, but on behalf of gardeners who grow blondes (gold leaf plants), we certainly have more fun when they’re around. One of our horticultural holy grails has always been a gold leaf elderberry we can actually grow. The horticultural market is dominated by northern cold climate selections of colored-leaf elderberries, which refuse to survive our hot, humid summers.

I can’t tell you how excited we were a couple of years ago to learn of a Keith Mearns discovery of a wild elderberry near Columbia, SC with beautiful golden foliage, Sambucus canadensis ‘Blonde Envy’. Although it took us a while to track one down (Keith says that less than a dozen exist in the world currently), it is now performing beautifully in a prize spot at JLBG. We’ve turned our Plant Delights propagators loose in the hope we can have enough to share in the 2023 Plant Delights spring catalog.

Just prior to the pandemic, we were plant collecting in UK nurseries, and made a stop at the always amazing Cotswold Garden Flowers. Founder Bob Brown’s son, Edmund, had taken up elderberry breeding, and now held the National Sambucus collection. We were able to bring back a couple of his complex hybrid introductions to trial, and to our shock, both are thriving in our summers. Here is a photo of our 2 year-old clump of Sambucus ‘Chocolate Marzipan’ in the garden. Finally, sambucus envy will be over for southern gardeners.

Freckled Beauty

There are several freckled/variegated selections of beauty berry (callicarpa) on the market, but virtually all are variegated forms of Asian species. We were excited to learn that plantsman Ted Stephens of Nurseries Caroliniana had found a speckled form of the native Callicarpa americana on his property in South Carolina. Our garden plant of his C. ‘Carolina Sunrise’ was interesting, but not spectacular. So, we grew quite a few from seed, knowing that the variegation would be heritable, and those finalists which remain in our evaluation area today are far nicer than the original. Here is one of our finalist selections in the garden this week.

Casting about

Just snapped this photo of Aspidistra minutiflora ‘Leopard’…one of our favorite cast iron plants. Although it isn’t really winter hardy here in Zone 7b, it makes one heck of a tough house plant.
