Fuukiran – colored flower forms

In nature Neofinetia falcata occurs mostly as white flowered plants, but some individuals can have purple flushing, sometimes just on the flower’s spur (the downward extended and curved part that contains the nectar) and occasionally this color can extend to most of the flower, in particular the sepals and petals.  Other forms can be found with green flowers, again, mostly in the sepals, petals, and spurs.  No confirmed yellow flowers have been found yet, although many dealers claim to have true wild collected yellow flowered plants.  I’ll speak more about that later.  The discussion here is about some of the more common colored flowered fuukiran.

The first group are the purple flowered forms.  All of these are claimed to be at one time wild collected and nowadays are propagated though division and also from seeds.  One of the most common and easy to flower is Benisuzume. This one clumps very quickly and it is always generous about flowering too.  Its flowers are on the small side and usually are just a pastel pinkish purple.  The lip is totally white.

Shutennou is one of the most famous of the purple flowered forms. It originally was from Shikoku and wild collected plants were slow to grow from division. Plants propagated from seed today are fast growers and clump well. I’ve found it easy to flower, but I don’t get as many spikes as on Benisuzume. An interesting plant from the island of Shikoku is Shikoku Akabana. The only negative thing I can say about this one is that it is slow to clump. Tougen is an older form with lovely curving purple spurs. It seems easy to grow and flower, yet remarkably not well known or grown given its charms.

The sago palm, Cycas revoluta, in Japan

This article is about Japan’s only native cycad, Cycas revoluta, the so called King Sago palm.  Of course, like other cycads it is not a palm at all, but rather a member of a very ancient group of plants that predate all flowering plants and modern conifer trees.  This lovely species is perhaps the most cold resistant of all cycads and yet can be grown in tropical climates as well.  It can grow in either sun or shade, it is able to withstand both monsoonal rains and extended droughts, it responds well to both container culture and open gardens, and for the most part needs little care.  In Japan it is called sotetsu, and has been an important garden plant for centuries here.

Cycas revoluta is native only to Japan’s southern islands and the extreme south end of the southernmost main island, Kyushu, in Kagoshima Prefecture.  It’s habitat is rocky shores where it can be found growing on near vertical rock faces in full sun.  This region is essentially frost free and is classified as a subtropical climate.  Winters average around 10 C (50 F) in the north of its range and 18 C (65 F) in the south.  Winter extremes can go to freezing or even below in Kagoshima, but this is rare, particularly along the seacoast where this species is found.  Summer temperatures throughout its range average nearly 30 C (86 F) with extremes rarely getting above 35 C (95 F) due to the moderating effects of  warm coastal waters.

Rainfall is high with 2000-2200 mm (78-86 inches) falling in an average year.   Most of that falls in the late spring, summer, and fall, particularly during the monsoon season. The summer monsoon starts early on the southern island of Okinawa, in May usually, but is a little later in Kyushu.  This season typically ends in July.  August is often dry, sunny, and hot, but towards its end, typhoons become more and more common and so another peak of moisture comes at this time.  Falls are drier and often sunny, but by December skies grow cloudy, rainfall drops considerably, and temperatures cool down.  Humidity is the one stable element – averaging between 75-80% year round.

Coming from a place like the one just described, you would imagine that this plant doesn’t have much cold tolerance, but you’d be wrong!  This cycad has been grown successfully in the warmer parts of the UK and parts of the southeastern USA that routinely get hard freezes.  This natural ability to withstand cold conditions has made this one of the most versatile cycads for the open garden throughout the world.  In Japan it is commonly seen in parks and next to public buildings, but rarely in private yards.  No doubt this due to the ultimate size these plants can attain, which can mean up to 3 meters or more tall (10+ feet) and with a frond spread nearly as large.  It is grown throughout the warmer parts of Japan far beyond its native range – clear up to central Honshu at least where it requires protection in winter.  In terms of the USDA’s cold hardiness scale, it can withstand zone 8, and the warmer parts of zone 7 if winter protective measures are taken.

Welcome to BotanyBoy

This is an online plant encyclopedia with a particular focus on some of my favorite subjects – orchids and ferns. Also, you’ll notice quite a bit of Japanese flavor since I have resided on Japan’s southernmost main island, Kyushu, for the past 11 years. While interest in plants extends back over my entire life, first kindled by my father in the woodlands of New York State over 4 decades ago, it has recently been strongly shaped by the sheer artistry of Japan’s horticulturalists.  Check out the Botany Boy video channel.

How to grow fuukiran, the basics

Neofinetia falcata is an easily grown orchid.  In nature it grows on trees or sometimes rocks, and is termed epiphytic in habit (literally meaning “a plant growing on the outside of something”).  Therefore, they cannot tolerate being planted in soil, but instead require other composts that remain airy and do not break down quickly.  They also are very resistant to cold in winter compared to most other epiphytic orchids.  They do need a true cool winter rest to flower and grow correctly, but just as important is a long, warm, and moist summer season. Fuukiran, being special forms of N. falcata, respond to the same basic conditions as the typical wild form of the species.

Let’s start with proper planting. The wild forms of Neofinetia falcata, known as fuuran in Japanese, can be grown like they are in nature, that is, mounted to outside trees in appropriate climates or onto tree fern plaques, any nontoxic wood, or for that matter onto rough stone such a pumice.  I grow large ones on inverted clay flower pots very successfully. They can also be grown like their tropical relatives such as Vanda and Ascocentrum, in clay pots or baskets with little compost.  Some people grow them in a typical orchid bark and perlite mix with reasonable success.  As long as the growing medium isn’t allowed to break down too much or stay continually wet, thus insuring healthy roots, they will grow fine using any of these methods.

Naturalized Neofinetia

Fuukiran, being of such high value, are usually handled with more care, especially in Japan, but also by growers worldwide who have learned traditional growing techniques perfected over the centuries.   In short, plants are grown on top of a mound of high quality, long fibered sphagnum moss that is ball shaped and hollow at its core.  This ball of moss sits in a pot that allows for maximum air movement around the roots.  That, I’m afraid is a really tough thing to imagine if you’ve never seen it, so I’ll have to go into detail  about how this ball is made and how to incorporate the plant into it.  Repotting them in this manner should be done in late winter, just before they commence their growth cycle.  If you repot them at other times you can damage growing root tips and delay proper growth during their growing season.  Check out this video to see how to pot them the traditional way:
