Friday Foliage: Curly Leaves

November 30, 2012

UPDATE: I have gotten a lot of inquiries lately about the availability of the South African spiral-leaved bulbs including Trachyandra and Albuca. While I do have a few of these specimens in my personal collection, I do not grow or sell them because they are extremely labor intensive to propagate and take many years to reach flowering size. You can regularly find specimens from various sellers on eBay, which is where I got mine, but they often command high prices, so be warned! If you are feeling exceptionally skilled, you can try your hand at growing these plants from seeds although, as mentioned, it will be years before you have a mature, flowering plant. Try here or here for seeds, which often sell out quickly.

Hope that helps and thanks for visiting!


When I wrote last week about what it is I love about plants, it all boiled down to the fact that plants are diverse. They come in every color, size and shape. With that in mind, I’d like to introduce a new feature called Friday Flowers & Foliage, where each week I choose a theme and explore various examples throughout the plant kingdom. For our kick-off week, I’ve chosen to examine plants whose foliage exhibits a peculiar characteristic: that is, the tendency to twirl. I’ve had a love-hate relationship with my own head of curls since the beginning, but there’s no arguing these spiral specimens are something to marvel at.

Juncus effusus 'Spiralis'Juncus effusus 'Spiralis'

Juncus effusus, also known as corkscrew rush, is a water-loving perennial and makes a good container or houseplant. There are a number of cultivars whose stems form beautiful, tight corkscrews including ‘Unicorn’, ‘Spiralis’, ‘Curly Wurly’ ‘Twisted Arrows’ and ‘Big Twist,’ in addition to at least two variegated varieties: ‘Lemon Twist’ and ‘Frenzy’. If, after reading this post, you decide to give your garden a little twist, Juncus will be the plant that is easiest to come by and to grow.

Albuca namaquensisAlbuca spiralis

Albuca sp. are caudiciform members of the Asparagaceae family, native to South Africa (all the weirdest plants come from South Africa, don’t they?). These winter-growing bulbs produce small, bell-shaped flowers, but it’s the unusual foliage of some of their members that sets them apart. A. spiralis and A. namaquensis both produce exotic, curled leaves, wound more tightly at their tips rather than along their length. The two species are very similar in appearance, but there are a few distinct differences. Most notably, the flowers of A. spiralis produce a sweet, buttery vanilla scent, while the leaves of A. namaquensis are covered with fine hairs. A third species, A. concordiana, also produces this strange foliage. Note that the degree of curling varies between individuals and appears to be at least in part related to environment, be it light, heat or something else all together.

Albuca concordianaTrachyandra sp.

Trachyandra is a genus of plants similar to Albuca, both bulbs belonging to the order Asparagales and both native to South Africa. And, like Albuca, some Trachyandra produce transfixingly tortuous foliage, like the unidentified species pictured above.

Cyrtanthus spiralisGethyllis linearis

Yet more natives to the Eastern Cape of South Africa, Cyrtanthus smithiae, C. helictus and C. spiralis (above left) are relatives of Albuca and Trachyandra who produce beautiful, tubular amaryllis-esque flowers and an interesting array of twisted foliage. And speaking of amaryllis,  Gethyllis linearis (above right) produces large, fragrant white flowers just in time for Christmas. True plant geeks, how about growing one of these bulbs for your table this year? You’re guaranteed to have the rarest, most interesting centerpiece around.

It has been suggested that cases of naturally curled leaves are an adaptation in response to hot climates, where having a spiral leaf reduces surface area that is exposed to the sun. Whatever the reason for them, though, these species are truly unique and highly sought-after by collectors. And for the rest of us, they’re pretty cool, too.

Hi,

I really want to get hold of one of the plants you have identified as a Trachyandra. Unfortunately web searchers are not helping me ID the exact varieties you have shown and they are the ones I want. Could you give me any more detail on which they actually are?

Thanks so much,
Kathy

Hi Kathy,

the closest I could find is either a Tachyandra tortilis or a Tachyandra revoluta. Definitely a cool plant!

Also a plant lover and while walking in the wetlands of Northwester Alberta this summer photographed some wild purple ladyslippers about 2 inches tall in my 40 years living in this area much of them in the mountains and foothills I never seen these before although older trappers have said they are edible .I am wondering how to upload these and have it and some other rarely seen especially in bloom to have them documented and recorded

    Hi, Corinna. I would contact a local native orchid authority for assistance. Try the Canadian Native Orchid Congress, University of Alberta or the Orchid Society at the Royal Botanical Garden. Best of luck!

The one I’m interested in is “Trachyandra sp” acording to Mr. Google, but I cannot seem to find more than ONE pic of such species in order to confirm this. Also, I don’t know if “sp” stands for something longer. Can anyone give me a hand here? I want to try to get the one at the right (from the two trachyandra pics).

Thanks.

    Hi there. “Sp” in a plant’s name stands simply for “species.” This means that the exact species is unknown. In this particular case, the photo of the Trachyandra on the right is of a plant grown by a collector in Southern California. According to him, “I know the grower and he has never offered any for purchase. You might be able to find seed from S. Africa or Mesa Gardens in Arizona.” He claims to never have seen another one. Indeed, this may be the only plant of its kind in the world – it is not unheard of for one single plant to exhibit traits entirely different from all other members of it’s species. Hope that helps!

There are cactus sellers on eBay that I have seen selling the albuca sp but I have not found the trachcandra as of yet. Try TeeDee cactus they are on eBay and also have a regular website. I have done business with them in the past and they sell a very quality product. Lots of unusual things and cristata forms. Some of there 4 inch pots have gone for well over $30 though especially if it’s a cristata form or rare species.

    Hello, Virginia! That plant is called corkscrew rush, or Juncus effusus ‘Curly Wurly.’ Thanks for reading!
