Blossom XXV: Elegance


The Calla lily always feels elegant and exotic.  Its long slender leaves, slender stem, and simple form might have been designed by Coco Chanel for all of their tres chic simplicity.  Until a trip to Oregon two years ago, I assumed they were best found at a high end florist.  But no.  Calla may be grown in any temperate garden as simple perennials.


The Calla growing in every other front garden in the beach communities I visited along the Oregon coast, grew in thick clumps, about 4′ high.  They were already blooming in April of 2015.  I was mesmerized, and determined to find something similar for our own garden.

My search took me first to Plant Delights, which offers two selections of ‘Giant’ Zantedeschia, both hardy in Zones 7-10.  By ‘Giant,’ we mean plants topping out at perhaps 6′ tall.  Like other aroids, Zantedeschia, called Calla lily, grow from a tuber.  And each year the tubers grow larger as the clump spreads.  The clumps I saw in Oregon had clearly been growing for many years.

I began searching out Zanteschia tubers later that year, and have added a few to our collection each spring since.  I’ve learned these are hardy for us and may be left alone year to year to simply grow to their own rhythm.  They are fairly heavy feeders and appreciate good soil, plenty of moisture, abundant sunshine, and a little support.  Their leaves are spectacular, even before and after the blossoms.

We’ve not yet grown any Zantedeschia that reached more than perhaps 3′ tall.  But I have noticed our clumps, left in the garden last fall, bulking up this year.  In fact, I dug up several clumps which grew in pots last summer, and moved them out into the garden in late October.  What a welcome sight when they broke ground this spring!

These South African natives adapt well to our climate.  They aren’t invasive, so far as I know.


Zantedeschia albomaculata, with white spots on its dark leaves, prefers moist soil and will even grow in a pot partially submerged in a bog garden or shallow pond.  It will grow to about 24″.  Zantedeschia aethiopica, with solid green leaves, grows a little taller.  And it also enjoys moist soil.  Although we normally think of Calla lily as a white flower, there are many named hybrids with flowers of various colors, including some of very dark maroon or purple.


Zantedeschia emerging in early May. The first leaf tips emerged in late March.


Zantedeschia grow well in pots or planted directly in the ground.  If you live north of Zone 7, you can bring the pots in when your weather turns, and keep them going indoors as house plants.  In fact, our local Trader Joe’s has proven a reliable source of potted Callas with bright flowers, ready for your patio or to be gifted to a friend on a special occasion.


If you are looking for something elegant, simple, and different for your garden this year, you might try growing Calla lilies.  Deer leave these leaves alone.  Callas have crystals in their leaves, like other Aroids, which cause them to irritate an animal’s mouth.  Given sufficient moisture and sun, these elegant, yet easy perennials will happily fill your garden with beauty.

where dirt used to be.”

Like other Aroids, the Zantedeschia ‘blossom’ consists of a spadix, surrounded by a modified leaf called a spathe. Seeds form in tiny berries along the spadix after the spathe falls away. This plant is very much like the Arum italicum, and the two plants may be grown side by side to give a full year’s worth of foliage and a longer season of flowers.

  1. Nothing says ‘elegant’ like a vase of calla lilies. Someday you’ll have enough to do that!
