A Clivia cross marks mid-season


Known as Clivia Interspecific Group, these crosses between two species of the common houseplant clivia, are often crosses between an autumn blooming species such as C. caulescens, and a spring blooming species, like C. miniata. The autumn blooming species have pendant, slender blossoms with greenish tips to the petals, and the spring blooming C. miniata, which we are all familar with, have larger, wide blossoms. These crosses have a little of both, and are variable. Look for them at plant collector sales, or cross your own ( it's not that hard, and the berries are easy to clean and plant, since the seed is large, looking very much like a macadamia nut).

Clivia are long-lasting, sturdy house plants, and they bloom indoors if you can provide them with a cool, bright room where the daylight will trigger bud formation ( meaning - no lamps near by, nor street lights - these are plants that need to experience the natural progression of day length in the spring, or the shorter day length in autumn). Allowing them to go dry all winter, is incorrect, and will not stimulate these South African plants to bloom. What triggers them is temperature shifts from day to night, and day length. It's the only way that they will know that it is spring, or autumn ( or mid-winter, as in this case!).

Camellia Bowl XLVII

In this month, when it seems we are forced to endure the dreary (thy grumpy Ground Hog, a dead President or two, dirty snow, the impending doom of mud season, and yeah, bowl games), we are reminded that we must remember the hottie ( St. Valentines Day, chocolate, hot cherry pie). But really, there is another reason why we secretly adore Saint Valentines Day, and it has nothing to do with jewelry. We more visual people love it because it is so perfectly pretty - just check out the seasonal candy isle at your local Walmart.  Businesses know that February needs a PR team - plus some designers picking out the perfect tint of periwinkle, magenta, coral and pink - combined with cerise and red - all trying to make this ugliest month (since November), somehow more survivable.  But I am reminded that before there were sweet tarts and chocolate covered cherries, and Jared, there was --- camellias.

Camellias are for old ladies. At least, that's what I used to believe. In the olden times ( like, fifty years ago) camellias were only seen as corsages for church, corsages for Gramma at a wedding, and for, I don't know - sweet tea parties in the south? . But these Chinese trees were once the most cherished if not rarest plants ever grown in containers and in gardens. At one time, they were only grown in the Imperial Palaces of Japan and China, where they were one of the first plants ever cultivated in pots by man, some dating back to the 10th century. Today, they are still not as common as one may think outside of California and the deep south in the US, or in southern Italy and France in Europe.

Here in the north, the camellia is a rare site, for they make horrible house plants, and they are not hardy for outdoor culture. To have any success with camellias, one must have a cold, sunny room with moist air - something that was more common a hundred years ago, but with modern heating systems, an indoor location rarely found in homes today.

Camellias are best grown in a cool, if not cold greenhouse, with buoyant air flow, a day and night shift in temperatures, and with bright winter light. An understory tree in its native eastern Asia ( the mountainous areas of Korea, China and Japan), this smallish tree did have its heyday in North America in the 18th and 19th century, for it was perfectly appointed for the estate conservatory which had wood or coal heat during the day, and chilly nights, or, it was often found in grand, Victorian parlours and homes which had unheated rooms. Camellias thrive in cold, if not near freezing temperatures, able to take frosts down near 15 - 20 degrees F for some time, so they are common landscape plants in areas where winters are more mild ( Oregon, Georgia, southern Europe, England and Japan), but elsewhere, they cannot live.

Camellia societies shows are terrific places to discover the perfect forms to grow. This show, at the Descanso Gardens in California, is held annually near Pasadena. Tables are laid about with small containers, each with a different selection often grouped in threes, fives, or singly. I made my wish list at two of these shows held in February a few few years ago, and then took my list to the nearby Camellia nursery - Nuccio's, where I had a crate packed and sent home on the plane with me. Trying to find camellia's in New England is practically impossible today, while a hundred a fifty years ago, most every greenhouse and florist from New York to Boston, had many trees growing for winter blooms to supply weddings, funerals and corsage work. Camellias are indeed, living heirlooms today, for one can hardly find a blossom anywhere - even in the poshest of New York City florists.

Pitcairnoideae or Deuterocohnia? I still likey.

Botanist's continue to study and reevaluate certain genus, and one of the latest changes happened while no one was looking - don't despair, every ones fav bromeliad Abromeitella is now reclassified as Deuterocohinia - gasp.
I wouldn't let this keep you up at night, it will take years for even serious collectors to rename their plants, to make new plant labels, to learn how to even pronounce Deuterocohinia, and most importantly, for the plant catalogs and nurseries from which one finds these more unusual yet fabulous house plants, to change their plant descriptions. Often by then, the name changes again anyway. For now, most people are still calling this plant Abromeitella.

This tiny, symetrical bromeliad is highly cherished in collections of many cacti and succulent growers, who appreciate symmetry and the over-all form of their plants. Once classified into the sub-Family Pitcairnioideae (pit-cairn-ee-oy’dee-ee) , this is one long-lived relative of the pineapple family, and it gets better with age, forming a nice, tight mound, or bun shape that looks very much like a rock or a mound of moss.

If you are looking for an easy-to-grow house plant that has excellent geometry and form, then I highly recommend searching out a young plant of Abromeitella. There are four species that have this tight growth pattern, all are wonderful and rarely seen ( which also means that they are not common, and not very easy to find). Like any plant, I suggest one begin with a Google search, or, find a friend with a plant who will share a 'pup' with you. These are easy to propagate from cuttings. 

My three plants are still young, only three and four years old from young plants and cuttings, but I have a friend ( Art Scarpa) who has some very large and impressive specimens which win ribbons often at the larger plant shows ( like Philadelphia Flower Show and the New England Spring Flower Show), we call them his 'green sheep'.
