Missed Sunset
Daylight goes quickly this time of year. Last night I grabbed the camera, thinking I’d catch sunset from the roof deck. But thirty seconds later the sun vanished into this sticky cloudbank settled on the water. So, if by “sunset” you mean watching the sun do a slow swan dive into the drink, I missed it.
My weekend reading has been Annie Proulx’s amazing novel, The Shipping News. The book vibrates with a sense of place (Newfoundland) and has descriptions more vivid than the things themselves. Early in it she describes a sunset as “a flock of birds on fire.” My sunset was nothing like that, but still worth the haul up to the deck.

Summer
While I was up there I snapped this shot of the progress of the trio of new plants that I put up there in August, Euphorbia cotinifolia, Kalanchoe prolifera, and Lomandra longifolia. The euphorbia has survived the occasional watering lapses and is coloring up this gorgeous wine red color.

The kalanchoe is beginning to put up its bloom spikes for the winter and is showing an intensification of the red color on the margins of its leaves.
And the lomandra looks like it did in August, only bigger.
I was hoping for a container planting that had seasonal interest–something other than living versions of plastic plants that looked the same year-round. So far I’m pleased.

Galvezia juncea
Last month I decided those three plants needed some company, and so they now have a new resident nearby. This is Galvezia juncea ‘Gran Cañon’, Baja bush snapdragon. It’s green and architectural right now. But soon it should small scarlet tubular flowers to coax some hummingbirds up to the deck. With a big selection of nectar-rich salvias down below, however, the hummers might be a hard crowd to motivate.
No sounds of birds up on the deck, only the sound of the sunset…

The roof garden now has three plants I’ve never grown before. I tried to pick plants that were tough sun-lovers that required almost no attention and not much water. While I don’t like to write about plants I don’t have any experience with, I thought this might be an opportunity to take you along for the ride as I try these out.

Lomandra longifolia ‘Breeze’
The first new plant is
Lomandra longifolia ‘Breeze,’ a dwarf mat rush. I’ve always liked spiky grass– or flax-like plants, and this stopped me with its dramatic long, narrow leaves. It’s listed as maturing to about 30 inches high and wide, though will likely be a tad smaller in a container. The plant is being marketed as a good plant for traffic medians. I’m hoping that will mean that it will require little care–though that may just be a marketing ploy to sell more plants. Another part of the sales pitch is that it should be extremely drought-tolerant once established. Looking around the web I found a listing for it that went on to say that potted versions of the plant will require regular water. Well, it ain’t gonna get lots of water up there on the roof, so we’ll see how well it’ll do. At least its new container is four times the size of the nursery pot and should dry out a lot slower.

Kalanchoe prolifera
New plant number two is
Kalanchoe prolifera, a succulent from Madagascar. It’s definitely an architectural plant that to me it looks a little like an overscaled, cartoon version of a bamboo, with its thick trunks and chunky leaves. The picture here shows the light green freckles on the trunk of the plant, making it a good plant to enjoy up close after you’ve oohed and ahed over its silhouette. Size could be a problem, with some listings saying that it can get to ten feet when it flowers in the winter. But then it dies back and starts all over again. Another experiment for sure.
I picked the final plant, Euphorbia cotinifolia, partly because I wanted something with interesting red foliage. Then when I saw the genus name I was thinking “slam dunk.” Great leafy foliage and extreme drought tolerance because euphorbias as among the camels of the plant world, right? Well, not so fast, because it turns out this is one of the euphorbias that actually likes fairly regularly water. Groan. It was a big plant and I wasn’t looking forward to taking it back to the nursery, let alone having to spend another half day trying to find something I liked only half as much.

Then, researching it some more, I read that it’s actually extremely drought tolerant after all, but that it will drop its leaves in response to drought. Okay, it’s worth a try, I thought. Experiment number three. Placed in the largest of the large containers it’d stand a chance of staying watered enough to hold on to its leaves during the warm part of the year. (It’s naturally deciduous during cold weather.)
So I’ve ended up with three very different looking plants. The lomandra should stay green and grassy year-round. The kalanchoe will shoot up to some impressive height, flower during the winter, and then die back to start all over. And the euphorbia should be a warm, reddish-purple presence much of the year, only to shed its leaves when the kalanchoe is getting ready to show off. It should make for an interesting, ever-changing show.
