Hanging Colander Lettuce Pot

Photo by Gayla Trail  All Rights Reserved

You are looking at one of this year’s serendipitous brainstorms. I feel perhaps a little bit too genius for coming up with it, when really, it’s just an enamel colander filled with ‘Sea of Red’ cutting lettuce and hanging in a wire basket. I quite like it. So much so that I haven’t had the heart to harvest it! Yet.

Here’s how this happy marriage came about. I had this heavy wire hanging basket sitting around, going unused. It’s the sort that is typically lined with coir, which is fine in most gardens but hard to keep hydrated on a hot and sunny roof. While, I’ve found it difficult to use as-is, I’ve kept the basket waiting for a new use to present itself. Despite the issue with hydration, stylishly understated and black hanging baskets made of a sturdy materials are hard to come by so I wasn’t about to get rid of it.

I bought the colander at a local secondhand store with the expressed purpose of growing greens in it. I liked the pairing of butter cream with bright red trim. The holes are small enough to hold soil without adding an extra liner, and the drainage they provide is perfect for growing small greens or herbs.

Once I had planted up the colander, I thought it might be better served sitting up off the ground. Low and behold it fit perfectly inside the otherwise useless wire basket. As an added bonus our digging mammal visitors (squirrels, raccoons, etc) have not been able to get at it, while a second pot of ‘Sea of Red’ cutting lettuce has been dug up several times over the season.

Incidentally, I have experimented with this particular variety by growing the heads spaced at a distance from one another and tightly clustered as you see it here. I prefer it grown together and like the way the spear-like leaves create a literal sea of rich, mahogany that lights up when the sun hits it just so. It’s as satisfying to look at as any flower basket I have grown and I might even eat it for lunch sometime soon before the plants bolt.

Red Potentilla

Over the weekend I visited a beautiful backyard garden in Aurora, Ontario called Merlin’s Hallow where I saw this striking red potentilla. Since then, I’ve been unable to put it out of my mind. Unfortunately, I don’t know its name.

If you think you know, please do share in the comments section below.

Update: I think we’ve got an identification: Potentilla atrosanguinea ‘Gibson’s Scarlet’¢. Thanks Kim and Pam!

Corsican Mint (Mentha requienii)

Project “Let’s Not Kill the Corsican Mint” is well underway and so far so good. You see, I tried to grow one in my community garden plot last year and failed. If I can manage to move from not-killing the plant to encouraging it to grow lush an over the sides of it’s pot I will be very happy indeed.

Looking back I have a few theories around that failure that I am testing on plant number two, the sequel. I was naive and a bit lazy with plant #1. I just shoved it into the part of my garden where the other mints grow and called it a day.

Done and done. Literally.

But Corsican mint (Mentha requienii) is not the same as tough as-nails mint. It is very diminutive, spreading plant — more like a moss than a mint. It has delicate roots, while regular mint can bust through all sort of barricades.

  1. Good Drainage: Corsican mint is the sort of creeping plant that grows well between paving stones. It is sometimes used as a ground cover and can take a bit of foot traffic. This leaves me with the impression that it requires very good drainage. Regular mints like good drainage too, but they are less picky. I have worked hard on the soil at my community garden and it is good. However, I lost a thyme (also requires good drainage) in that exact spot so I think the drainage may not be as good as other parts of the plot where thyme has survived. Although, wild strawberries live there now and they have overwintered and happily spread themselves about. Go figure.

    My strategy with Corsican mint #2 is to grow it in a pot in which I have added a bit of sand and grit for extra drainage.

  2. Dappled Light: Mistake number 2 was planting the Lilliputian Corsican mint (they don’t grow more than an inch tall) nearby much taller mints. Over the course of the summer, the monster mints grew and took over the space as mints are want to do. Corsican mint likes dappled light, but I do not believe it likes to be shaded out completely. I am currently keeping plant #2 on this shelf, which resides in the partial shade portion of my roof. So far it looks happy and is growing. Life on the roof is hot but it is protected in that spot and I can check on the plant daily. I only visit the community garden plot weekly or twice weekly. The most fruitful observations are made when you can check on a plant every single day.
  3. Soil Moisture: This was the one thing I did right, but without the proper drainage. Corsican mint likes to be kept moist, but not too moist. It should never dry out. In a word, it is finicky. It likes things just so. The trick is to figure out what that means exactly and keep doing it.

Black Swallowtail Caterpillar Osmeterium

I’m still a little bit obsessed with the Black Swallowtail Butterfly caterpillars, so please forgive the focus on a singular topic.

Pictured above is the second, larger caterpillar displaying his/her osmeterium, a self-protective scent gland that is released when the caterpillar feels threatened. This one released its osmeterium when Davin picked up the container the dill is growing in to get a closer look. Apparently they omit a foul smell the ward off predators but I haven’t noticed anything yet.

I look forward to locating them every morning when I go out to check the plants. So far they are always on the same stems but I suspect they will move soon since you can see this one is overeating the stem it is currently attached to. It’s growing larger with every passing day, too. Right now neither are eating enough to decimate a plant but we’ll see what happens as they grow.

Last year we had the mantids, this year its swallowtail butterfly caterpillars.
