Pondering geranium leaves

9 comments


By John Beaulieu (Bowl-you)

It has been a very busy summer, and I’m only now finishing off the planting of my many geranium seedlings which were winter-sown in pots (in January 2013). Most seedlings are now a good size, and it is interesting to see all the different leaf shapes and sizes. As I study these plants and hurry to get this work done before the tree leaves start changing colour (any time now), I can’t help but ponder about geranium leaves.

Although there is a certain sameness to geranium leaves, they are at the same time quite varied in shape.

At one time (not that many years ago) I had a hard time to tell true geranium leaves from the many look-a-like weed leaves that would appear in the garden.

A few years back when I was enjoying the hunt for new varieties (hard to find around here) at some favourite garden centres, I came across a pink plant that had very geranium-like leaves. The flowers seemed much like a geranium, although the way they were held on the stalk was odd. The staff at Lost Horizons soon set me straight, it was not a geranium, but rather a sidalcea, a mallow-like plant that I was not familiar with. Oh well, I had a moment of excitement thinking I found a new geranium.

Geranium leaves come in all sizes, from the tiny, less than half inch leaves of Geranium sessiliflorum subspecies novaezelandiae ‘Nigricans’ (small plant – big name) to G. phaeum that can have leaves almost a foot across!

This is a G. phaeum seedling that has sprouted in the lawn. One leaf is almost half variegated. Although interesting, I come across this several times and it is usually caused by some stress on the plant and is temporary. Future leaves are usually normal.

Also with the phaeums, often those with the darker leaf markings will show a white leaf with red markings. Again, this is just a random stress thing and will not show on other leaves as the plant grows. It is really the lack of green, showing that the dark markings are red, although they show as a dark green or brown when the base green colour is there.

On some occasions the random variegation seems to be more virus induced and that may appear on other leaves of the same plant. It may or may not show up on the next years growth. Sometimes it is quite interesting and we can always keep our fingers crossed.

All this leaf pondering is not getting my seedlings planted! I hope the rain holds off, so I can get the planting finished today. The weather is being very fickle again… Two nights ago we were down to a record 3 degrees C with a frost warning (it did not frost) and today we are heading to record 33 degree C temperatures with the humidity making it feel like the high 30s.

When I Read Your Blog On Geraniums . It Was very informative. They were one Of My Mums Favourite Plants. I Will Try to get some for my Garden I've Had Them Before. But not for a long time.

Very informative John, you know your geraniums don't you. I do grow a few and I'm just beginning to notice the difference between the leaves.

Very interesting blog. I grow a few different geraniums, they are useful plants, I especially like the ground cover ones with the scented leaves.

Very interesting. Some are quite distinctive but I really struggle to find differences in others. Sidalcea is a name I can never remember. Diane Bulley once sent me a white one which she said would prevent butterflies laying eggs on cabbages. So I tried it. The butterflies flew round the cabbages as usual but not one laid eggs there!!!

I found what I thought may be a geranium...but seeing your blog, I'm now wondering if it might be a very compact buttercup. Rats, I really thought I had another geranium. Well anyway I'm going to leave it where it is and see if it makes it thro the winter. If I post a pic of it will you give me your opinion? Thanks for a very informative blog.

Lori, those buttercups are the worst! A few years back, I came across some sprouting plants that looked like geraniums. We were near a small town about an hour away from home (I was giving a slide presentation on butterflies to a local hiking club), and I did not have time to collect any plants. The following week, we drove back to the spot along a stream and I had what I needed to collect a couple plants from the bank. The transplants did well and eventually flowered... They were the nicest buttercups! I had been hoping they were a native geranium such as G. maculatum. The only geranium I have found in the wild is G. bicknelii, and of course G. robertianum (Herb Robert) which must grow world-wide by now! Both are equally weedy. But, I do give them some space in my wild areas (with the buttercups).

Bowl You fancy confessing in public to digging up wild plants - if you were in Britain we'd have the law on you! If you want any more buttercups please do let me know - ours are the creeping kind and there are plenty to spare, lol.

It was not exactly in the wild.... This was an area in town where the plants in question would be considered weeds and were mowed and sprayed. We do have a big problem in some areas of Ontario, such as up the Bruce Peninsula where there are lots of rare fern and orchid varieties growing along the limestone cliffs of the Niagara Escarpment. Poaching of these plants is a real problem! Sadly most of these plants have very specific requirements and I suspect that most people lose what plants they take.

In that case I let you off!! You are lucky to live in a place where there are such desirable wild flowers. Most of Britain's wild daffodils have disappeared into peoples gardens over the years and as you say it can be a real problem.
