Pea peregrinations

I’m a complete sucker for an annual climber.  This isn’t, like many of my inner horticultural longings, borne out in my actual garden.  But they call to me, nevertheless. One day I swear I’m going to make me a dozen or two of them stick-tripods and grow every last one of them to perfection.

Me, hackin away at sweet peas last Christmas

The only annual climber to be had in flower right now in my frost-plagued climate is the sweet pea.   And given that this frost-plagued climate has moved to a drought-plagued in one apparently effortless step this year, it looks like its flowering is going to be cut short.  I picked something in the region of 500 stems of the purple, scent-drenched ‘Matucana’ for Christmas day last year.  There’ll only be seed pods this year, the way we’re going.

Sweet peas are frost-hardy enough to sow in Autumn, growing very slowly in winter, then bulking up rapidly in spring for late spring/early summer flowers.  But most annual climbers are frost tender, so like being planted in spring for summer and autumn flowering.

I’ve waxed lyrical about Ipomoea ‘Heavenly Blue’ for too many years in too many places, but have no intention of stopping.  There are few plants that make me ache like this one, and I don’t fully understand why.  There’s their fragility – that always makes for a skipped heartbeat.  And there’s that outrageous, rub-your-eyes-in-disbelief blue. Then there’s the long slender white throat, that isn’t all that evident when you look at the flower straight on, but guarantees that any side-lighting makes the flower look like it’s lit from within.  This plant needs heat.  It barely moves for me before December, and will go with the first frosts in April.  But for just a few glorious weeks…

I’ve never yet managed to get a decent show out of its close cousin, once called Mina lobata, now Ipomoea lobata.  I was always skeptical about their close relationship, but now they’re in the same genus there’s no denying it.  It’s another heat lover, and its hard seed seems to me reluctant to germinate.  Invariably, by the time it does so, there’s not enough time left in the season to get any decent size out of it.  In England or North America they’d simply sow it in a glasshouse or indoors, so as to extend the season.  But we Aussie gardeners just don’t.  I just don’t.  It’s stupid, but I just don’t.  I can’t ever get to thinking about germinating tender stuff like this until well into November.  I’ve really got to lift my game.

Possibly the easiest of all annual climbers is the bog-standard running nasturtium.  It’ll run up and over virtually every obstacle in its path.  Most of the named varieties of nasturtium for sale are over-tamed and over-polite, like a sailor-suited Victorian child who’s had all the will beaten out of him.  But you can still get the trailing types – I bought some in Bunnings just the other day.

I wish I could still get seed of the nasturtiums altogether more refined relative, the canary creeper (Tropaeolum peregrinum).  The common name is uncommonly accurate in its description, with yellow flowers made up of two widespread wings, just like an alighting canary.  Even the leaves are smart, like lobed waterlilies. I’ve no pics other than on 35mm slide, so can’t add one of my own.  But you can check one out here.

One day I’ll also conquer the challenge of growing Rhodochiton atrosanguineum from seed.  This is a tender perennial climber that, due to frosts here, I have to grow as an annual.  So far I’ve only ever bought young plants.  Even they’re hard enough to find, and I wouldn’t have a clue where to get the seed. Again, my pics are all on 35mm, but you can see one on p169 of The Gardenist.  For that you’ll have to buy a copy.  A cheaper but altogether less satisfactory option would be to click here.

Finally – an annual climber I don’t know that I’ll ever bother with.  My rejection of this is as inexplicable as my love for Ipomoea ‘Heavenly Blue’, but there’s no arguing with it.  My heart’s made up it’s mind, and won’t even enter a discussion.  The mad thing is that I can discuss the merits of Black-eyed Susan (Thunbergia elata) – fast and easy to grow, orange (always a good thing!) or yellow, interesting contrast with the black eye etc etc – but I just can’t love it.  Maybe I’ll grow it one day and see if any magic emerges.

The crazy thing is, you can’t get near them to sniff them. For a couple of years running I requested a sniffing pot – a vase nearer the barricades, for noses alone. The exhibitor just humoured me with a very little, very restrained smile.  This sweet pea, by the way, was called ‘Promise’.  But the exhibitor wasn’t going to promise anything.

  1. Thank you for your never ending and contagious enthusiasm for Heavenly Blue. I read about it in your book, and promised myself to try and grow it (In West Gippsland). It was extremely difficult to get hold of seeds, and only three out of the packet have germinated. I will keep one in the greenhouse and report back to you later in the year, in case it does perform well. In the meantime, I’m waiting…. They are about 10 cm tall…. Didn’t someone say that half of the magic is always in anticipation? :-)

    • OK, get ‘em in the ground now, and be generous with water and food. There’s still enough time (particularly where you are) to get some love out of ‘em before the cold sets in. If there was ever a summer tailor made for Ipomoea ‘Heavenly Blue’, this (so far) has been it.
      Keep me posted.

      • Thanks for your advice, Michael. All three Heavenly Blues have been flowering quite nicely. The one in the huge self watering pot in the sunniest corner of the greenhouse is trying to lift the roof off, all the flowers are almost clinging to the plastic sheets, but some flying bugs seem to be very keen on eating up the foliage. This must have got too tasty because of too much love and excess food. The other one, in a smaller pot, is perfoming quite well, and absolutely no bugs – and it’s just about 1.5 meters away from the big pot. Strange… The third one, outside, is my favourite. It has a healthy glow to the foliage, and the flowers were delicate and sky blue, and yes, quite amazing, up until this morning! The ones that opened this morning are lilac, not blue!!! A truly surprising plant. I reckon I’ll grow it again. Thanks for the inspiration.
