Survival

I am back in my New England garden for a quick visit after having been away for six months; the garden is in great shape overall but what has been particularly interesting is to see which plants of questionable hardiness have made it through the winter and which have not. A lot of my plantings are  a bit of a gamble in that way. Moreover, since I was going to be away this year, last fall I planted out a few things that I would have otherwise overwintered indoors on the off chance that they might make it. There have been a few real surprises among those plants that made it and those that did not. Complete losses that I had not anticipated included all the fancy florist's chrysanthemums I grew last year as well as all my Parma violets. I knew their hardiness here would be borderline but in our relatively protected garden and with heavy mulching I was not expecting them to be gone entirely. Similarly, Opuntia cacanapa 'Ellisiana' is completely gone, while the native Opuntia humifusa is flourishing and  Opuntia phaecantha, too, is doing very well. Two year-old cuttings of 'Chicago Hardy' fig froze back a bit but are sprouting vigorously. The heirloom dahlia 'Mrs. I. de ver Warner', known for its atypical hardiness, survived its second winter in the ground unscathed, but another modern dahlia hybrid in a much more exposed spot also survived, even though it is much further behind in leafing out. The poppies Argemone platyceras and Glaucium flavum var. aurantiacum also survived quite happily, and so did all my Kniphofia uvaria seedlings. A healthy 'Souvenir de la Malmaison' rose that should be hardy died while a Phygelius that had not even been happy during the summer is resprouting, if weakly. The foliage of my saffron crocuses, now in their third year, should still be green and photosynthesizing, making food reserves for the corms to power good flowering in the fall, but it has already disappeared almost entirely. I suspect a lack of snow cover during the coldest parts of winter and munching by the rabbits that usually stay in the neighbors' grassier yard are to blame. In any case, I will probably have to replant my saffron patch after this year. On the positive side, by far the most surprising survivals were two tuberoses in a raised bed and, completely unexpected, a seedling Canna indica in a clay pot completely exposed on the front steps of the house. Granted, they are small individual sprouts emerging from formerly sizeable root stocks but even so it is impressive.

The lessons to be drawn from this, I guess, are to a) overwinter cuttings of all fancy chrysanthemums inside, b) experiment with tuberoses planted out and heavily mulched for winter, c) try more dahlias besides 'Mrs. I. de ver Warner' as permanently planted perennials with some winter protection. Always learning!

  1. Some interesting hardiness surprises! Is someone tending your garden while you're away? It certainly looks good for the gardener being away for six months!

    1. The downstairs neighbors did some spring clean-up and mulched everything.

    1. They are great garden plants; I am hoping to collect more hardy species in the future.

  3. Anyone who has been away from a garden from a year and can say what you said is a smart gardener. I leave for 5 weeks in the summer and come back and cry a lot.

    1. Winter dormancy and the cool and rainy New England spring helps - I suspect by the end of the summer things will look much sadder, even though in the newer beds I have tried to plant mainly drought-tolerant and self-reliant things. Here in Delhi my little balcony garden definitely suffered during the mere week I was gone and that despite my landlady's gardener fastidiously watering everyday.
