Hardiness of 'tender' plants
My Feijoa sellowiana, Punica granata (not surprisingly), Callistemon rigidus all shrugged off nights of -8 Celcius and having their pots frozen. Agapanthus africanus suffered, but lived. Hedychium gardnerii, Acacia retinoides and Caesalpina gillespii all survived being left (very) dry and dropping below zero. I am surprised about the first. Brugmansia aborea lived, but hasn't show signs of life yet, and Erythrina crista-galli seems to regard our apology for a spring/summer as not worth sprouting for. How ON EARTH does it grow in Edinburgh? And I have lost half my rosemarys, most of my marjoram, but not my origano, and some of my thyme and winter savory. Plus, I moved most of my horseradish and have lost the lot! Perhaps it is sensitive to walnut exudations. Regards, Nick Maclaren. |

Yes, the pomegranate came though - it's real problem is waterlogging, as it grows in some really harsh climates. Other people may be interested to know that both it and Feijoa seem to be hardy in pots even here; they make good patio plants. | I've forgotten where you live so not | sure if your Erythrina will ever show it's bright red flowers and Cambridge. But it is no colder than Edinburgh. | finally because of the 'walnut exudations' which I don't think had a | connection with the horseradish, and you didn't mentioned anything | about squirrel, I don't think that squirrels eat horseradish :-) | I'm now humming Bob Marley's 'Exodus' song .... How do | you do that?! Dunno. I recognise the name, but only vaguely. Regards, Nick Maclaren. |

I have a recollection of seeing it in a sun-trap corner in either the University or the Botanic Garden, but I may be suffering from senility and be remembering it somewhere else (Oxford?) | Edinburgh often feels a lot colder in winter than it actually is, | due to windchill..if you're out in the unprotected blast of east wind | howling down the street straight from Siberia. But the proximity of sea | means that in wind-sheltered spots, such as the courts sheltered by | granite tenements on all sides, the temp may seldom fall much below 0C; | much warmer than places 20 miles inland. Or Cambridge :-) The problem with E. crista-galli is that it doesn't appear to sprout from its roots until the soil warms up - and the past few years have been damn cold (in summer).

There is I am convinced no reason to it all, I had been told my two tender Fuchsias would be ok outside (paniculata and boliviana) and so it was, they came up at the same time as the hardy sorts. my Tibouchina's though seemed very dead both grandifolia and urvilleana but yesterday I spotted that they were shooting at the base, will they get back to flowering size in time? no idea leaving them out was an experiment. As for the Erythrina last time I tried it did make it as far as winter, this time I have sown the seed in ericaceous compost and its looking a bit happier! -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collection of Clematis viticella (cvs) |
