Before I started gardening, I thought I was fulfilled.
However, my Experiments with Plants directly and indirectly filled voids that I hadn't even recognised, lifting my happiness to a higher level.
This is a blog about a garden near London, England, and how it is changing my approach to life.

Plant Reproduction (21 JAN 2011)
My mother used to be a gardener, not in a prolific or overtly passionate way though. Her garden flourished gradually year by year. In fact, till my late teens, I was under the impression that she approached gardening as an extension of housework. Then one day I pruned her rhododendron bush because it kept getting tangled in the drying laundry. When I saw her almost in tears, too upset to scold, it dawned on me that plants meant more to her than she let on, however she's been suffering from kidney failure for the past few years which has distracted her attention. I try my best to maintain her garden (under her strict supervision) and to keep her interested in it, entertaining myself with a few experiments in there too, but this blog is about my own garden (where I do as I please).
These photos show the cuttings that I have taken from her garden to nurse in my own : pink rhododendron & lace-cap hydrangea, peachy tree peony, white & mauve magnolia, bright orange azalea, green-leaved pieris & culinary bay. Please note the fox protection, it's worked so far (Promise to my Garden no.3 - see previous post). I'm not sure if the cuttings have rooted or just been preserved by the cold, but they are looking healthy after a couple of months. I haven't given them a gentle tug to check for anchorage, as I would have done last year, because I'm going to trust Mother Nature and leave them be (Promise no.? - OK, I'll stop going on about the Promises). By taking a cutting and rooting it you are guaranteed to reproduce an identical plant to the parent. On the other hand, to combine desirable (or undesirable) characteristics of two different plants, sexual reproduction or hybridisation needs to take place, which occurs naturally with the help of insects transferring pollen from one flower to another. Most garden plants were originally hybridised from their wild ancestors, developing them to be bigger, with more attractive flowers and more disease resistant by careful selection of parents with particular genes.
I knew roses have been bred for centuries, hybrid teas probably the most renowned, and found a couple of articles which have been written so comprehensively, that when read together, even a novice gardener could follow the step-by-step instructions to carry out their first trial in rose-breeding :
(1) When a rose is half open, remove it's own pollen sacs to turn it into a "mother".
(2) Collect powdery pollen from a different "father" rose and wipe it onto the sticky central stigma of the "mother".
(3) Wait for the rosehip fruit to develop & ripen, then cut it open and remove the seeds.
(4) In cold climates, store the seeds wrapped in wet tissue, sealed in a plastic bag, inside a fridge.
(5) After a month, check the seeds every week, replacing in the fridge till little roots can be seen.
(6) Plant the rose seedlings in soil.
I planned to try crossing my blood red and pure white roses in the summer, just to find out if they would produce pink or raspberry-rippled babies. I assumed that I could use the same method to breed foxgloves, but wondered if anyone had already dabbled in this specific field of botany. My suspicion that every thought that one could possibly think has already been thought about and posted on the internet was soon confirmed. I found two scientific papers written by the same person Wilfred Ernest Warren in 1917 & 1922. I delved further, and was stupefied with disbelief when I discovered that he was an engineer, who was keen on foxgloves, bred them and took measurements. He hypothesised that the conclusions from these breeding experiments might help us understand inherited diseases.
WILFRED ERNEST WARREN
Wilf Warren died suddenly on 6th May, 1976, shortly before his 80th birthday. By profession he
was an electrical engineer but since childhood he had a great interest in natural history, botany
in particular. His ﬁrst notebook was written up at the age of 7, and in adult life (in addition to
meticulous botanical records) he kept a naturalist’s diary which makes most interesting reading.
