Given the reputation of Takahue catering, the refreshments could well be a real drawcard for some, but the garden will be the star of the weekend.
In 1994 it was a fraction of its current size, but has now grown to the point where Marie's partner Jim Burrough has been known to calculate how many stock units it might have carried had it not been devoted to English and old-fashioned roses, camellias, box hedging and all sorts of other eye-catching species that a layman struggles to name.
"It has a lot of everything really," Marie said.
And it's rather more than a hobby. She spends at least part of every day in the garden, except Wednesdays (which are devoted to art; she is also a very talented painter), adding up to 25 or 30 hours a week.
Incidentally, the dogs are noisily friendly and harmless, but one of the cats reportedly warrants some respect.
