If you are referring to my Greek Βασιλικό Μαύρο (Vasiliko Mavro, rough translation = Royal Black), unfortunately I removed all the growing shoots last year to stop it growing any higher, and I didn't pot them. I was a bit too busy at the time, but now I regret not doing so. It was a mistake, coz now I only have the one tree of that variety, and there are no new shoots - yet.
If you are referring to my Italian Purple or 'Brown Turkey' (allegedly), cuttings are plentiful, and I don't charge for them. I'm not a commercial outfit, and I even pay p&p myself. My only concern is whether they'll 'take' this time of year, coz they're in full swing, so to speak. Most of the foliage has also suffered frost damage - I didn't take some basic precautions prior to the recent frosts, and I've a feeling that will adversely affect this year's crop.
But if your eye is on the VM, then you might hafta wait till next year (or maybe even longer) before you'll get any cuttings from it.
Where are you based when you're not in London?
