Goodday Shaun,
Unfortunately they all died on me.
I love Gumtrees, the smell, etc. They remind me of my many travels (even immigrated for a year once) to Australia and New Zealand.
I did found some gumtrees in California but it was not the same - the view of the countryside and the smell in Aussie was much more peculiar. You live in a great country which always has a special place in my wife's and my heart.
If you have a chance, you could do me a favor to send me some seeds... I wouldn't know how I could reimburse you for mail but if you are willing then please send me a personal email for my addres. If it's difficult no problem too.
Kind regards,
Eric
