Just outside our back door is a beautiful dwarf lemon tree. We don't know what variety we've got, but we love it. The fruits ripen to a beautiful globe shape, and I think they have an almost peppery fragrance. The fruits are ripening, just now. I really enjoyed having an endless supply of lemons when I was sick with laryngitis, a few weeks ago.
Citrus are incredible trees, because they simultaneously have fully ripe fruits fruits and brand-new flowers on their branches. The flowers have an intoxicating scent, that seems significantly more fragrant after the sun goes down.
If even half of the flowers on this tree develop into lemons, we're going to be in Citrus Heaven next year.
