Most of the altroemerias we see in gardens and as cut flowers were bred in Europe as are most of those in the current trial at Wisley. But over at Cornell University in New York, a breeding programme is developing some excellent varieties.
‘Mauve Majesty' is the first from the Cornell programme run by Dr Mark Bridgen who introduced a number of good varieties from his previous base at the University of Connecticut, including ‘Sweet Laura'.
His newcomer reaches 60-75cm/2-2.5ft tall, ideal for both the perennial border and for cutting, with a long and prolific season of vivid mauve flowers, shading to cream in the centre, and boldly streaked in crimson. Derived from the familiar favourite Alstroemeria aurea and a large-flowered purple seedling that Dr Bridgen has never introduced, to ensure that the seed germinated the embryo had to be removed in the laboratory and grown on in sterile conditions before being moved into a pot.
One other feature of Dr Bridgen's alstroemerias is that they are unusually hardy -‘Mauve Majesty' will tolerate winter temperatures down to -23C/-10F or even -29C/-20F with a deep mulch. We may never get winters that cold in Britain, but when some alstroemerias are noticeably tender it's comforting to be able to depend on this one.
You can read more about Alstroemeria 'Mauve Majesty' in the Cornell University Chronicle.
Alstroemeria ‘Mauve Majesty' is available from these RHS Plant Finder nurseries.
