Alstroemeria 'Casablanca' is one of the most amazing alstroemerias we've grown. Although it was hybridized for the cut flower trade, Alstroemeria 'Casablanca' has proven to be amazingly winter hardy, enduring -8 degrees F in Michigan with no problem. The 3' wide clump produces 40" tall stalks topped, starting in early June, with clusters of large white flowers flushed with pink on the back and flecked with maroon markings on the flower face...a hummingbird party plant. Alstroemeria 'Casablanca' flowers continuously for us all summer...simply outstanding. Bogart not included.
(US PP 9,393 expired) We are pleased to share this wonderful introduction from the breeding program of Mark Bridgen of Cornell University. Alstroemeria 'Freedom' boasts similar heat- and cold-tolerance to that of Alstroemeria 'Sweet Laura'. The winter rosettes of green foliage give rise from June through September to 30" tall spikes of peachy-red flowers (RHS 53D), highlighted at the tip of the uppermost two petals with a bold white pattern speckled with carmine...a hummingbird delight. Alstroemeria 'Freedom' has proven to be much more of a clumper in contrast to the more common runner, Alstroemeria psittacina.
(aka: Alstroemeria 'Inca Ice') Alstroemeria 'Koice', from Holland's Könst Alstroemeria, has been a star in our trials as well as at Walters Gardens in Michigan. For us, the clumping Alstroemeria 'Koice' begins flowering in early June and continues nonstop until frost. The 18" tall stalks of Inca Ice princess lily are topped with clusters of light peach flowers highlighted with cinnamon flecks...a hummingbird treat. In 2011, Alstroemeria 'Koice' sailed through -12 degrees F in western Michigan!
This 2007 introduction from Cornell's Mark Bridgen makes a compact clumper topped from mid-June through September with abundant clusters of 30" tall, sturdy, upright spikes that end in rosy-pink flowers, two petals of which are highlighted with a yellow base. Because Alstroemeria 'Mauve Majesty' makes a tight clump, it is perfect for a small space in a small garden. Alstroemeria 'Mauve Majesty' has been a great performer in our trials and a hummingbird hangout.
(aka: Alstroemeria 'Zaprifabi') Alstroemeria 'Princess Fabiana' from Holland's Van Zanten Plants is one of the standouts in our heat-tolerant alstroemeria trials. Alstroemeria 'Princess Fabiana' is a lovely white-bordered sport of Alstroemeria 'Princess Paola' (aka Stapripal). The 10" tall dwarf clumps, which were actually bred for the container plant market, are topped with creamy white flowers with burgundy markings starting in early summer. When summer temperatures rise, flowering slows until the weather cools. As is so often the case, the plants were given nonsensical names, so we used their illegal trade names as the cultivar names.
(aka: Alstroemeria 'Zaprimat') Alstroemeria 'Princess Mathilde' is another of the rock garden alstroemeria hybrids that stood out in our trials. Alstroemeria 'Princess Mathilde', discovered as a sport of Alstroemeria 'Princess Zavina', forms a 10" tall x 18" wide patch topped in summer with large peachy-orange flowers flecked with burgundy...quite showy. While the princess series Alstroemeria selections we offer are good in hot climates, they are that much better in areas with cool summers. If they aren't hardy in your zone, alstroemerias make fantastic summer container plants for the patio.
(aka: Alstroemeria 'Staprioxa') Alstroemeria 'Princess Oxana' is another of the rock garden alstroemeria hybrids that stood out in our trials for both heat and cold tolerance. This 2002 introduction from Holland's Van Zanten Plants forms a compact clump 10" tall x 18" wide topped, starting in midsummer, with large rosy-red flowers, highlighted by a central yellow band with brown bands in the background. For us, flowering slows during the hottest part of summer, but resumes when the weather cools...great in the rock garden or in colorful summer containers.
Alstroemeria psittacina 'Variegata' is a Japanese selection, that improves on the native Brazilian species, Alstroemeria psittacina, with dramatic, white-edged leaves. This winter-grower makes a spreading mass of attractive foliage to 15" tall x 3' wide in 6 years (much slower than the species). In June, the flowering stems erupt to nearly 3', each topped with narrow tubular flowers speckled maroon and green...a hummingbird magnet. After flowering, Alstroemeria psittacina 'Variegata' goes semi-dormant for the summer, re-emerging in September.
From Mark Bridgen at Cornell University comes this extraordinarily hardy and fragrant princess lily. The winter rosettes of green foliage give rise from June through September to 30" tall stems of golden flowers, highlighted with orange tips and cinnamon specks. The sweet fragrance of the abundant floral display makes this a must for the summer border...and is a hummingbird magnet. In our climate, many princess lilies die of heat stroke when they experience our summers, but not Alstroemeria 'Sweet Laura'. Once established, this Alstroemeria caryophyllaea hybrid spreads very slowly, unlike many of the more aggressive species.
Alstroemeria 'The Third Harmonic' is an amazing hybrid from California breeder George Hare that is little known outside of the West Coast. After several years in our trials, it has ranked as one of our top performers. This sterile cross of Alstroemeria 'Peach Harmony' and Alstroemeria aurantiaca is a vigorous grower topped virtually all summer with 4' tall flower stalks with clusters of large, medium orange flowers, each with a purple-flecked lip...a hummingbird favorite. The back of the petals also have a lovely contrasting burnt-maroon flush. Whether you enjoy it in the garden or indoors as a cut flower, this is a real winner!
