Alstroemeria 'The Third Harmonic'

Peruvian lily

Herbaceous Perennial

“ A good Alstro is hard to find. The dwarf varieties are ever plagued by snails/slugs, Many of the most exquisite varieties (patented) are poor garden performers, lacking vigor or something. Enter this most fave cultivar. First of all its orange and many will confuse it with the more diminutively flowering A. aurantiacus which can become an ineradicable weed. THIS IS NOT THAT. It’s a polite clumper with enough vigor to send up fully 30″ flowering stems repeatedly for up to 6 weeks in summer. Speaking of which the individual flower will last up to two weeks in a vase. Do not cut them (which injures the plant – it bleeds out) rather gently rock the base of the stem back and forth to detach. This will help and not hurt it. Regular summer irrigation in rich, moisture retentive soil. Winter deciduous. To 2′ wide.” — Xera Plants
