Alstroemeria Indian Summer ['Tesronto'] (Indian Summer Peruvian Lily) - This perennial forms large dense clumps of dark bronze green foliage. In early summer through late fall (and through winter in frost free gardens), at the top of the stems that have risen 2 to 3 feet high, are umbels of beautiful coppery-orange and golden-yellow flowers with dark burgundy streaks. Like other Alstroemeria growth emerges from a crown of slender rhizomes that attach to succulent storage roots below and each year new unbranched shoots arise from the crown to produce the leaves along the stem with the flower arise at the top of these stems. Plant in full sun to light shade and water regularly to occasionally in late spring and early summer. Tolerates fairly dry conditions in coastal gardens but vigor and flowering is best when plants are irrigated at least occasionally. This variety was bred for cold hardiness and should tolerate temperatures as low as 5°F, particularly if mulched. When trimming or cutting Alstroemeria for flowers it is best to pull the stems out so they break off below ground at the crown to stimulate the formation of new shoots, but do so carefully so not to pull out pieces of the rhizome itself. This plant has been incredibly long blooming for us in Santa Barbare with flowers seemingly on the plant year-round and with its rich bronze leaves (when grown in at least half day sun) and bright cheery flowers, this plant will decorate any garden, and luckily they are pretty much ignored by deer. It would work great as a border plant, specimen planting or in the cutting garden and spectacular when planted in a mass planting. We find the name Indian Summer quite fitting for this plant as we first saw this beautiful plant when touring Wisley and Kew gardens in England in the fall (what is sometimes called "Indian Summer") of 2017 and thought it so sensational that we had to track it down. In our own garden this plant can be found blooming through New Years Day and with lingering flowers continuing through to summer, going later and starting earlier than any other Peruvian Lily we have ever grown. Alstroemeria Indian Summer was first displayed at the 2013 European Spring Pack Trials by HilverdaKooij Plant Technology of the Netherlands. It was noted to be part of a series of Alstroemeria that were bred for European gardens with claims that they are cold hardy to -15°C (5°F). 'Tesronto' had Plant Breeder's Rights asserted in Europe but was never patented in the US, though a sport from it that was called 'Tesronto Imp' was later patented. The genus Alstroemeria was named by Carl Linnaeus, often called the Father of Taxonomy, for his friend and student Klaus von Alstroemer (Clas Alströmer), a Swedish baron. Alstroemeria plants come from two areas within South America with summer growing species restricted to eastern Brazil and winter-growing plants from central Chile with common names such as Peruvian Lily, Parrot Lily, or Lily of the Incas. Images of this plant taken at the Royal Botanic Gardens at Kew on October 3, 2017.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have visited. We have also incorporated comments received from others and always appreciate getting feedback of any kind from those who have some additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that would aid others in growing  Alstroemeria Indian Summer 'Tesronto'.
