Alstroemeria exerens
This is a high mountain beautiful Alstroemeria. It is rather low, but has huge flowers, either pink or whitish. Endemic. Excellent ornamental value. Height: 35 cm.  The easiest form to germinate this species is to plant it in autumn and expose the seeds to natural temperature fluctuations. If you decide to do it "scientifically," soak the seeds for a day or so in water, then put them into wet sand and put them into refrigerator at about +2 +5 oC for about 30 days. Allow the seeds to breathe (ventilate from time to time) and check the humidity of the sand (it tends to dry out quickly, so adding moisture every three-four days is a must). Then take them out and plant at room temperatures. If not all seeds or few seeds germinate, repeat the cold step once more. This plant needs good drainage and relatively poor soil. This is a high mountain beautiful Alstroemeria. It is rather low, but has huge flowers, either pink or whitish.
