Notes About :Alstroemeria
ALSTROEMERIA PERUVIAN LILY. All are outstanding cut flowers and like a well drained, fertile soil. Mulching, especially the first winter, can make them hardy in colder zones than stated. Hint for Alstroe fanatics: Check out Bomerea salsilla, the climbing Alstroemeria. PLEASE read the following important information about growing and shipping Alstroemerias, which is very important to USDA hardiness zones 7 and colder, less so for zone 8 and less still for zone 9. As you may have noticed, Alstroemerias, especially tall ones, are hard to come by. The following will explain some of that.
GUARANTEE/COLD HARDINESS: The USDA hardiness zones indicated are to be used as a guide only to determine which are hardier than others, which is a guess at best. As with any plant, cold hardiness depends on many more factors than just average minimum winter temperatures: Soil type, fertility, microclimate, time of planting, abnormal weather patterns etc. This is truer to Alstroemerias than with most other perennials and thus we cannot guarantee their winter survival in your area, regardless of your zone. If you are not sure if they’ll grow in your area, try just a few for starters or ask/join a local garden club. Alternatively, you can grow them in pots and winter over in a cold but frost free room – the cooler the better.
SHIPPING/TIMING: The best time to plant and ship Alstroemerias is as early in spring as possible. This way the plants have all season to get established and also ship much better instead later in the season when they are up to 3 feet tall. Into the first week of April we can ship them without top growth, in which state they’ll travel better than with top growth and shipping cost may be reduced (explained later). Later in the season Alstroemerias don’t like to be trimmed down and have to be shipped with tops. This is fairly easy for the remainder of April. Later, May thru mid June they get long, tender stems, up to 2 feet and more, and since they are in 4” pots, sometimes may have only 2-3 stems. Mid June thru mid July we don’t recommend shipping them at all, but can do so at your own risk. The second best time to plant and ship is mid July thru August, as they again can be shipped without tops. But keep in mind that this could affect the cold hardness in colder zones.
SHIPPING COSTS: Mid July thru mid April we ship them without top growth and can fit 6 plants into a medium flat rate box. If the shopping cart charges $18.00 and over, we'll reimburse for amounts over $16.00. 9 plants can fit into a large flat rate box, then we'll reimburse shipping if you get charged $23.00 and over for the amount going over $21.00. This, however, only works if you can receive US Mail and choose them as carrier. Mid April thru mid July we don't recommend it as this is the main growth and blooming season for them.
