The flowers of the alstroemeria plant are so interesting and diverse that they are often likened to that of orchid blooms.

Alstroemeria Care Must-Knows
Alstroemeria is a fairly easy plant to grow. The roots of the alstroemeria form tubers, which are a form of storage root. These tubers allow the plants to store up nutrients and water for times of need. This allows the plants to deal with drought and other stressful periods better than most.
Tuberous roots also mean that these plants are easy to divide and multiply. As the plants form large colonies, it's easy enough to dig them up and divide them. Make sure there are healthy tubers among the bunch, then simply replant and water well. In general, alstroemeria doesn't enjoy having their roots disturbed too often, so avoid dividing every year. With some of the more temperamental varieties and species, you may have to go a year or two after dividing with no blooms as the plants reestablish.
Like caring for any perennial, plant alstroemeria in well-drained soil that won't stay too wet. Because of their fleshy tuberous roots, alstroemeria is likely to rot in too much water. However, they do appreciate consistent moisture, especially during flowering, but once the plants are established, they can handle short droughts without a problem.
For the best display of flowers, make sure to grow these plants in full sun. Many varieties can handle part sun, but they are much more likely to flop and not be as floriferous. To prevent flopping, which is especially likely with older varieties and varieties grown for cut flowers, make sure to have some sort of support or stake to hold up the tall stalks.
Cut Flower Care
Growing alstroemeria in your home garden is a great way to supply cut flowers with minimal care. It's actually best to not cut alstroemeria blooms from the stem as you would any other cut flower. The best way to pick stems of blooms is to pull the stem out of the flower. Simply grasp the flower stalk at the base of the stem near the ground and pull upward until the whole stem comes up from the ground. This helps encourage the plant to form new shoots at the base. Cutting the stem halfway down (like you might any other bloom) can actually slow the growth of the plant. Once you pull the whole stem up, cut the stalk to the length you need, remove any lower foliage that might be sitting directly in the water, and place in your vase. You'll have blooms for weeks!
