Alstroemeria ‘Summer Relieve’ has been a real star in our trials. This patch is now 3 years old, and consists of 9 original plants. Flowering typically starts for us in early May, slows during the worst heat of summer, and picks up again as temperatures cool. Hardiness Zone 5b-8b.
I live in zone 6a. Do I plant this in the fall, like a bulb, or in the spring, like a perennial? Thanks for your help. Maryann
Plant it as soon as you have time.
I live north of Raleigh. Does all varieties of alstroemeria spread like that?
This is a mass of 9 original plants, each of which forms a 3′ wide clump. There are two species of Alstroemeria which spread, A. aurea and A. psittacina. Almost all commercial cultivars are clumpers.
