Criniums blooming at Mercer summer 2007

I first heard about these plants at a talk I attended on ‘Recommended Tropical Plants for Houston’. I knew I had to have some even before I laid eyes on them. At the Mercer March Mart I was able to score two of them. Despite a bit of deer damage they are settling in very well and I fully expect blooms next May.

The Crinum lilies are part of the amaryllis family. The leaves reach 3′-4′ in length. The plant will have a 5′ spread after it has had some time to grow. ( I did read a report online of one reaching 8′ across ) Blooms are impressive. You should have several blooms per plant. If in an unprotected location they may need staking but in full sun in a sheltered location they do just fine on their own.

Crinum lilies prefer sun, but will grow happily in dappled shade. Watering needs are average to above average but they are drought tolerant once established. Fertilize regularly to encourage more blooms. Once established you may get as many as 7 bloom cycles a year.

Foliage may brown a bit in the winter here depending on how cold winter is, but they should stay green and leafed out year round. If they lose leaves in the winter they will bounce back come the warm weather.

Divide the bulbs as needed. Plant is poisonous ( what isn’t down here? ).

One of the two crinums I planted grew huge and is thriving but hasn’t yet flowered. The other didn’t put forth a single leaf, but gave me some short lived blooms. Go figure. The deer do not seem to like this plant.

12/13 I saw a beautiful collection of these blooming away down in Galveston last week. There was a row of several of the plants alongside a drainage gully. All were white and all had a half dozen to a dozen flowers in bloom.

I have two of these 6′ apart, one is thriving, the other meh.

These died back during some hard frosts. Much of the plant turned to mush. I cut off the mushy parts and once the weather warmed it started putting out new leaves so it looks to be fine.

Survived and bloomed during the extreme heat and drought of summer 2011

Giant Crinum Lily lining driveway and gardens

In the summer of 2016 I decided it needed to be divided. I ended up with over 200 bulbs. I have it lining both sides of the driveway, along the front bed and partly up the right edge of the front bed. It’s blooming more frequently and seems to resist the hard freezes better.
