They last for about two weeks and gradually fade to a lighter pinkish hue.
For best flowering, however, part shade is best.
Also, in a partially shady location, it tends to bloom earlier than in the full sun.

Types of Red Spider Lily
The plant has different names, each describing a special feature.
The flowers appear before the evergreen leaves unfurl, hence the name naked lily.
The name spider lily comes from the stamens of the flowers that resemble spider legs.
In Florida, the bloom coincides with hurricane season, earning it the name hurricane flower.
Though they do not need any pruning, you may be tempted to clean up their appearance.
Do not prune the flower when its foliage is yellowing.
That is the time when the bulb is receiving nutrients to make its best blooms in the next year.
Instead, wait until the foliage is completely withered and dried up before pruning.
Do this in the summer when the plants are dormant.
The containers must be very large and deep to allow for expansive root growth.
The plants wont bloom if the container is too small.
Space bulbs 6 to 8 inches apart in a container as you would in the ground.
Just be careful not to overwater or it can develop bulb rot.
The one thing this lily attracts is a lot of pollinators.
Bees, butterflies, and birds flock to the red spider lily when it is in bloom.
Try replanting them so the necks of the bulbs just barely protrude up from the ground.
Unusually severe winters can cause these bulbs to temporarily refuse to flower.
However, extreme cold may permanently kill the bulbs.
What Does Red Spider Lily’s Flowers Look and Smell Like?
Red spider lily gives off a soft and slightly sweet fragrance.
Unlike manyhybrid bulbs, red spider lily bulbs do not decline over time, provided they are properly fed.
Deadheading does not prompt another flush of flowers with this plant.
In the regions where it is hardy, the foliage on red spider lilies remains evergreen through the winter.
Allow the leaves to remain in place, as this will help the bulbs restore themselves.
