Gloriosa rothschildiana care
Would you like to amaze your friends with these amazing flowers? These tips will help you in growing gloriosa lily.
Sunlight and moisture needs for gloriosa lily
Gloriosa loves full sun but will grow in partial sunlight. 6-8 hours of sunlight a day is ideal.
For those who live in hot southern climates, plant the tubers so that the flowers will get full sun, but the roots will remain shaded. Low growing shrubs around the plant will accomplish this.
Some protection from afternoon sunlight is helpful.
Prepare your soil by adding compost or other organic matter, such as peat moss or manure. This not only adds nutrients to the soil, it also helps it to drain well.
Half strength fertilizer applied every two weeks during the growing season will keep your gloriosa lily blooming vigorously all summer long, and even into fall.
Gloriosa rothschildiana prefers well draining soil that is kept moist, especially until the shoots appear in a few weeks.
Reduce the water to a couple of times a week or when the soil feels dry just below the surface. This plant requires about 1 inch of water a week, so extra water may be needed during hot, dry spells.
Gloriosa likes high humidity and is not happy in arid climates.
Planting tips for gloriosa lily
Plant the tubers in the spring once the soil has warmed and there is no danger of frost. Install your trellis and plant the tubers about 4 inches away from it.
Tubers are laid on their sides in the planting holes about 1 foot apart. Cover them with soil and firm down the soil well so that you don’t have any air pockets.
Glory lily prefers soil that is neutral to slightly acidic with a soil pH of 5.8 – 6.5.
A light well draining soil made for African Violets works well or make your own with a mix of 3 parts peat moss, 1 part sand and 1 part perlite.
The tubers will sprout in 2-3 weeks. Keep them moist until this happens.
Mature size of flame lily
This stunning plant will grow to 60-72 inches tall. Glory lily does best when given a trellis or arbor to climb on.
Gloriosa does not produce tendrils in the normal way that vining plants do. Instead, the way that the leaves are shaped allows them to cling to a trellis or even another tall plant, like a sunflower. This pulls the vines upward for the dramatic show of flowers.
The tubers of gloriosa lily spread vigorously. It is classified as invasive in Australia, as well as several Pacific islands. No US state classifies it this way, but because of its potential to be invasive, it is recommended that you grow gloriosa lily in containers if you live in an area where it will over winter.
If you would like a wall of brilliant color that lasts all summer, gloriosa lily is the plant for you!
Gloriosa lily blooms in mid to late summer. The plant is fairy tidy, so deadheading it does not require too much pruning.
Deadheading the spent blooms on this lily will promote more flowers. Check out this post for tips on deadheading. For those of you who hate this task, check out this post for plants that don’t need deadheading.
The showy flowers appear on flower stalks up to 7 1/2 inches long. Each flower has 6 widely spaced petals that bend backwards and 6 outward spreading stamens that can be up to 1 1/2 inches long.
Flowers come in brilliant combinations of dark red, bright pink, orange, yellow, and striped pink.
The leaves occur in alternate spacing but some may be opposite, too. The have a lance like shape and are tipped with tendrils. Leaves are about 5-8 inches long
The leaves of gloriosa lily appear in the spring. After flowering, the stems die back.
Propagating gloriosa lily
Flame lily grows from tubers which go dormant during the winter. To get more plants, divide the tubers about once every three years.
Gloriosa lily can also be grown from seeds.
Common pests and diseases
Gloriosa lily may sometimes be infected with cucumber mosaic virus, root rot and can be attractive to aphids.
If you notice the leaves of your plant turning dry and pale colored, this is likely because of too much sun, rather than a disease. Try moving the plant so that it will get some afternoon shade.
Curling leaves might indicate that red spider mites have taken a liking to the plant. Spraying the entire vine when you water will help keep them away.
Is gloriosa lily a perennial?
Gloriosa lily is grown as a perennial in mild climates – USDA hardiness zones of 9-11. ( It might over winter in Zone 8 with mulching.) In colder areas, USDA 3-7, it is grown as a summer bulb because of the dramatic flowers.
You can enjoy the flowers all summer long, and then either let it die underground, or lift and store the tubers and plant them again in the spring.
Place the tubers in lightly damp peat moss and allow them to rest for a few months before replanting.
