Part of the Little Girl Series of hybrid magnolias developed in the 1900s, the Magnolia 'Jane' is a cross between M. liliiflora ''Reflorescens' and M. stellata 'Waterlily.' Along with 'Ann,' 'Betty,' 'Judy,' 'Pinkie,' 'Randy,' 'Ricki,' and 'Susan,' the other seven hybrids, Magnolia 'Jane' was created by botanists Francis DeVos and William Kosar at the National Arboretum in Washington, D.C. Some call the plant a magnolia tree, while others call it a shrub, but it's best described as a large, multi-branched shrub.
The flowers Jane magnolia are fairly large, especially relative to the overall size of the plant. Under ideal conditions, the blooms can reach 8 inches across when fully open. The flower color is displayed in two different time periods. When the flower is still closed, the color is burgundy-purple, and the flowers are shaped like tulips. After the flower has been fully open for a while, the color of the outer side of the petals fades to pink. The petals are white on the inside.

How to Grow Magnolia 'Jane'
Plant the Magnolia 'Jane' in the spring or early fall in a location where it can grow to its full maturity without movement, as the shrub doesn't do well with transplanting. Pick a location that allows the roots to spread and branch freely, away from building foundations, walls, and decks
To plant Magnolia 'Jane,' dig a hole as deep as the root ball and three times as wide. Mix the removed soil with compost or peat moss to enrich the soil and loosen existing dirt. After putting the plant in the soil, water it well and then add a 2-inch layer of much.
Plant the Magnolia 'Jane' in a location that has full sun or part shade. Avoid placing it in an area with warm southern exposure, which could encourage the buds opening too early in the spring months. If a magnolia gets too much hot sun, the blooms could suffer from sunscald.
Magnolia 'Jane' grows best in organically rich, medium-moisture soil that's neutral to slightly acidic. Add a layer of root-zone mulch to help the soil retain its moisture, but keep it 4 inches away from the trunk of the plant. Magnolias adapt fairly easily to a variety of soils, including clay, loam, or sand, but it doesn't do well in wet or poorly drained soils.
Temperature and Humidity
This shrub can tolerate temperatures as low as -30 or -20 degrees Fahrenheit. It also needs proper air circulation to avoid powdery mildew, its biggest threat.
Once the Magnolia 'Jane' is established, fertilize it in the spring every two to three years. To fertilize, you can spread compost around your bush in spring and water it in. Then, in early fall, use a fertilizer geared to acid-loving plants, such as Holly Tone.
This deciduous shrub needs to be watered weekly for the first growing season. When it's hot, water every few days in an effort to soak the ground up to 8 inches. Check the first 2 to 4 inches of soil to see if it's dry; if it is, it's time to water. If the magnolia is well-established, it's moderately tolerant to drought.
Propagating Magnolia 'Jane'
Magnolia 'Jane' is a sterile plant, meaning it doesn't produce seeds and must be propagated via cuttings.
- Choose stems that are between softwood and semi-hardwood growth, and take them in the morning when the plant is holding more moisture.
- Snip 4 to 6 inches off the chosen stem with sharp pruning shears, and wrap it in a wet paper towel.
- Dip the bottom of the cutting into rooting hormone that contains IBA with a 4,000 to 5,000 parts per million solution.
- Plant it immediately in a 5-inch pot filled with moist potting soil, using a misting chamber if you have one available. The cuttings will form rooms within eight weeks.
Pruning Magnolia 'Jane'
The Magnolia 'Jane' doesn't need much pruning during the first couple of year. As a general rule of thumb, the earliest-flowering trees and shrubs set flower buds the previous year, so be careful not to prune at the wrong time and end up losing flowers. Simply remove the dead or damaged branches immediately after the plant flowers during the Spring months.
However, there is no rule stating that you have to prune Jane magnolias at all, although it is advisable to prune away any suckers that might develop to keep the shrubs looking neat. After two years, don't prune the magnolia tree at all because the tree won't heal from the cutting.
