This small tree took EFFORT here in Central Texas ! I purchased it as a one gallon sapling , Babied and coddled it through four broiling summers . When I say baby I mean baby , Every afternoon irrigating it around the base and hosing down the foliage . purchasing premium fertilizer from the san antonio botanical garden , and mulching it heavily in summer to keep adequate moisture . Finally after four years it is now over 10 feet tall (I think it is done growing) and I have the ONLY susan magnolia in town it survived this 2011 Texas drought with minimal leaf burn and still flushed new leaves every couple weeks . I have to say this tree is WORTH the effort to grow here in Central Texas ! You will have to give it the TLC of a young child but in spring it is the most beautiful front yard tree... read more

I believe" quinquepeta" and "liliflora" is the same animal, but I could be wrong.

I bought this plant after feeling very sorry for it in a nursery; it was a dry, blasted stick with a sale sticker, and planted it out with no expectations of it even surviving.
The first year it stayed a stick and sulked, the second it doubled in height to about 2 m and exploded in a profusion of lovely upright stellata-style blooms.

Requires little to no care here, getting half day shade amongst other, taller evergreen + deciduous trees.

The only drawback I would ascribe to it is the fact that it, like the other smaller stellatas, looks bedraggled and not very exciting with its spindly little branches etc for half the year, and is not as architectural as the other magnolia species in winter. But ... read more

Bought as a plug plant circa 1999 from Mair and Thompson, UK. Quick to grow, it was placed in present position in 2001, and has largish dark green, slightly wavy leaves, which clothe the plant well. Quite compact, flowers well from an early age. On forming a full bud before opening the flowers are a deep purple, opening to a bright cerise purple. Easy, needs no pruning. zone 8a UK
