Magnolia acuminata 'BLUE BABY' cucumber tree, magnolia

Blue Baby is an attractive miniature of the sensational Blue Opall magnolia with bluish buds. If you stand both magnolias next to each other, you will probably not find a single significant difference in the color, shape of the flower or the leaf, but everything is about a third smaller – the size of the flower, of the leaf, and the plant itself. The flowers develop from pointed buds that have a striking, steel-blue frosting. Once opened, they reveal pale banana yellow color of the inner petals, which almost never fully open and usually remain upright like tulips. It has a faint fragrance. A great advantage over many early varieties is their late flowering season (second half of May), mostly at the same time as the leaves emerge, so they avoid dangerous late frosts. The flower buds are not as obvious as on earlier species and the flower often surprises you on a branch where you would never expect a flower to form.

Deciduous leaves are broadly ovate, large and have a bright green color that remains fresh until the end of summer. It grows upright, medium fast to a narrow conical to columnar shape. Being too young, the mature height of this variety has not yet been determined, but it is estimated at 4-5 m. It mostly does not suffer from diseases or pests and can handle even temporary waterlogging.

Magnolias are not supposed to be pruned. You can prune old shrubs if they are ill, or trim them to shape or to reduce size, or make an elementary cut to young plants of unsightly or unhealthy appearance. Do this as soon as possible after flowering to secure setting of flower buds for the following year. Be aware that each magnolia can respond to pruning differently.

Deciduous magnolias are quite easy plants. All they need is light, well-drained, acidic soil with equal moisture throughout the year. Once established they can do with occasional drought as well as excess water but will not look as nice as the ones with regular watering. Just pay attention to how to plant your magnolia. First, find it a spot where it will live forever and ever. It does not like transplanting. And as it makes shallow roots reaching well over its spread, stay away from disturbing the roots by digging or messing about around it. Just cover the soil with bark mulch and do not plant anything else near it after say the second year after planting onwards. You could damage the very important top roots that absorb maximum moisture and nutrients from the soil. Also avoid planting magnolia too deep. This way you could be digging its grave. Cucumber magnolia is very hardy, some sources even claim it can survive -40 °C (USDA zone 3) which we weren’t able to prove. Keep it always mulched as a prevention from drying out.
