The Albizia julibrissin - Persian Sleeping Tree

FAQ / Frequently Asked Questions

Is the Albizia hardy?

The Albizia julibrissin is hardy, but it does lose its leaves in the winter. Then it becomes a bare branch mess. However, the leaves just grow back again in the spring.


How tall will the lettuce tree be?

The Albizia julibrissin, also known as the Persian sleeping tree can grow 6-10 feet tall when not pruned. You can keep this tree in nice shape and height by pruning it regularly.

Does the Persian sleeping tree get flowers? When?

In addition to its unusual leaves that close at night, the Albizia gets beautiful dainty panicle flowers from June through fall.

How old can an Albizia julibrissin grow?

These trees can get very old, which cannot be determined as a number of years. But they get older than you and I.

When should I prune my dormant tree?

The albizia doesn't mind being pruned. It is not like a palm tree where the lower leaves become dry and need to be pruned off, but in winter when the tree is outside it does lose its leaves. So if you want to prune the branches you can just do that.

When should I water the Albizia julibrissin?


The Albizia actually needs good water every day in the heat of summer. The root ball should not dry out. But during less hot days, it is best to wait a while. If the root ball is still slightly moist to the touch it's fine.

What kind of soil does the Albizia want?

A dormant tree likes good nutrient soil. For example, you can pamper the root ball with a bag of Florentus Mediterranean Nutrient Soil, specially developed for Mediterranean plants such as the Persian dormitory tree.

Why does an Albizia julibrissin get yellow leaves?

It may be that the dormant tree is not getting enough water during the growing season, or too much water e.g. in autumn, but it is also a natural thing that leaves become dry. Some leaves have simply reached their age and then die off. The leaves can be removed with scissors, or by hand.
