Lateral buds are small, tan, triangular, and appressed, pith is often chambered at the nodes.
Maintenance Little
Propagation Seed - best sown as soon as it is ripe in a cold frame. Stored seed is best given 2 - 3 months cold stratification and then sown February/March in a greenhouse. Germination rates are usually good, though the stored seed might take 12 months or more to germinate. The seed can be stored for up to 5 years. As soon as they are large enough to handle, prick the seedlings out into individual pots. The leaves of seedlings often have a lot of white patches without chlorophyll, this is normal and older plants produce normal green leaves. Grow the seedlings on in a cold frame for their first winter, and plant them out in the following late spring or early summer. Give them some protection from the cold for their first winter outdoors.
