Appendix F – Label Source Guide and Standards<br />

As a general rule, plants in the collection are labeled with two brown anodized aluminum<br />

records labels. Gold records labels replace brown labels on specimens highlighted in selfguided<br />

tours.<br />

Trunk labels are mounted on trees with DBH greater than 15 cm using 3‛ stainless steel screws.<br />

Taxa with ornamental bark are typically not labeled in this manner to avoid scarring. Grove<br />

plantings and accessions with multiple qualifiers are labeled at the discretion of the Curation<br />

department.<br />

Trees<br />

Records labels are placed opposite one another on<br />

trees with low hanging branches. Accessibility is<br />

critical and every effort is made to hang the labels in<br />

conspicuous locations on stems that bear secondary<br />

branching.<br />

Trees without low-hanging branches are labeled by<br />

inserting a 3‛ stainless steel screw (square head) at<br />

an appropriate height (approximately 12‛) above<br />

soil line. Generally, screws are mounted on stems<br />

greater than 15 cm DBH; parallel to roads, paths,<br />

and trails; hidden from sight lines.<br />

In rare cases, records labels may hang from trunk<br />

label mounts (screws [preferred] or nails), however every precaution should be taken to avoid<br />

owl-eyeing (discoloration of bark due to label spinning due to loosely wrapped wire). Stakes<br />

can also be used to present records labels on young trees that do not have secondary branches.<br />

Shrubs<br />

Two records labels are hung on each shrub accession. One records label is affixed to a stake and<br />

placed at the base while an additional label is hung in a conspicuous location, roughly at waist<br />

height.<br />

Deep (> 10‛) stake insertion ensures relative permanency.<br />
