This is a scan from a medium-format transparency which I took at the Chelsea Physic Garden some time during the 1980s. It shows a tree of +<i>Laburnocytisus</i> 'Adamii', a so-called "graft hybrid" or "graft-chimaera". This tree was created by grafting a purple broom, <i>Cytisus purpureus</i>, onto a laburnum, and has flowers typical of both plants as well as some which are intermediate between the two. For more information, see <a href="https://en.wikipedia.org/wiki/en:%2BLaburnocytisus" class="extiw" title="w:en:+Laburnocytisus">'Adamii'</a>].
