Showing the triple-compound-ness of the compound flowers.

The white petals are actually bracts, and have green tips. The triple-fractal nature of the flower heads can be seen more clearly here by observing the placement of the several sets of bracts. This belies the true nature of Pink Masterwort: it is an (albeit un-typical) umbellifer.

A single compound flower head. The florets are sometimes tinged pink, hence the name.

Some floret stalks (seemingly not all) are surrounded by a frilly green-striped barrel-shaped sheath.

The leaves are palmate, five-fingered and toothed, reminiscent of Cinquefoils.

The stems are ridged like many other Umbellifers.



Astrantia is not native to Britain, and any occurrences are probably garden escapees. The example shown here was a lone patch in the heavily grassed verges alongside the Worcester and Birmingham Canal on Midsummers day, 2006, an exceptionally warm year; indeed, the warmest for 350 years! There are two species, Astrantia minor, largely un-branched up to 70cm tall, and the largely similar but sturdier and branched Astrantia Major, which is up to 1m tall with an umbellifer-type canopy of flowers. The specimen shown is branched therefore Astrantia Major. The conspicuous white 'petals' are bracts, the real flowers are within and much smaller, but still white.
