More specifically, summer is weed flowering season.
Some of the weed flowers are uninspiring, and merely annoying—the dull greenish flowers of plantain, for example.
Others bring a splash of colour to what is normally a bleak time in the lawn.
Hawksbeard (Crepis capillaris) is one of the more prolific colourful weeds in the lawn in summer. An annual or biennial member of the dandelion family, this plant bears small, cheery yellow blooms on tall, branched stems.
The NZ Plant Conservation Network shows hawksbeard as being naturalised in 1867 from Europe. Like its cousin dandelion, it was most likely brought to New Zealand on purpose as a food plant—it’s young leaves are edible. Like the dandelion, it is no longer valued as a food, but is considered a weed.
I will admit, the tall flower heads of hawskbeard can be annoying in the lawn. They seem to spring up overnight between mowings, and they slap against your legs as you walk through the yard. But I do appreciate their yellow blooms at a time of year when most other plants give up from the heat and drought. I have been known to use hawksbeard in flower arrangements, and their green rosettes are sometimes the only green to be found around the yard.
