  • Photo of Ranunculus sardous (Ranunculus sardouss)

Phonetic Spelling:ra-NUN-ku-lus sar-DOH-us

Genus:Ranunculus

Species:sardous

Family:Ranunculaceae

The petioles typically exceed an inch in length, connecting the hairy stem to the similarly hairy leaves, which are generally divided into three distinct leaflets.

The flower features five yellow petals and five reflexed sepals, with each petal measuring less than a third of an inch.

The achene fruits develop in clusters, sometimes numbering up to 35.

This plant is indigenous to the Canary Islands, North Africa, and Europe, flourishing particularly in disturbed and moist environments.

Often regarded as a weed, this broadleaf winter annual germinates in the fall or winter, remaining dormant until spring. However, unseasonably warm winter weather can prompt early growth. It reaches maturity and produces seeds in the spring, ultimately dying off in late spring or early summer. It has a tendency to outcompete weaker turf, especially in moist or shaded areas.

To effectively prevent winter annual weeds, maintaining healthy turf is essential. Choose a grass variety suited to your region and adhere to recommended practices for fertilization, mowing, and watering. The plant's low, broad growth habit is not significantly affected by mowing. Additionally, consider implementing various weed management strategies.

You might also explore alternatives to traditional lawns.
