Hi Jim, thank you for your kind words! I’ll try my best to answer your question since both appear to look alike. Some of the diagnostic keys are: – Penny wort flowers are yellowish and a hint of purple. – Pennywort leaves , according to sources often have five to seven shallow lobes around the edge. – Ground ivy leaves are opposite and has hairy upper surface. – Ground ivy flowers are funnel shaped with blue to lavender. Best wishes to you Jim! Laura

Hi Laura, I very much appreciate your identification skills. How does one differentiate between the ground ivy and pennywort? The leaves seem very similar.

Sorry, I didn’t see all your posts when I logged on; it showed an unanswered post. Changing mine to: ‘Agreeing with Dichondra, possible D. carolinensis)

Bottom photo – Maybe a species in the pennywort (Hydrocotyle)? Possible lawn marshpennywort (H. sibthorpioides)? Control method for pennywort/dollarweed is in the above given link from Walter’s website. Link for lawn marshpennywort’s images. Check it out and see if you have a match. https://www.marylandbiodiversity.com/viewSpecies.php?species=2354

Top photo – Maybe a species in the Dichondra genus? Possible Carolina ponysfoot (D. carolinensis)? Check out Walter’s link for control method. Best wishes! https://www.walterreeves.com/landscaping/creeping-charlie-vs-pennywort-dollarweed-vs-dichondra-identification/

The first one looks like Kidneyweed (“Dichondra”). The second looks like Creeping Charlie (Glechoma hederacea). Here’s one possible source of advice for removing them: https://www.thespruce.com/how-to-kill-creeping-charlie-2131200
