Veronica officinalis aka Speedwell

Veronica officinalis, also known as heath speedwell, common gypsyweed, common speedwell, or Paul's betony, is a perennial herb that is native to Europe and western Asia but has been introduced to North America and widely naturalised there. It belongs to the family Plantaginaceae (Scrophulariaceae) and is one of many Veronica species in the world. The plant grows 10-30 cm long and has a clambering, branched stem at the base that forms a timber. Leaves are narrow and inverse-ovate with serrated edges and slightly rough texture. Pale blue flowers with a purple tinge, or rarely white, grow in multifloral, flowering clusters from one bosom of two opposite leaves. The plant has astringent taste, and while fresh, it is without odor, but dried, it has a pleasant smell. It flowers from June to August. Common Speedwell is also a rare houseplant that prefers regular watering and well-draining soil. It thrives in long-lasting, direct light and should be less than 1 foot from a window. The plant does not need added fertilizers if repotted each time it doubles in size. However, if it grows as a weed, one can use Roundup Gel or ready-to-use spray, like Roundup Fast Action Ready-to-Use, SBM Job done General Purpose Weedkiller, or Doff Glyphosate Weedkiller Ready-to-Use, on patches of speedwell and leave the weed for three to four weeks for the weedkiller to take effect before removing dead foliage.
