Seed ripenslate September

Tall annual, with very upright form. The whole plant, leaves and flowers, is softly fuzzy. Lavender flowers with prominently veined lips start up just as the garden is entering its summer slump. In any year, this is a large plant - but they outdid themselves last season, when they grew taller and bushier than ever. They just kept on blooming till frost!
Their sheer size can be an asset, but be careful where you place it. Ours have taken to self-seeding in the cracks between the flagstone path around our pond, and charming as they are, they get mightily in the way. They have a slightly sticky feel to them, and the whole plant has a cloying scent - it's not exactly a bad smell, and not very noticeable until you get up close, but as garden fragrances go, I wouldn't rate it highly.

In our garden, this plant grows in the following area: waterfall pondside
