If you want a long-season burst of warm color without fuss, Geum 'Totally Tangerine' (Avens 'Totally Tangerine™') is an easy pick. You get bright apricot-to-tangerine, single blooms carried high above a tidy mound of fuzzy green foliage, so the flowers seem to float over the border. It is a strong bloomer and a great way to add lively orange tones from late spring into summer.
Plant it where it will receive full sun to part shade. In hotter climates, a bit of afternoon shade helps the foliage stay fresh, while morning sun keeps flowering strong. Give it average to consistently moist, well-drained soil; it tolerates a range of soil types but performs best when the crown is not sitting in soggy ground for long periods.
For the best display, deadhead spent flowers to keep new buds coming and maintain a neat look. Once established, keep an eye on watering during extended dry spells, especially in peak heat. Expect a mature height around 24-30 inches with a compact spread, making it easy to tuck into mixed borders and cottage-style plantings.
Geum 'Totally Tangerine' is also useful in containers and as a cut flower, and it is known for drawing in pollinators such as butterflies. Deer typically pass it by, which helps it hold up in many landscapes. Divide clumps every few years in spring or early fall to refresh growth and keep your planting vigorous.
