Coreopsis

Meet coreopsis, the flower with the simplest good manners in the garden. A slim stem rises from a tuft of narrow leaves and carries a single golden daisy with notched petals, and a clump of them in a spring breeze looks like a flock of small yellow butterflies. It asks for sun, drainage and not much else.

Its native ground explains why. Wikipedia describes lanceleaf coreopsis as native to the eastern and central United States, preferring sandy, well-drained soil in full sun and adapted to extremes of wet and dry. NC State says it tolerates sandy and rocky soils and is resistant to deer, drought, heat and humidity. That list reads like a brief for a Dubai bed, though none of the sources tested it in the UAE.

The mood is meadow rather than formal: a loose drift along a gravel path, a patch at the edge of a lawn, a row of pots by the gate. The common name, tickseed, comes from the small seeds, which resemble ticks.

Coreopsis lanceolata, the lanceleaf coreopsis or lanceleaf tickseed, is a herbaceous perennial in the daisy family, Asteraceae. NC State gives a height of 30 to 90 cm and a spread of 30 to 60 cm, with yellow to orange flowers, and notes that it prefers full sun but tolerates partial shade of 2 to 6 hours, and that it sprawls if grown in soil that is too fertile. Wikipedia adds that it spreads to form colonies. The ASPCA lists the genus, Coreopsis spp., as non-toxic to dogs, cats and horses.

The sources agree on three things that matter in Dubai. NC State says it tolerates sandy and rocky soils and is resistant to drought, heat and humidity. Wikipedia says it prefers sandy, well-drained soil, copes with extremes of moisture and must not be overwatered, or it will flop; heavy clay that holds winter moisture can kill it. UF/IFAS says that once established it is drought-tolerant, and tells Florida gardeners to sow seed anytime from October through January, in a sunny spot, no more than an eighth of an inch deep. That is close to Dubai's cool season.

We found no Dubai Municipality or UAE source on planting dates or on how it performs through a Dubai summer, and no UAE nursery listing for the plant; the only UAE listing we found is lanceleaf coreopsis seed on Noon. The windows below are therefore our reading of the cool season, from the UF/IFAS advice and Dubai's climate. NC State also warns that it can become weedy and self-seed aggressively, so in a small bed deadhead before it sets seed.
