Safety
Not on ASPCA's toxic list, but NC State flags it for cats, dogs and horses and its former genus is toxic; keep pets from chewing it. per ASPCA and NC State
Worth knowing
A cool-weather plant: it flowers best when it is cool, stalls in high summer heat, then rebounds in fall. A mid-summer shear pushes it back into bloom. per Missouri Botanical Garden
Wet soil is the killer
Root, stem and crown rots are the main disease risk and come from wet, poorly drained soil, so sharp drainage is the best preventive. per NC State
Draws bees and butterflies
The open daisy flowers draw bees, birds and butterflies, and the long bloom season extends the forage window for them. per NC State
Bred into 200+ cultivars
Native to the Canary Islands and Madeira, it has been bred hard as a bedding plant: more than 200 cultivars registered in Japan alone. per PubMed Central
Grown as an annual
Frost-tender: in most of the US it is grown as a cool-season annual that will not survive freezing winters, so overwinter it frost-free or take cuttings. per Missouri Botanical Garden
What pairs well with Marguerite Daisy
Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
Perennial Sunflower
Shares full sun and moderate water; overlaps, then carries the display into mid fall; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Aster
Shares full sun and moderate water; overlaps, then carries the display into mid fall; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Goldenrod
Shares full sun and low to moderate water; overlaps, then carries the display into mid fall; its seed heads stand through winter, for structure and the birds; both offer pollinator forage.
Eastern Redbud
Takes full sun to part sun and moderate water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; a soft color beside the white.
Rosemary
Shares full sun and low to moderate water; opens in early spring and overlaps into this one's season; evergreen, so the bed keeps its shape through winter; both offer pollinator forage.
Hyacinth
Shares full sun and moderate water; blooms in early spring, before this one opens; lower at 10 in, for the front of the border; both offer pollinator forage, in different months.
Serviceberry
Takes full sun to part sun and moderate water; blooms in mid spring, before this one opens; both offer pollinator forage, in different months; its white flowers settle the white.
Flowering Crabapple
