Characteristics of Trillium Grandiflorum
Trillium Grandiflorums have short, thick rhizomes that produce a stem that grows between 15 and 45 cm tall. The leaves, called bracts, are usually round-ovate to sub-rhombic and grow between 8 and 15 cm wide and 10 to 30 cm long.
The stem has an erect pedicel between two and ten cm long where the flowers grow. The plant flowers between late April and early June, depending on the elevation and latitude you grow it in. The flowers usually have three white petals, measuring four to seven cm long, depending on the age and vigor of the plant.
They have a shape similar to the leaves but curve outwards, recurve in the middle to create a funnel-shaped corolla with a yellow center, and sometimes change to pink as they grow. They also have venation. But not as apparent as that on the leaves.
There are three flat, acuminate, green sepals below the flowers, with maroon or dark maroon streaks. Their color is usually paler than the leaves, spreading around 2.5-5 cm.
The flowers have a slender and straight stigma narrowing at the end, six stamens in two verticils of three, and white, short styles with yellow tips because of pollen. After flowering, the plant produces a pale green, six-angled, and ovoid berry with brown seeds.
