A mature clump of globeflower will grow anywhere from 45 to 60 centimetres tall and wide.
In late May, and throughout most of the month of June, one of my favourite perennial plants puts on its spectacular show. The common globeflower (trollius europaeus) is a hardy, easy-to-care-for perennial that never fails to perform, year after year. The flowers of trollius can be yellow, orange or white and I much prefer the yellow variety which produces large blooms that are a pure lemon yellow.
Globeflowers like moist, rich soil, although once established, they are remarkably adaptable and thrive even when conditions are less favourable. If the late summer and fall are unusually dry, the foliage may dry off early if the plant is not watered. Generally, I find that the foliage remains attractive throughout the summer as I deadhead the spent blooms and shape the plant into an attractive clump.
My trollius is the older, common globeflower, but there are hybrids available, usually with tags that will say trollius cultorum. The blooms of the common globeflower are rounded and full and the hybrids have blooms that are more open with a single or semi-double appearance.
Globeflowers can be propagated by division which can be performed in the early spring and the plants should be divided every six years or so to keep them vigorous. A mature clump of globeflower will grow anywhere from 45 to 60 centimetres tall and wide. They are often recommended for use in a shade garden, but I have mine in a perennial bed that is fully exposed to afternoon sun and it performs well. I think in full shade the growth might be somewhat elongated and leggy.
My yellow trollius combines well with the mid-blue iris and a blue columbine in my garden that bloom about the same time as the globeflower. Globeflowers make wonderful cut flowers and are superb for flower arrangements. Individual blooms will last for a week as cut flowers – another way to enjoy this beautiful perennial. – Albert Parsons writes from
