The Plants: Of the over 1500 perennials, a wide range is represented with bloom from late March to late October. Featured groups currently on trial include over 200 cultivars of Daffodils including several from the UK, over 100 perennial geraniums, over 60 astilbe, over 30 heuchera, over 30 pulmonaria, over 50 hosta, over 180 hemerocallis, over 40 siberian iris, about 30 monarda, over 40 garden phlox, over 45 asters, two dozen epimedium, about 4 dozen ornamental grasses, about 3 dozen fragrant shrub roses, and new introductions from the Blooms of Bressingham and Plant Haven programs. In addition, on trial are tropicals including plectranthus, phormiums and salvias; and new and unusual annuals including All American Selections and various sunflower varieties over the years. Various annual design combinations are changed yearly, both in beds and containers, to find combinations that work well together, and to photograph these for teaching and use in presentations. In addition to herbaceous trials, over 230 varieties of lilacs are on trial for hardiness, performance, disease resistance, bloom time and color, and photos (see separate lilac trial site).
Although in USDA zone 4A, microclimates on this property include zones 4B and 5A. Soil temperatures are monitored at various locations on the property, as well as soil moisture.

though each is a different cultivar, the spike form provides continuity),
yellows including several yellow-leaved annuals, among others.
These include Plectranthus and Salvia cultivars among others such as
Agapanthus and the non-tropical but tender Rosemary.

One of several typical beds having a succession of bloom: crocus, tulips
coming up through, Camassia behind the fence, to be screened later by zinnias
and sunflowers and amaranthus in front, with several perennials such as
delphiniums, and new varieties of New Guinea impatiens donated by Oglevee
interplanted with low sunflowers and forget-me-nots. Over 60 annuals, many
new or unusual, are being trialled. Sunflower
Trials were conducted in 3 years of over 60 cultivars.
