Leaf rust prevalent on purple big bluestem

Purple or dark red selections of big bluestem seem to be more susceptible to leaf rust, which shows up as orange or rust colored blotches on the leaf blade and sheath, and turns brown with age. Red October, shown below has quite a lot of rust. This is not fatal and is somewhat hidden in the darker foliage of these cultivars. Leaf moisture contributes to rust, so keeping the foliage dry does help.

Apache Rose and Blue Fountain Panicum

Apache Rose is a new mid-height switchgrass with soft rose flowers and green foliage, below right. On the left is Blue Fountain switchgrass which is a taller form, with showy white flowers amid the very blue, fairly wide foliage. Both of these look good as 1 year old plants (planted in fall 2015). One of the Blue Fountain has been slow to grow (front plant). There are 4 of each of these plants in the Grass Collection at the Minnesota Landscape Arboretum.

Cape Breeze Panicum

‘Cape Breeze’ switchgrass is much shorter than most cultivars, full of flowers here at the Minnesota Landscape Arboretum on July 26, 2016. It is about 30 inches in height, note the ‘Ruby Ribbons’ label to the left, and the ‘Cape Breeze’ label hidden in the foliage. There is a market and need for mid sized grasses that have good plant form. ‘Cape Breeze’ was discovered on Martha’s Vineyard, MA and is known for being a shorter plant.

Flowers in a ‘Bee Lawn’

Thyme and self-heal (Prunella) are starting to show up now amid a lot of white clover in the flowering or ‘bee lawn’ plots that were planted at the Minnesota Landscape Arboretum in 2015. Mowed at 4 inches, with not much of the fine fescue showing, these 5 treatments all have some clover. The scalped (mowed to almost nothing, 1″) prior to seeding plots show the most thyme and self-heal. For more information see Planting a Bee Friendly Lawn and Flowering Bee LawnsIMG_4359 - Version 2
