The Palette Increases...

Today was another busy day around here with lots of staff and volunteers. We made two more plant runs and brought back another 12,000 annuals or so.. It was quite sunny, warm and windy so we're spending lots of time watering in the yard as we have lots of flats that will dry out very quickly in this type of weather. It looks like possible rain tomorrow but a hot and sunny weekend. Nice shot above of one of the irises (Iris germanica) in the collection that caught my eye recently. It doesn't have a variety name yet but is one of many that are currently blooming now. It looks like peak bloom for the majority of the irises will be in a week or so if the weather stays warm. Two Madison Area Iris Society representatives were here yesterday and thought things looked good and would still have some color for the early June tours by the conference attendees. Below is a shot of the seating area in the children's garden. We have lots of bright colors down there including the obelisks and the tree to the left is a golden Norway maple (Acer platanoides 'Princeton Gold') that is becoming one of my favorites for consistent golden color thru the summer.

Larry spent the day working on the koi pond and had some help from two RECAPPERS that Jumbo Jim brought down. Janice worked on some clean-up, watering and had her volunteer group here this afternoon for planting impatiens in the gazebo garden. Little Jerry worked on pruning in the Japanese garden while I did odds and ends between both plant runs. Being gone this morning, I'm not sure what the Grumpies did individually but we had a big crew (Ron W., Ron B., Gary, Ernie, Roger, Jim, Dick H., Big John, Bob C., Vern, Bob A., Jim D., Maury, Dr. Yahr, Dr. Gredler and Rollie). Projects included removing more plants from the formal perennial garden, mulching, composting, carpentry, etc. We also had Shirley, Glenna and Mary all working in the fern & moss garden clearing out old mulch and weeds. Big John (later joined by Ron W.) continued to compost this area. We also saw Dave, Bev, Mary W. and others over here today as well. The hosta to the left is called 'Designer Genes' and is known for its solid gold foliage and rich, red petioles. We have this in the woodland walk garden with another 50 or so interesting varieties. The small tree to the right is in the hosta hollow garden and catches my eye every year. This is the dwarf, golden vine maple (Acer circinatum 'Sunglow'). This tree, a native species to the West, has bright golden foliage in spring, chartreuse foliage in summer, then a nice plum color in fall. I love the leaves and this variety shouldn't get much over 8' tall and is very slow growing. Below is the native fringetree (Chionanthus virginicus) that is just starting to bloom at RBG. The sample below is from the Morton Arboretum (Lisle, IL) and check out that close-up. Both the males and females bloom but the females will get ornamental blue fruits in mid-summer. This tree is quite shade tolerant and really looks great this time of year. At the bottom is Golden Alexander (Zizia aurea) which is a neat, durable, native plant that is not commonly known.
