The Master Gardeners of Ulster County Cornell Cooperative Extension created this garden at Ulster Community College in Stone Ridge. Donations were provided by several local businesses.Distant view of Ulster Community College garden, showing lawn, trees and flower beds

The garden is near the main entrance to the campus. It is a demonstration xeriscape garden. A xeriscape garden requires little water and conserves water use. This is achieved by selecting plants that thrive in dry conditions, in particular native plants/trees/shrubs.  Mulch is used to conserve water in the soil and irrigation is kept to a minimum.

At the entrance to the garden there is a hand-built pergola covered in yellow trumpet vine campsis radicans

The garden consists of 11 island beds. Each bed has a theme such as Viburnum Bed, Nursery Bed, Herb Bed… Garden bench made from concrete uprights with a bluestone slab on top Pink evening primrose flowers and green foliage

The ‘Bench Bed’ includes a bluestone and concrete bench surrounded by sun-loving pink primroses Oenothera speciosa. Chokeberry tree, sedum, ornametnal grasses in a garden with ornamental 'river bed' made from pebbles

One of my favorites was the ‘River Bed’ which included a ‘river’ of pebbles. This dainty tree is a Chokeberry. It is native to NY, has white blossom in the spring and small fruit in the fall. The bright green sedum in front of the tree grows well on dry gravel.

The garden was teeming with pollinating insects, especially on this Globe Thistle Echinops

Prickly pear cactus with yellow flower

Many plants in the ‘River Bed’ were drought-tolerant species suitable for a xeriscape (minimal-water) garden, such as this Prickly Pear cactus Genus Opuntia in bloom. The fleshy pads are modified stems.

Grey Euphorbia Euphorbia myrsinites forms mats of slightly swirling stems, perfect for the ‘river’ themed bed.

Another of my favorites was the ‘Compost Bed’ I admired the way the compost bins were hidden – here’s the front, a planting of Spirea shrubs, silver-leaved Lambs Ears and beautiful grass Miscanthus Sinensis. spirea shrubs, lambs ears plants and ornamental grasses in a garden

And here’s the back of the bed. Plant pots, three compost bins and a tool box – all very neat and tidy unlike my garden. three garden compost bins, plant pots and tool box in a garden

The ‘Mouse Bed’ (I couldn’t figure out the reason for this name!) included a tall rudbeckia and purple coneflowers Echinacea species.

The ‘Milkweed Bed’ included Common or Swamp Milkweed which is food for the Monarch Butterfly caterpillar. The flowers smell like jasmine.

The ‘Butterfly Bed’ includes plants such as purple coneflowers that are attractive to skippers and other butterflies.

This garden is functional as well as beautiful, because it

  • Enables people to see hardy, drought-tolerant plants
  • Includes plants and trees that are native to NY or cultivars of native plants
  • Provides wildlife habitat, especially for insects and hummingbirds
  • Reduces the use of water and fossil fuels (lawn mowing)
  • Creates a space for people to unwind and enjoy nature

Relax and enjoy the moment in the shade of the pergola…and watch the hummingbirds visiting the trumpet vine.

Japanese Knotweed shoots in the spring

Japanese Knotweed Fallopia japonica is growing well in the Hudson Valley. Too well – it’s everywhere, including people’s gardens. It forms large stands, preventing all other plants from growing and eliminating habitat for wildlife.

Spring shoots

If it’s growing on your property, remove it as soon as possible before it becomes a  large clump which is much harder deal with.

Japanese knotweed stems. www.HudsonValleyGardens.us

The semi-woody stem is hollow

Identification

  • A herbaceous perennial that can grow over 5′ tall with stems 2″ wide.
  • Hollow stems look a little like bamboo.
  • In spring the shoots are a reddish color
  • The green stems have enlarged leaf nodes and may have red spots
  • The green leaves are alternate, 6″ long, 3-4″ wide and broadly ovate
  • In August, the flowers are greenish-white panicles in the axils of the leaves
  • In the fall the foliage dies back, leaving the dead woody stems standing

Removal

Barbara Bravo an experienced Hudson Valley gardener, Garden Coach and Master Gardener, recommends these steps for removing the plant.

  • Mowing or cutting to ground. To be effective, continue all season.
  • Use heavy black plastic sheets to smother plants
  • For large stands, the best method is to cut stems off at about 3′ high just below a stem node – use a squirt bottle and fill the hollow stem up ¼ of the way with 25 % Glyphosate (Use Rodeo if in a wetland or near water). Follow all instructions on the product label exactly to avoid contamination and over-use of chemicals.
  • In all cases, dispose of cut stems properly – the plant can resprout from stem or root pieces that are left on the ground.
  • Do not put the plant on a compost heap because it is possible to spread the plant when applying compost
  • Put the plant in a sealed bag in your trash can for garbage removal.
  • Complete removal may take several years, inspect the area often for regrowth and continue the removal process if needed.
  • Alternately, hire a professional Invasive Plant Removal company

How does this plant spread?

  • This plant has a horizontal, underground plant stem (rhizome) that produces a shoot and root system for a new plant. This rhizome can grow under surfaces such as concrete, bricks etc. until it finds a space to start a new plant.
  • It is also spread by seed

How did this plant arrive in the Hudson Valley?

Japanese Knotweed is native to Japan, China, Korea, and Taiwan and was brought to America in the late 1800s as a garden plant. It now grows wild because it can grow in a variety of soils, in sun or part shade and thrives in this climate.

Preventing the spread of Japanese Knotweed

In her excellent lecture about invasive plants in the Hudson Valley, Barbara Bravo explained “Gardeners are the first line of defense against invasive plants, if you see a plant that is thriving and you do not recognize it, do some research to identify the plant. If necessary, remove it”

I first met Barbara Bravo at a lecture she gave about the ‘Top Plants for the Hudson Valley Region’. During the lecture I learnt about plants that were the favorites of local expert gardeners – what a resource, I was busy taking notes for sure!

In November, Barbara is presenting another lecture on a very pertinent topic – Invasive Plants in the Hudson Valley. Unfortunately something that affects us all whether we realize it or not. I recommend this lecture because Barbara is an expert in gardening in the Hudson Valley Region. Here are the details:

When: Thursday, November 7 at 6:00 pm

Where: Cornell Cooperative Extension Ulster County Education Center. 232 Plaza Road in Kingston (Hannaford Plaza, the Cornell office is opposite Herzogs).

Each participant is asked to bring in one (1) weed to the lecture for identification.

Barbara will introduce participants to a few of the Hudson Valley’s most noxious weeds during her lecture. She says “Gardeners are in a good position to take action but need to be educated to recognize these plants. Be vigilant. If you notice some unusual and robust growth, especially if you didn’t plant it, identify the plant.”

As a resident of Ulster County, Barbara has more than 25 years experience gardening where the wildlife is plentiful and where she continues to learn peaceful co-existence. Her garden has been featured on the Saugerties Secret Gardens Tour and her articles have been published in Hudson Valley Life magazine. Barbara is a Master Gardener Volunteer with Cornell Cooperative Extension of Ulster County, a Garden Coach and Coordinator of Garden Day.
