We will keep you posted as later news becomes available.


The Covid-19 epidemic has caused serious disruptions to all the students and faculty at County College of Morris, so we have decided to postpone awarding a Blackburn Scholarship until next year. Best wishes to all of you and stay healthy.


Butterflies will soon be visiting our gardens and we'll want to make sure they are welcomed with the right kinds of host, food and nectar plants. Butterflies go through basically two kinds of eating stages: caterpillars consuming food plants and adult butterflies consuming flower nectar.

The host plants are the ones butterflies lay their eggs on so that when they hatch, the caterpillars will have a ready source of food, for example, Milkweed where the Monarch female lays her eggs and the hatching caterpillars eat the leaves.

Attracting butterflies to your garden is fairly simple as long as we keep their needs in mind. The best strategy is to plant a large area, with a variety of flowers that bloom over an extended period of time, Spring through Fall.

A combination of perennials and annuals works well because the perennials bloom for shorter periods of time and the annuals bloom for the whole season, filling in the gaps between perennial bloom times.

The following are good flower sources for Spring through Fall:

  • Spring: Rhododendron, Lilac, Allium, Lunaria, Chives, Cherry, Forget-me-Not, Honeysuckle
  • Summer: Ageratum, Heliotrope, Lantana, Scabiosa, Butterfly Bush, Coreopsis, Bee Balm, Phlox, Purple Coneflower, Zinnia
  • Fall: Verbena, Nicotiana, Cosmos, Zinnia, Sedum, Aster, Statice

Butterflies also like some wildflowers such as Dandelion, Clover, Queen Anne's Lace, Yarrow. Some folks think of these as weeds, but if you have an area in your garden that's a little out of the way, the butterflies will appreciate these flowers as well!

Another thing that will attract butterflies to your garden is an area where they can "puddle". Butterflies don't consume water like other creatures do, but a moist area in the soil where evaporating water has released minerals and sodium to the surface will attract certain species of butterfly such as admirals, skippers and swallowtails.

Studies have shown that most of the butterflies that engage in puddling are male, looking for the sodium important during the mating period.

Enjoy these delicate winged beauties as they flutter around your garden and feed on your flowers!
