Plants that grow year after year.
Die back to the ground in the fall and grow back from the root in the spring.
Some perennials bloom from spring to fall, Coreopsis, Salvia, Geraniums, Gaura to a name a few.
Once planted they only need a small amount of work such as cutting back the old growth in spring & dividing every 3-4 years. Also in the spring it is good to work in some compost & or Bonemeal. I personally like to mulch the garden in the fall with well rotted real manure. Don’t forget spring weeding, unless they are planted real close together.
Many shapes, sizes, textures & colors. Something new or old for everyone.
From 2 to 6″ high, for sun, shade, part shade, wet, dry, containers, under trees almost everywhere you would like to make a garden.
Don’t forget, before you do any planting make sure you prepare the soil well in advance, one year if possible.
It is always a good practice to have the soil tested but if you don’t it is quite likely ,if you are in Nova Scotia, your soil is ‘sour’ and in need of limestone & the powdered or pelleted is the most fast acting. Also work as much compost into your soil as possible. Your perennials will hopefully be there a longtime and need feed to put on a great show.
