Dianthus ‘Scarlet Fever’

Dianthus 'Scarlet Fever' perennial sweet william

Dianthus ‘Scarlet Fever’
(perennial sweet william)

Dianthus ‘Scarlet Fever’ forms large panicles of bright red flowers that appear on the ends of the sturdy stems that rise above the mound of green foliage. The pairing of Salvia ‘Maynight’ with Dianthus ‘Firewitch’ makes a perfect match. In our botanical gardens we have found the deer will eat Dianthus only in the winter. (This has been a problem) Dianthus has evergreen foliage that should not be trimmed. We recommend spraying Plantskydd late fall to prevent the deer from munching any of your plants, trees or shrubs. We sell Dianthus Dianthus ‘Firewitch’ and Plantskydd at the Plant Paradise Country Gardens organic perennial nursery and garden centre. Dianthus Dianthus ‘Firewitch’ was a Perennial of the Year award winner.

Perennial Catalog – 2019

All plant sales are in person at Plant Paradise Country Gardens in Caledon Ontario. As the 2017 Destination Garden Centre of the Year, we have been growing and selling hardy, unique and hard-to-find perennials organically for over 12 years. We are always trialing and testing them in the botanical gardens at Plant Paradise Country Gardens. Our growing practices benefit the whole environment, including the pollinators and beneficial insects.

At Plant Paradise Country Gardens we control every aspect of growing plants on-site. This begins with mixing soil in the potting shed and all the steps in between until the fully grown plants are ready for your garden. This gives us the opportunity to have control over the quality. Our responsibility is to grow healthy plants that are environmentally sustainable. We use only organic gardening methods to grow high quality plants without the use of pesticides, herbicides and synthetic fertilizers. Our plants are available in one, two or three gallon containers.

We DO NOT use NeoNicotinoids which is a pesticide used by many plant nurseries that sell to garden centres and big box stores. This pesticide is a known cause of the decline in the bee population. Everything a grower uses in plant production is systemically released into the molecular structure of the plant. This becomes a chain reaction in the long-term health and vibrancy of the plant and your growing environment.

By supporting our environmentally sustainable organic perennial nursery & garden centre you’ll be a part of the positive change that makes a difference in our environment. We believe you’ll see the difference.
