Introduced by Delbard in 1997 and sharing the name of Prince Rainier of Monaco, Grimaldi leaves a lasting impression of the exceptionally elegant beauty of Princess Grace of Monaco – delicate but strong. This robust and highly disease-resistant shrub rose which flowers from season start to season end and all the way in between, is a magnificent sight when planted in groups so that the flowering bracts can be supported and pushed upwards by each other.
Not caring about what the weather is, this magnificent shrub rose grows easily to 1.5mts and 1.2mts wide and just continues to produce branching canes of deep green foliage loaded with single, open and lightly fragrant blooms which, when cut, are very long-lasting in the vase.
Grimaldi is ideal for planting as a rose hedge-row, certainly en masse and should be pruned accordingly – with a mechanical hedger or shears.
- Highly disease resistant and easy-care rose
- Ideal for group and rose hedge-row planting
- Unusual salmon-pink-cream combination of colour
- Very low maintenance rose
The generally sunny, dry and hot conditions of the Australian garden are particularly well suited to planting roses and roses flourish in our gardens when you take measures to provide the following:
WATER – Roses are very deep rooted plants and require one good, deep soaking at least every 10 days in hot and dry conditions.
FEED – Because roses flower throughout all but the Winter season, they should be regularly fertilized with quality (preferably organic) fertilizer which contains a balance of major nutrients (NPK) and trace elements. The fertilizer should be applied at least once a month – small amount often – with fortnightly applications of liquid seaweed over the foliage.
PRUNE – During Winter, 70% of the rose plant should be pruned and all old wood removed back to the crown and the bush pruned to shape.
During the flowering seasons, 25% of all flowering stems should be cut back after flowering to encourage strong re-growth.
MULCH – Particular attention to application of lucerne or pea straw directly around the root-zone of each rose will enhance the overall health of the rose and then the whole bed should be mulched to 75mm with any other mulch medium available.
