Can you take cuttings from Erysimum bowles mauve?
Take cuttings around 7. Heel cuttings (carefully pulling off the cutting with a piece of stem or ‘heel’ at the base) will often give better results. Prepare pots of suitable cuttings compost and water it well. Cut each stem into 6- to 8-inch lengths, so that each cutting has four nodes — that’s where leaves emerge on stems. Keep cuttings moist at all times. Remove all the leaves except one set at the top of each cutting. This helps cuttings root and helps you gauge their progress.
When to propagate bowles mauve?
You can raise new plants from cuttings in spring to early summer. Pull off side shoots with a small ‘heel’ and, ideally, choose non-flowering shoots, though this is rather difficult with Erysimum ‘Bowle’s Mauve’! Although western wallflower is technically a perennial plant, it’s often considered a biennial due to its short lifespan (rarely does it live past its second year).Though many people grow wallflowers as biennials – chucking them out after they have flowered – they are in fact short lived perennials and will live for 4 or 5 years in many gardens.Some are short-lived perennials and some hardy perennials. It’s a good idea to take cuttings of perennial wallflowers in case of losses.Wallflowers that become established in late summer bloom very heavily the following spring. Plants that persist as perennials, including the shrubby ‘Winter’ series, can be propagated by rooting stem cuttings taken in early spring.
