How to Grow
Planting Dianthus plumarius ‘Itsaul White’ should occur in spring after the danger of hard frost has passed. The primary requirement for success with this Pink is excellent drainage; it thrives in average, medium-moisture, well-drained soils. Incorporating leaf mold or other organic material helps gritty loams retain slight moisture, which is beneficial during hot summers.
Ongoing care centers around moisture management and appearance. Water consistently, maintaining medium soil moisture, but avoid wet, poorly drained conditions, which can quickly lead to crown rot. While prompt deadheading prolongs the bloom period for Dianthus plumarius ‘Itsaul White’, busy gardeners might find it more practical to shear the entire plant back lightly after the main bloom flush to encourage the foliage cushion effect.
Division is a straightforward propagation method, best performed in the spring when new growth begins. Be mindful that Dianthus plumarius, in general, does not perform well where summer heat is intense and prolonged, so planting in an area that receives afternoon relief, if necessary, can improve longevity.
Landscape Uses
Dianthus plumarius ‘Itsaul White’ excels near the front of a border where its low height and fine foliage can be fully appreciated. Its use as edging along pathways or sidewalks highlights the neat, mounding habit of this Pink selection. It is equally at home providing seasonal color in cottage gardens or nestled among the foliage mounds of peony or rose beds.
For rock gardens, the need for sharp drainage makes this a perfect fit, particularly when paired with other sun-loving, gritty-soil companions such as Sedum or creeping Thyme. Because Dianthus plumarius ‘Itsaul White’ is so adaptable to containers, it can bring its signature fragrance and white blooms right up to seating areas or patios.
