Plant breeding at the nursery

Over the last 8 years we have selected and developed many new plat cultivars. This is the page about them. Propagating plant from seeds, from a wide collection of perennials and ornamental grasses, can result over the years in a very interesting combination of characters which can give rise to new cultivars. Occasionally spontaneous mutations or sports can arise from existing cultivars or species. Propagating them and testing their stability can result in new interesting and unique varieties of plants.

Lamium maculatum "Kalići's Select" (2012)

Lamium maculatum is a great perennial suitable for dry to moist shade having naturally variegated leaves. As the leaves matures they loose the central variegation and in the middle of the summer you can have a plain green plant. We wanted a plant with the same characteristics of the wild type but able to maintain the central variegation through the growing season. Lamium maculatum "Kalići's Select" is just like the wild type but "perennially variegated". The flowering is abundant and last for long. If you cut the plant to the ground after the first flowering you can have a new flush of flowers at the and of the summer. Height: 20 cm. Spread: to 40 - 50 cm.
