Noteworthy Characteristics

Lobulatia is a genus of 5 species of low-growing annuals and perennials from the Canary Islands and Mediterranean.

Genus name comes from the Latin word lobulus meaning small pod.

'Inlbusnopr', commonly sold in commerce under the trade name of SNOW PRINCESS, is an extremely vigorous hybrid form of sweet alyssum. It was discovered and selected in April of 2006 from a cross-pollination which occurred in a controlled greenhouse environment in La Palma, Canary Islands, Spain involving an unnamed selection of Lobularia canariensis (female parent) with an unnamed selection of Lobularia maritima (pollen parent). 'Inlbusnopr' is noted for its (1) outwardly spreading, mounding and cascading habit, (2) continuous flowering over a long period, (3) abundant fragrant single white flowers and (4) tolerance for hot summer temperatures. When planted in the ground, it will typically mound to 2-3' across. When grown in a hanging basket, it will typically droop to 3-4'. Dense clusters of sweetly fragrant, tiny, 4-petaled, white flowers cover the spreading foliage mounds from spring to frost. Flowering is often so profuse as to totally hide the linear, narrow-elliptic to lanceolate, gray-green leaves (to 1” long). U.S. Plant Patent PP21,594 was issued on December 28, 2010.


No serious insect or disease problems. Watch for slugs (particularly on young plants).


Mass in sunny areas of the landscape. Hanging baskets or large containers. Mixed containers as long as companion plants are also vigorous.
