Description

Green lavender cotton is a small mounding shrub to 2 ft. high, spreading 3 ft. wide. Deep emerald-green scale-like leaves contrast boldly against bright yellow flowers during spring. It produces a very fresh and lush foliage character in dry garden settings.

Native to the Mediterranean region, this species provides deep green foliage character in addition to soft texture and bright flower color. The best growth occurs in full sun, on well-drained soils and with low amounts of supplemental water. It can be trimmed to function as a neat border plant, planted in rock gardens, on banks and in Mediterranean style plantings.

Water Needs

The green lavender cotton grows well in sunny locations on well drained soils and with low amounts of supplemental water during summer. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months marked by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water.

Maintenance

Prune annually in late winter or very early spring before flower buds develop (D). Pruning of multiple plants is easiest done with a manual hedge shear, while just a plant or two can be done with pruners. Prune to remove 1/3 to 1/2 of the average stem length of the leafy part of the stems, forming a compact mound shape. New invigorated growth will rapidly emerge. This annual hard cut back will keep the plant looking good and living longer. Santolinas that do not get this annual maintenance often get woody and decline in a few years after planting (S). Leggy mature plants can be cut back to a few inches tall just before spring growth begins to try to reset the form (5). They will usually grow back, but may not, so it is best to stay on top of more frequent annual pruning (S).
