Limonium from Tissue Culture- Perennial types

New for Fall 2026 from HilverdaFlorist! Limonium x altaica is a hybrid with a similar texture to L. sinensis. It is very delicate looking but is very cold and heat tolerant. HilverdaFlorist does not expressly state that these are L. x altaica types, but they look like it to me and the boast the hardiness and productivity associated with these sorts of hybrids. They are probably hardy down to zone 5, and maybe colder with good drainage and a bit of protection. We simply don't have hardiness data on this series yet. They are drought tolerant after establishment and are unbothered by heat in the summer. They may slow down a bit in the height of summer in very hot areas but should perk back up when cooler weather returns. They are similar to their L. sinensis cousins but the stems are a bit taller and wider and have an airier habit. Culture- Space 12 to 18" apart. When the first stems are emerging from the crown, pinch them out to encourage the production of even more stems. They should bloom well until frost. Grow in well drained to sandy soils. All Limonium need a couple of weeks of cold weather (35-45F) to initiate flower buds. This should happen naturally when planting in the fall. The goal is to establish a large crown of foliage over winter to support flower growth in the spring. Remove the first few stems as they appear to encourage strong vegetative growth.
