THALICTRUM FLAVUM 'ILLUMINATOR'
The variety ‘Illuminator’ is a robust plant, best noted for its attractive and showy young leaves which emerge bright golden-yellow in spring, changing to powdery blue-grey for the summer. Growing slightly taller than the species, it bears cloud-like sprays of fragrant lemon-yellow flowers, the perfume rather resembling that of elder, with yellow sepals and stamens, which appear in late spring to early summer. Plants are usually tall and narrow in habit, so staking is sometimes required. Clumps may be divided in early spring, but take a year or two to settle back in and reach a mature size.
Sow seeds IMMEDIATELY you receive them, at any time of the year, they depend on having several months, sometimes up to a year in cold, damp compost, (NOT DRY IN A FRIDGE) before they will germinate. Keep the seed tray moist in a cold greenhouse or shady corner and do not discard. These fresh seeds can be very slow to germinate but do not use any artificial heat in an attempt to germinate them as it may simply disrupt their germination mechanism causing them to enter even deeper dormancy.
