Distinct showy flowers range in colour from white, pink and many shades of purple with a distinct orange eye. Blooms twice once in mid summer and again in early fall. Heavy flower spikes can reach 45cm in length bending the fine branching downward in graceful arches. The honey scent is sublime attracting many bees, butterflies and other nectar seekers. Semi evergreen in milder climates. Prefers coarse soil. Drought tolerant. Deer resistant. Blooms on new wood; can prune heavily to maintain tidy form. Seeds are dispersed by wind. Detests moist soils. Considered an invasive species in Washington & Oregon states. To prevent spread, trim off spent flowering spikes to thwart seed development.

How to germinate Buddleja davidii seeds:
Very fine seed. Surface sow. Barely cover with a layer of fine medium (silica sand) as seed needs light to germinate and needs to be anchored down. Mist well. Provide clear plastic cover and strong indirect light. Mist daily. Should germinate in 30 days. No pre-germination treatment needed such as cold stratification. Interesting note: in the Fraser Valley (Chilliwack has listed it as an invasive species) the coarse soils seem to be preferred as it self seeds readily even taking root along the road sides.
