I have what is commonly called "Tulipa bakeri 'Lilac Wonder'". It's a pest, spreading overly freely and at this time of year shading out lesser plants in the same bed. Whether it's actually 'Lilac Wonder' I don't know, but the flower color is really a bright, strong pink with no hint of bluishness in it - hardly lilac. Plant it where it can spread to its heart's content without interfering with other plants. Tulipa sylvestris in a low, damp spot — standing water after heavy winter rains — where it multiplies like crazy but flowers very little. In another spot with better drainage, it flowers more freely, but I can't say if that patch has the same propensity to spread as does the water logged one. -- Rodger Whitlock Victoria, British Columbia, Canada Z. 7-8, cool Mediterranean climate
