Description of Sarracenia purpurea subsp. venosa var. venosa f. pallidiflora
Sarracenia purpurea subsp. venosa var. venosa f. pallidiflora is a rare anthocyanin-free form of the southern purple pitcher plant. Stewart McPherson and Donald Schnell described it in 2011. Their published account records examples raised from seed in cultivation. Its main differences from typical venosa are the entirely green foliage and pale flowers.
The plant forms a low rosette of broad, swollen pitchers with open mouths. Each hood stands above the opening rather than covering it, and its sides curl slightly inwards. Fine, pale hairs line the inner hood, while short hairs cover the outer pitcher surface. The green colouring makes these details easy to see.
The foliage ranges from lime green to yellow-green, including the lip and throat. It lacks the red veins and purple colouring of normally pigmented venosa. This is a genetic absence of anthocyanins, not simply a greener appearance caused by shade. New growth and flower stalks also lack red pigmentation.
The name pallidiflora refers to its pale flowers. Instead of red petals, it produces pale yellow-green to cream petals beneath green sepals. The petals can lighten further as they age, sometimes approaching white. The flowers retain their familiar nodding shape, but their colouring matches the foliage rather than contrasting with it.
This form grows and divides slowly, so a small plant needs time to develop into a fuller clump. Allow it to establish before considering division, and judge progress over several growing seasons rather than expecting a rapid increase in growth points.
