[Correct name is: Digitalis grandiflora] Yellow Foxglove (di-gi-TAH-lis: am-BIG-u-a) Scrophulariaceae:
Large bell shaped yellowish flowers. The flowers have some brown markings inside their throats. Plants grow 24 to 30 inches tall and flower in late spring and early summer, if cut back plants tend to flower again. Like most foxglove species, this plant is poisonous but I have never heard of any one eating enough of the plant to do real harm. Nice addition to an open shade garden, especially if you let it self seed around rocks and paths and it forms small clumps of naturally grouped plants. Grow in moist but well drained soil, wet soil will cause root rot and dry soil negatively impact flowering. Grows well in part shade, plants live and bloom well for about 5 years. Digitalis ambigua is easy to grow from seed, will bloom the second year.
Surface sow, light needed for best germination, Germination takes 10-21 days at F 70.
