Ginny's Plant of the Week comes to us from across the pond.
Phlomis tuberosa ‘Amazone’ is a member of the Lamiaceae with the common name of sage leaf mullein, and are native to Great Britain and Ireland. It is an herbaceous perennial that can grow 3-5 feet tall and 2-3 feet wide. They thrive in full sun but can tolerate light shade, and prefer to grow in organically rich, fertile moist but well drained soils. Plants have tuber like roots, and a long columnar 4 angled dark red to purple stems. They can bloom from May to July with tiny tubular lavender pink flowers that fit into a dense,
whorled clusters, blooming from the bottom up. Each stem can have up to 8 clusters. In late summer the flowers give way to ornamental seed heads which give texture through the autumn and the winter. When in bloom the flowers provide nectar and pollen to honeybees, native bees, butterflies and hummingbirds. The sage green leaves are deeply ridged and can appear quilted. The plants are cold tolerant in USDA zones 6-9 and when established
drought tolerant.
