About this plant
A handsome plant that makes a substantial mound of large oblong leaves that are covered in white tomentose (wool) over their green base. It sends up a long knobbly flowering spike that looks as though it is wearing a grey stocking mask. The flowers themselves are yellow, opening in June and July. This imposing plant is biennial in character and will cross-pollinate with other forms with gay abandon. The translation for the magnificent name 'bombyciferuml is "bumble bee bearing". This is found in parts of Asia Minor.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring, Summer, Autumn · Planting
Cut faded flower stems
Once all the blooms on the stem have opened and faded, cut the entire stem off.
Spring - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
Planting & general
