About this plant
These are plants with charm and beauty, looking like lupins but far more delicate and with a very soft appearance. Some forms, Thermopsis montana in particular, have a tendency to run so need placing with care. These stand around a metre in height and may need staking when in flower. They are spring or summer flowering and the pea blooms are generally yellow.

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.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
