Pin Cushion Plants are only hardy in zones 9-11, however, they grow best in cooler conditions...
Pin Cushions require full sun or they will produce a lot of foliage and very few berries.
In hot summer regions, they maay need partial shade..
They should be planted in a sandy, well draining soil.
Give your Pin Cushion plant a half strength dose of a good all purpose fertilizer in early spring and mid summer.
Keep the soil evenly moist but not soggy.
