Verbascum 'Lavender Lass' should be watered moderately. Allow the top several inches of soil to dry out before watering. During the summer months, water approximately twice a week; however, during winter, once a week should suffice. It is important to check the moisture of the soil by using your finger before using a watering can to ensure they do not become waterlogged, as Verbascum plants are prone to fungal infections if given too much water.

Verbascum 'Lavender Lass' is a full-sun plant, meaning it requires 6 or more hours of direct sunlight each day to thrive. The ideal time of day for this plant to receive sunlight is morning and early afternoon, as this will give it a full 6 hours of sunlight without increasing the risk of sunburn or wilting. For best results, try to provide as much sunlight as possible by placing this plant in an area with ample direct sunlight for most of the day or by supplementing natural light with a fluorescent light bulb no more than 12" away from the plant. Avoid excessive clouds or shadows during midday, as these can block the sun’s rays. Too much shade also can cause the Verbascum 'Lavender Lass' to become spindly as the plants stretch for more light.

Verbascum 'Lavender Lass' should be pruned in late summer, after flowering has finished. Pruning should be done lightly to remove spent blooms and to help maintain the desired shape. It is best to use sharp pruning shears to avoid any rotting of the plant. When pruning, make sure not to remove more than 1-third of the plant’s foliage at a time as this can shock the plant. Pruning too harshly can also delay flowering, so it is important to only remove what is necessary. If verbascum become too tall, it is important to support it with stakes or canes to avoid it falling over.
