Product description
Better known as the Obedient Plant, Physostegia ‘Crystal Peak White’ brings a fresh, luminous quality to the garden with its upright spires of pure white blooms. The tubular flowers sit neatly on strong stems, creating a clean vertical line that lifts borders and adds a sense of calm structure. Its compact form makes it easy to place among other perennials, where the bright blooms catch the light beautifully, enticing bees and butterflies throughout the summer months.
Thriving in full sun or partial shade, this variety prefers moist but well draining soil and settles quickly into beds, borders, or containers. Regular deadheading helps extend the display, while a light trim keeps the plant looking tidy as the season progresses. Supplied ready to plant out for instant impact, Crystal Peak White offers dependable growth, elegant colour, and a quietly striking presence that returns year after year.

Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
Cut Physostegia stems back after flowering to encourage a fresh flush of growth and keep the plant looking tidy.
How to Water
Keep the soil consistently moist while the Obedient Plant settles in, ensuring it never dries out completely during its early growth. Once established, it benefits from steady moisture through the warmer months to support strong stems and a reliable display of flowers.
How to Plant
Set the Obedient Plant into prepared soil at the same depth it was growing in its pot, choosing a spot with full sun or partial shade. Space plants 25-30cm apart so the upright stems have room to develop without crowding neighbouring plants.
