Product description
Penstemon 'Windsor Red' is a bold and reliable garden perennial, celebrated for its elegant upright stems topped with deep crimson-red tubular flowers. These eye-catching blooms appear over many weeks, creating a vibrant display that brings a cottage-garden feel to any outdoor space. With its semi-evergreen foliage and upright form, this penstemon adds both colour and structure to borders and beds.
This hardy perennial performs best in moist but well-drained soil with good sun exposure, though it can tolerate partial shade. Flowering from June through to October, it offers a long season of interest and is especially loved by bees and butterflies. Regular deadheading will keep the flowers coming, and a layer of mulch in colder months helps protect the roots for winter resilience.
Ideal for adding height to perennial planting schemes, Penstemon 'Windsor Red' pairs beautifully with ornamental grasses and late-summer bloomers. It’s a great choice for pollinator-friendly gardens and thrives equally well in traditional borders or large containers. Its tall flowering spires also make excellent cut flowers, bringing a splash of colour indoors.
Please Note: Images are for illustrative purposes only and designed to be a representation of the item(s) being sold. Depending on seasonality, deciduous plants may be supplied in their dormant state and without leaves. Plants may also be pruned back, lower than stated heights, to encourage new growth. This plant will be supplied in a growers pot.

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 back penstemon plants after blooming to encourage new growth and prolong flowering.
How to Water
Water deeply but infrequently, allowing the soil to dry out between waterings. Avoid overhead watering to prevent mildew and root rot. Ensure good drainage, as penstemon dislikes sitting in wet soil.
How to Plant
Plant penstemon in well-drained, sandy or loamy soil in a sunny location. Dig a hole large enough to accommodate the root ball, and place the plant level with the surrounding soil. Space plants about 45cm apart to allow for growth.
