Penstemon 'Wedding Bells' Mixed

Hardy Perennial

 Customer Rating

Penstemon cobaea 'Wedding Bells' (also known as Orchestra Mixed) combines some of the best penstemons from T&M's own breeding programme. Satin, bell-shaped flowers in a variety of bright colours and patterns are carried over a particularly long flowering period, above glossy, semi-evergreen foliage. A fantastic alternative to Antirrhinums (snapdragons) in annual bedding schemes, these compact penstemon plants boast large flowers and superb weather resistance. Easy to maintain, these hardy perennials are also attractive to bees. Height: 50cm (18"). Spread: 45cm (18").

Pot up penstemon plants and grow them on in frost free conditions until plants are well grown. Pinch out the growing tips while plants are still small to encourage bushier growth. When plants are well developed, acclimatise them to outdoor conditions over 7 to 10 days before planting them outdoors into borders and patio containers. Grow penstemon in a sunny or semi shaded position on fertile, well drained soil. Penstemons can tolerate dry soils once established but dislike heavy soils that are particularly cold and wet in winter. Improve heavy soils by adding plenty of coarse grit prior to planting.
Feed and water penstemons regularly until they are fully established. Once established they are reasonably tolerant of drought and will require little maintenance. Deadhead faded penstemon flowers to maintain the plant's vigour and encourage further blooms to be produced. In cold areas apply a dry mulch of bark chips of straw around the crown of each plant in autumn. Leave the old foliage intact until spring to protect plants during winter.

  1. Mixed?

    By Rosemary Gladstone 07-08-2015

    I received my order of these Penstemons in May and have been disappointed. I planted them in three different groups expecting to have a variety of colour in each. While the colour is nice every single plant has produced exactly the same reddish colour and far from being 18" tall they are barely a foot tall. I wonder what the description 'Mixed' refers to.

  2. Penstemon plugs

    By Paul Ormesher 22-10-2014

    I agree with Pauline, these do not travel well. I ordered 48 plugs on the 25th Sept and they arrived a week later. They did not look very healthy when they arrived but I potted them up anyway, a week later most of the plants have died.
