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").

Flowering Months
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.
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.

Mixed? 2015-07-08

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.

T&M replied on 2015-08-07: Thank you for your review. I am sorry to learn of your disappointment with your Penstemons. If you would like to contact our Customer Care Department at, one of our agents will be more than happy to investigate this further.

Penstemon plugs 2014-10-22

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.

begonia plugs 2014-09-24

My begonias have been brilliant, a mass of yellow, apricot and orange blooms. I'm hoping to be able to keep some corms over winter. i would agree with the reviews about condition on arrival though. There were a few dead and damaged plugs on arrival which I was going to complain about but never got round to it. In my opinion T&M could put in a small percentage of extra plugs to cover the potential loss in transit. Cheaper than losing customers.

On the first batch 5 were dead the rest looked sorry I did let Thompson and Morgan know they were very good I received a new batch again, they did not travel good But the good news is I took great care in them and now My garden looks beautiful the plants are coming along nice and strong. Please don't give up on them

Condition of plants on arrival 2014-02-05

I ordered 12 plug plants for £9.99, and they arrived in an appalling state. The plants were not strong enough to cope with the rigors of the postal system. The packaging is inadequate; being shaken around in transit causes the plugs to be loosened from the holders. Most arrived loose in the packaging. Out of 12 plants I managed to get five to grow. I complained to T&M and they did send a replacement, but these arrived in a worse condition than the first lot. One plant was very clearly dead, and about four had the growing shoot broken off. I asked for my money back and it was duly refunded.
