HTA Horticultural Consultant David Gilchrist said: "The Plant of the Month campaign highlights the plants that are widely available and looking especially good in garden centres each month." "British growers and retailers nominated and agreed upon Penstemon winning the title of ‘Plant of the Month' for June."
First popularised in the UK by Victorian plant-hunters such as David Douglas, Penstemons have since hybridised in nurseries providing the many cultivars now established as popular summer border varieties.
Easy to grow, these low maintenance plants require good drainage and a sunny garden position and can be used in borders or containers.
Most Penstemon plants are hardy, have a bushy habit and flower through summer to autumn.
The majority of cultivars can also survive a British winter if the crown is protected with dry mulch.
Some favourites this June:
Garnet: Popular floriferous Penstemon grows in a loose mound and has pink-red flowers
Firebird: Spectacular long lasting scarlet red flowers. Firebirds can grow up to a height of 1 metre
Port Wine: Vigorous cultivar with large deep purple flowers and foliage that flushes red in autumn.
