The weather this spring in the UK (2021) has been quite extreme at times. April was a very dry month followed by a very wet and sometimes cold May. Now in June we are back to humid heat with little rain but there is still plenty of moisture in the ground. All this has resulted in a huge explosion of growth right across the garden.
We have grown Lupins for many years but I have been struck this year but the sheer size and exuberance of the plants we have around the garden. The top picture shows the brick red ‘My Castle’ in the foreground with the yellow ‘Chandelier’ and white ‘Noble Maiden’ behind. All of this is nicely framed by another member of the pea family, the Wisteria.
Many of the lupins we have around the garden are Russell Hybrids from the ‘Band of Nobles’ series. The species Lupinus polyphyllus is a native of western North America. It commonly grows wild along streams and creeks and prefers a moist habitat 1.
Lupinus polyphyllus was originally introduced into the United Kingdom by David Douglas in the 1820’s (2) . A century later George Russell started to develop the Russell hybrids with the aim of creating flower spikes that we denser, larger and more colourful than the original species. These were first displayed to the public at the RHS show in 1937 and have been a popular garden favourite ever since.
Over the last few years we have been developing our collection by growing from seed. It has proved to be a very successful way of growing a significant number of sturdy plants at little cost. In general we have sown the seeds in spring, potted up and grown on for about 12 months before planting out in the flower garden. The bigger the potted plant the quicker they seem to establish in the wilds of the flower garden where they have to compete with neighbouring plants and fend off the slugs. Most of the plants in these pictures are probably now three or four years old.
I particularly like lupins when they are planted in groups to make a strong vertical statement in a large bed. The range of colours is very wide and this allows you to mix and compliment these plants with a wide range of other border perennials.
