That's not entirely true. I have grown Heuchera Firefly from seed in the past but it just did not excite anybody.
Heuchera villosa is commonly known as Allum root, hardly inspiring. They are from the Saxifragaceae famila and they are native to North Amercica. The Saxifraga family doesn't have many horticulturally common offspring but Astilbe is an excellent cut flower, Bergenia and Saxifraga are often used in rockeries and cottage gardens.
The old Heuchera Firefly has a marbled green foliage and small red flowers on spidery stems. Its great value is its toughness. Ideal for dry shady positions and perfectly capable of thriving in the sun... but boring.
Then we trialled some Hybrid Heucheras. We purchase tubes from Touch of Class Plants who in turn have sourced their plants from Terra Nova Nurseries in the US and they have a huge range of colours and leaf shapes.

Now don't get me wrong I still love the brightness and intensity of flowering plants but WOW. Mix and match the foliage shapes and colours of these beautiful, hardy plants and the results are stunning, particulary through winter and early spring and in positions where it is really tough to grow and flower many other plants.
We started selling plants this week as soon as they filled their pots and quickly ran out. So it will be a couple of weeks before we have more to pack and dispatch but they are definitely worth looking out for in your favourite Garden Centre
