Lupinus polyphyllus Russell Band of Nobles

The Russell Lupin, which can be found in all garden centers, is the ideal plant to test the pH of your garden at a low cost because it cannot tolerate any trace of active limestone. If the foliage of your lupin turns yellow, it means that your soil contains active limestone, if on the other hand it remains a beautiful dark green, it means that your soil is neutral or acidic. Simple, but effective! This series of hybrids, similar to the Russell hybrids, with beautiful palmate foliage in vibrant green, offers floral spikes in superb varied tones, such as violet and pale yellow, brick red and orange, or pale yellow and ochre. They are sold as a mix, so they will surprise you.
