Nursery contributed plant descriptions

Allium flavum has open flower heads like exploding bright yellow fireworks. It is lightly scented and grows in the Mediterranean basin from France and Morocco east to the Black and Caspian Seas. Few plants can offer the unique flower forms of ornamental onions. Every garden should have Alliums. Plant in multiples of 3, 5, 7 or more. Don't fret when foliage starts to die back just before flowering. It's normal. Just trim the leaves.

Happy, bright yellow little explosions, otherwise known as loose umbels, nod in June and July. Should you suddenly find yourself in the alpine Austrian Tirol, look for these little lovelies on sunny, rocky knolls amongst Sempervivum, Saxifraga, Thymus, and Teucrium. 12" tall.
