It's the season for Chinese lanterns (Physalis peruviana). These are a popular ornamental plant that are very hardy, even below -20C. The ones used in this week's posy are garden escapees and with a wide-spreading root system this species can be quite invasive. Despite being part of the nightshade family (Solanaceae), when ripe, they have an edible berry - even M&S sell them!
What's in the posy?
Chinese lantern, chrysanthemum, pittosporum, brassica, bush lily, alstromeria, anemone.
Not much this week, sorry about that!
All of it! As every week, 100% British flowers and foliage throughout the year!
