Back when I was planning out a permaculture farm (a story for another time; I’m not a pro and I don’t have land yet), I was working out a companion planting scheme for my selection of crops, and decided to include flower strips (as well as herb strips) between crop rows in the plans. While plenty of useful companion flowers were standard inedible ornamentals, there were many in the list that had edible blossoms, bulbs or other parts. Some were added to the list merely for being edible ornamentals (the blooms would attract pollinators), while others had more complex companion plant value.
This is the list as it currently stands:
Chrysanthemum coronarium
Reichardia picroides
Tagetes spp.
Cosmos caudatus
Calendula officinalis
Taraxacum officinale
Chicorium intybus
Microseris lanceolata
Centaurea cyanus
Acmella oleracea
Carthamus tinctorius
Helianthus annuus
H. tuberosus
Dahlia spp.
Dianthus caryophyllus
Viola spp.
Pelargonium spp.
Papaver somniferum
Tropaeolum majus
Primula vulgaris
Campanula rapunculus
Polianthes tuberosa
Camassia quamash
Triteleia laxa
Tigridia pavonia
Lillium spp.
Hemerocallis fulva
Clitoria ternatea
Lupinus angustifolius
There were also a couple of minor roots that weren’t much for flowers, but seemed adequate for the list:
Conopodium majus
Bunium bulbocastanum
Perideridia gairdneri
Amphicarpaea bracteata
Lathyrus tuberosus
Right now I’m trying to collect some minor edible bulb flowers for my own garden. I’m currently looking for Triteleia laxa: three forms of it. The standard “Queen Fabiola”, and the much larger (and harder to find) “Sierra Giant” and “Humboldt Star”. Any leads for the latter two would be appreciated.
